Description

Adjust interior lighting based on dynamic glass shading

Certain embodiments disclosed herein relate to controllers and methods for controlling one or more tintable windows and/or other building systems.

Electrochromism is the phenomenon in which materials exhibit reversible, electrochemically mediated changes in optical properties when placed in different electronic states, usually as a result of undergoing a voltage change. The optical property is typically one or more of color, transmittance, absorptivity, and reflectance. One well known electrochromic material is tungsten oxide (WO ₃ ). Tungsten oxide is a cathodic electrochromic material in which the color change (transparent to blue) occurs by electrochemical reduction. Electrochromic materials can be incorporated into, for example, windows for domestic, commercial, and other uses. The color, transmittance, absorptivity and/or reflectivity of such windows can be changed by inducing changes in the electrochromic material, ie, electrochromic windows are windows that can be dimmed or brightened electronically. Applying a small voltage to the electrochromic device of the window will darken it, and reversing the voltage will brighten it. This capability allows control of the amount of light passing through the window and opens up the opportunity for electrochromic windows to be used as energy saving devices. Although electrochromic was discovered in the 1960s, unfortunately, despite many recent advances in electrochromic technology, equipment, and related methods of manufacturing and/or using electrochromic devices, electrochromic devices and especially Series electrochromic windows still suffer from various problems and have not yet begun to realize their great commercial potential.

Certain aspects relate to methods and systems for adjusting building systems (eg, adjusting interior lighting based on dynamic glass tinting) to maintain environmental conditions. One aspect relates to control logic for adjusting interior lighting to enhance color appearance and/or offset contrast ratios through one or more tinted windows in a room. Described herein are thin film optical devices, such as electrochromic devices for windows, and methods and controllers for controlling transitions and other functions of tintable windows using such devices. Certain embodiments include an electrochromic window having two or more colored (or colored) regions formed as physically separate regions, for example, from a monolithic electrochromic device coating or Colored regions are established in the monolithic device coating. Colored regions may be defined by means of means for applying a potential to the electrochromic device and/or by resistive regions between adjacent colored regions and/or by physically bifurcating the device into colored regions. For example, a set of bus bars can be configured to apply a potential across each of the individual colored regions of the monolithic electrochromic device to selectively color the regions. The method can also be applied to groups of one or more tintable windows, where individual windows are tinted independently of other windows in order to maximize occupant experience, ie, glare control, thermal comfort, and the like. Certain aspects relate to an insulating glass unit (IGU) comprising a first window comprising a first electrochromic device disposed on a first transparent substrate and comprising a plurality of operable Independently controllable colored regions and resistive regions between adjacent independently controllable colored regions. The IGU further includes a second window and a spacer between the first window and the second window. In one instance, the second window includes a second electrochromic device disposed on a second transparent substrate. In one case, the IGU further includes a daylighting zone located, for example, in a top portion of the IGU, wherein the daylighting zone includes a daylighting zone maintained in a decolorized state to allow sunlight to pass through the first window and the second window. or multiple shaded areas. One aspect relates to a method of automatically controlling the color of light in a room having one or more tintable windows. The method includes determining adjustments to artificial interior lighting in the room to obtain a desired light color and sending control signals to adjust the artificial interior lighting over a communications network. The adjustments are determined based on the current tinting state of each of the one or more tintable windows. In one example, the desired light color in the room is associated with reducing the contrast ratio in the occupied area to within an acceptable range or below a maximum contrast ratio. One aspect relates to a controller for automatically controlling the color of light in a room having one or more tintable windows. The controller includes: a computer readable medium having control logic; and a processor in communication with the computer readable medium and with the one or more tintable windows via a communications network . The control logic is configured to: determine adjustments to artificial interior lighting in the room to obtain a desired color of light in the room, wherein the adjustments are determined based on a current tinting state of the one or more tintable windows ; and sending a control signal for adjusting the artificial interior lighting via the communication network. One aspect relates to a method of controlling environmental factors of a scene in a workplace having one or more tintable windows. The method includes: determining a type of workplace and a type of occupancy; defining a set of environmental factors based on the availability of controls for building systems; a target level for the environmental factor; determining adjustments to the building systems to achieve the target level for the environmental factor, wherein the adjustments are determined based on the current tinting level of the one or more tintable windows; and Control signals for adjusting the building systems are sent via a communication network. One aspect relates to a controller for automatically controlling environmental factors of a scene in a workplace having one or more tintable windows. The controller includes: a computer readable medium having control logic; and a processor in communication with the computer readable medium and with the one or more tintable windows via a communications network . The control logic is configured to: determine occupancy in the workplace; determine a type of workplace and a type of occupancy; define a set of environmental factors in the scenario based on the availability of controls for building systems; the type of site and the type of occupancy to calculate the target levels for the environmental factors of the scene; determine the adjustments to the building systems used to obtain the target levels for the environmental factors, where the one or determining the adjustments based on current tinting levels of a plurality of tintable windows; and sending control signals for adjusting the building systems via a communication network. These and other features and embodiments will be explained in more detail below with reference to the drawings.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the presented embodiments. The disclosed embodiments may be practiced without some or all of these specific details. In other instances, well known control operations have not been described in detail so as not to unnecessarily obscure the disclosed embodiments. While the disclosed embodiments will be described in conjunction with specific embodiments, it will be understood that no limitation of the disclosed embodiments is intended. Certain embodiments set forth herein, although not so limited, are particularly suitable for use in electrochromic devices. Certain embodiments are described with respect to techniques for controlling one or more tintable windows or controlling tinted regions in a multi-region window. It will be appreciated that these techniques may also be used to tint individual windows in groups (or zones) of tintable windows, in multi-zone windows, or combinations of such windows. Additionally or alternatively, these techniques can be used to control various building systems, including systems with one or more tintable windows. I. Introduction to tintable windows Certain implementations set forth herein relate to controlling tinting and other functions of tintable windows (eg, electrochromic windows). In some embodiments, the tintable window is in the form of an insulating glass unit comprising two or more panes and a spacer sealed between the panes. Each tintable window has at least one tintable window/pane with an optically switchable device. Some examples are set forth herein with respect to a tintable window having an electrochromic window with an electrochromic device disposed on a transparent substrate such as glass. In one embodiment, an electrochromic window has a monolithic electrochromic device disposed on at least a portion of the substrate that is in the visible region of the tintable window. A detailed example of a method of making an electrochromic window with multiple tinting zones can be found in U.S. Patent Application Serial No. 14/137,644, entitled "Multi-Zone EC Windows," and filed March 13, 2013 (issued as No. 9,341,912), which application is hereby incorporated by reference in its entirety. As mentioned above, some of the techniques discussed herein are related to controlling the functionality of tintables (eg, in one-zone and/or multi-zone windows) and/or controlling other systems in a building. - Resistive Zones in Multi-Zone Window Some of the techniques discussed herein relate to independently controlling each of the tinted (or tinted) zones in a multi-zone tintable window, such as a multi-zone electrochromic window. "Resistive region" (also sometimes referred to herein as "resistive region") generally refers to a region in an electrochromic device in which the function of one or more layers of the electrochromic device is impaired (partially or completely), but the device function is not cut off across the resistive zone. In one embodiment, the colored regions of an electrochromic window are defined by resistive regions between adjacent colored regions by the technique used to apply potentials to the electrochromic device to independently control the coloring in the colored regions. For example, a single set of bus bars or multiple sets of different bus bars can be configured to independently apply a potential to each colored region to thereby selectively color it. With respect to the resistive region mentioned above, this region allows independently controllable coloring of adjacent colored regions of a single monolithic electrochromic device without compromising the coloring functionality in the resistive region itself. That is, the resistive area can be colored. One advantage of these techniques is that scribe lines are not used to cut the electrochromic device between colored regions. These scribe lines may create non-functional areas of the electrochromic device that may produce visually perceivable bright lines in the visible area of the window when tinted. Instead, the resistive region can have a gentle gradient of coloring between adjacent colored regions that remain in different colored states. This color gradient blends the color transitions between adjacent colored regions to soften the appearance of the transition regions between the colored regions. In some examples, the multi-region window has resistive regions in the region between adjacent colored regions of the monolithic electrochromic device. These resistive areas allow for a more uniformly colored front surface, for example when used in conjunction with bus bar power delivery schemes. In some examples, the resistive regions are relatively narrow, having a width between about 1 mm and 1000 nm wide, or relatively wide, having a width between about 1 mm and about 10 mm wide. In most cases, the electrochromic material in the resistive area is colored such that it does not leave the bright line contrast effect that conventional laser isolated scribe lines typically leave. Thus, in other examples, the resistive region may be wider than 1 mm, wider than 10 mm, wider than 15 mm, etc., for example. The reason the resistive region can be colored is because instead of physically bifurcating the electrochromic device into two devices, it physically modifies a single electrochromic device and/or its associated transparent conductor within the resistive region. A resistive region is a region of an electrochromic device in which the activity of the device, specifically the resistivity and/or resistance to ion movement, is greater than the rest of the electrochromic device. Thus, one or both of the transparent conductors can be modified to have increased resistivity in the resistive region, and/or the electrochromic device stack can be modified such that ions move in the resistive region relative to the adjacent colored region The stacking of electrochromic devices is slower. In this resistive region, the electrochromic device still operates, coloring and decolorizing, but at a slower rate and/or with less tinting intensity relative to the rest of the electrochromic device. For example, a resistive region can be colored as fully as the rest of the electrochromic device in an adjacent colored region, but the resistive region is colored much slower than the adjacent colored region. In another example, a resistive region may not be as fully colored as an adjacent colored region, or colored in a gradient of coloring. U.S. Patent Application 15/039,370, filed May 25, 2016, entitled "MULTI-ZONE EC WINDOWS" and International PCT Application, filed December 18, 2014, entitled "MULTI-ZONE EC WINDOWS" Details of the resistive regions and other features of multi-zone electrochromic windows are set forth in PCT/US14/71314, both of which are hereby incorporated by reference in their entirety. II. Shading Considerations The motivation for controlling the tint state of one or more tintable windows and other building systems is for the good of occupants and/or solely for building considerations, such as energy savings, power requirements, and the like. Here, "occupant" generally refers to one or more individuals in a particular room or other space where one or more tintable windows are controlled, and "building" generally refers to the building management system (BMS) and lighting , HVAC and other building systems. Motivations related to occupancy include, for example, overall health as may be affected by the lighting in a room and the aesthetics of a tinted window or group of tinted windows. Motives include, for example, control of glare from direct sunlight hitting the occupant's workplace, visibility through the window to the exterior of the building (its "view"), tintable window colors, and associated The color of light, and the thermal comfort obtained by adjusting the coloring state to block direct sunlight from entering the room or to transmit direct sunlight into the room. While occupants may want to largely avoid glare reaching their workplace, they may also want to allow some sunlight to pass through the windows for natural lighting. This may be the case when occupants prefer sunlight to artificial lighting from, for example, incandescent, light emitting diode (LED) or fluorescent lighting. Additionally, it has been found that certain tintable windows may impart too much blue to a room in their darker tinted state. This blue color can be offset by allowing a portion of unfiltered daylight into the room and/or by artificial lighting. User motivations related to buildings include reducing energy use through reductions in heating, air conditioning, and lighting. For example, one may want to tint a window so that a certain amount of sunlight is transmitted through the window so that less energy is required for artificial lighting and/or heating. We may also want to harvest sunlight to harvest solar energy and compensate for heating needs. Another consideration, perhaps common to building managers and occupants, has to do with safety issues. In this regard, it may be desirable for the windows to be tinted darker so that occupants cannot be seen by those outside the room. Alternatively, it may be desirable for the window to be clear so that, for example, neighbors or the police outside the building can see inside the building to identify any malicious activity. For example, a user or building operator can put a window into an "emergency mode," which in one instance clears the window. a. glare control In many cases, glare avoidance can be the reason for as much as 95% of tinting decisions for tintable windows. The approach to making tinting decisions for tintable windows taking into account glare avoidance is described in detail in International PCT Application No. PCT/US15/29675, filed May 7, 2015 and entitled "CONTROL METHOD FOR TINTABLE WINDOWS" For example, this application is hereby incorporated by reference in its entirety. In these methods, glare is addressed in the operation of Logic Module A using proprietary control logic trademarked under the name Intelligence® (manufactured by View, Inc. of Milpitas, California). In module A, a decision is made whether to adjust the tint state of a tintable window based on the depth of penetration or area of glare caused by solar radiation entering the room through the window. If the penetration depth or glare area in which solar radiation hits the room overlaps with the occupant's position or likely position (occupancy area), the tintable windows in the façade remain in or transition to a darker tinting state in order to reduce this occupancy area of glare. Existing algorithms tint, for example, an entire set of windows associated with a building space based on glare at the expense of other user comfort considerations. The methods herein address glare by independently tinting individual tinting zones of one or more windows in a set of tintable windows and/or one or more multi-zone windows, for example, while also allowing natural daylight to enter the space And thus provides granularity and flexibility to tinting decisions by simultaneously addressing multiple occupant comfort issues and/or building system requirements. For example, reducing glare is a goal that is often at odds with reducing a building's heating load, increasing natural lighting, and the like. In winter, for example, the energy used by the heating system to heat a room can be reduced by clearing the tintable window, which may also create glare situation. In certain configurations described herein, a multi-zone tintable window (or individual windows in a group of windows) can be controlled to be tinted by dimming in that window (or a subset of windows in a group of windows) To solve this problem, limit the area of the occupant to those colored areas that reduce glare at the occupant's position or possible position in the room. While many examples are set forth herein with respect to controlling tinting zones in a multi-zone tintable window, it will be understood that similar techniques would apply to assemblies of multiple tintable windows, each tinting window having one or more tinting zones . For example, an assembly of tintable windows can be controlled to limit areas of the window assembly that are placed in darkened tints to within those tintable windows and/or tintable windows that reduce glare on occupied areas. Colored area. b. adjust color vision Other implementations for controlling the tintable window in a particular manner may reduce the color perception of the window in its tinted or decolored state and/or the color perception of the color of light passing through the window in its tinted or decolored state. Such implementations utilize optical properties that minimize the perception of undesired colors associated with particular tint states. As one example, the dimmed colored state of an optically switchable device (eg, an electrochromic device) can have an occupant-perceivable blue color. However, occupants may be less likely to notice the blue color of a tinted window if the tinted window in the room is juxtaposed with a more daylit clear zone window. For example, a particular window may be in a darker tint and may appear blue to occupants. In one embodiment of the glare-reducing tinting configuration, adjacent or adjacent windows can be left clear as long as they do not glare to occupants due to their relative position. Light passing through clear windows reduces the perception of blue that occupants might otherwise perceive. In another embodiment, a diffusing light source, such as a diffusing or scattering film adhered to a tintable window, can reduce the perception of blue in the tinted window. For example, a diffusing or scattering film may be disposed on the counterpart window of an electrochromic window of an IGU. In another example, a diffusing or scattering film may be disposed on the surface of a window without an optically switchable device, such as an electrochromic device. c. light collection Other tinting configurations may involve maximizing light collection. Light harvesting is the concept of converting solar radiation from the outside of a window into electrical energy for use by the window, building, or for other purposes. Light harvesting may be accomplished using photovoltaic films, other photovoltaic structures, or other light harvesting structures on appropriate portions of the window, such as on a mating window of an IGU. In one example, light harvesting is accomplished by photovoltaic cells disposed in or on the electrochromic window. One consideration is that photovoltaic cells or other light harvesting structures may be most effective when the incident light being collected enters in a normal or near normal direction. This can be facilitated by having a structure in the window that redirects light incident on the window so that it strikes the photovoltaic cell in a normal or near normal direction to maximize energy production. In some cases, a light diffuser or horizontal directing structure may be used on one portion of a tintable window to direct light onto a photovoltaic film, other photovoltaic structure, or other light harvesting structure on an appropriate portion of the window, such as on a mating window pane . Another consideration is that it may normally be desirable for the photovoltaic film on the counterpart window to be as transparent as possible. However, photovoltaic films made transparent are often relatively inefficient at converting sunlight to electrical energy compared to less transparent films, or films that are not only opaque but perhaps scatter light to a greater extent. Recognize that in one area of the window there may be certain tinted areas that are generally responsible for preventing glare situations in the room and therefore generally must be tinted, and/or outside this area there may be areas where the occupant would normally be able to view the outside environment certain areas. In one embodiment, the colored regions in this region have a photovoltaic film that is more efficient at light harvesting but more scattering or less transparent than regions outside of this region. In another embodiment, the colored areas in this region have a photovoltaic film, while the regions outside of this region do not have a photovoltaic film. Regarding the situation in which the incident light is directed, reflected, scattered or diffused horizontally in this zone because the upper area of the window produces most of the glare, similarly, according to another embodiment, the upper area of the tintable window may be equipped with more effective, But optically less pleasing type of photovoltaic film. -IGU Exemplary Locations of Photovoltaic Cells on Window Faces In certain embodiments, a tintable window includes photovoltaic (PV) cells/panels. The PV panel can be located anywhere on the window as long as it can absorb solar energy. For example, a PV panel may be located fully or partially in the visible area of the window, and/or fully or partially in/on the frame of the window. Details of examples of electrochromic windows with PV cells/panels can be found in U.S. Provisional Patent Application 62/247,719, entitled "PHOTOVOLTAIC-ELECTROCHROMIC WINDOWS," filed March 25, 2016, which is hereby incorporated by reference The method is integrated as a whole. The PV cell/panel may be implemented as a film covering one or more surfaces of the pane of a tintable window. In certain embodiments, the tintable window is in the form of an IGU having two individual windows (panes), each having two surfaces (not counting the edges). Counting inwards from the exterior of the building, the first surface (i.e. the outward-facing surface of the exterior window panel) may be referred to as Surface 1 (S1), the next surface (i.e. the inward-facing surface of the exterior window panel surface) may be referred to as surface 2 (S2), the next surface (i.e., the outwardly facing surface of the inner window panel) may be referred to as surface 3 (S3), and the remaining surface (i.e., the facing surface of the inner window panel The inner surface) may be referred to as surface 4 (S4). PV thin films may be implemented on any one or more of surfaces 1-4. In certain examples, a PV film is applied to at least one of the surfaces of the windows in an IGU or other multi-pane window assembly. Examples of suitable PV films are commercially available from Next Energy Technologies Inc. of Santa Barbara, CA. In some cases, the PV film can be an organic semiconductive ink and can be printed/coated onto the surface. Conventionally, where PV cells are intended to be used in conjunction with multi-zone electrochromic windows, the EC device is positioned towards the interior of the building relative to the PV cell/panel such that the EC device does not reduce the PV while the EC device is in the tinted state. Energy harvested by battery/panel. Thus, PV cells/panels can be implemented on the outwardly facing surface of the outer window panel (window), eg on the surface 1 of the IGU. However, certain sensitive PV cells cannot be exposed to external environmental conditions and thus cannot be reliably implemented on outward-facing surfaces. For example, PV cells may be sensitive to oxygen and humidity. To address the air and water sensitivity of such PV films, the film can be positioned on surface 2 or 3, thus helping to protect the film from exposure to oxygen and humidity. In some cases, a stack of electrochromic materials is on surface 3 and a PV film is on surface 2 . In another example, a stack of electrochromic materials is on surface 2 and a PV film is on surface 3 . In one aspect, the PV film is on S3 and the multi-zone window has an electrochromic device with multiple colored zones on S2. In such a case, one or more zones may remain in a decolorized state, such as in a daylight tinted zone that allows a high degree of natural light into the room (eg, in a transom window configuration). In this case, sunlight is fed to the PV film on S3, while other areas (eg, lower windows in transom window configurations) can remain tinted, eg, for glare control. In this case, the PV film receives sunlight and does not require light. 4. contrast ratio As used herein, "contrast ratio" refers to the contrast in intensity of light reflected from a surface illuminated by multiple light sources. In most instances the contrast ratio is stated with respect to two regions of the surface illuminated by multiple light sources, referred to as "first part" and "second part". The first portion refers to the area primarily illuminated by the first light source providing illumination with a first intensity. The second portion refers to the area near or around the first portion that is illuminated by light having a second intensity different from the first intensity. In one example, yellow light transmitted through the aperture of an electrochromic window in its darkest tinted state produces a blue light projection on the top surface of a table in a room. The light transmitted through the electrochromic window has a higher intensity than the ambient light illuminating the table top. Before the artificial light is activated, there is an intensity contrast between the blue light reflected from the lightcast on the table in the first portion of the table area illuminated by the ambient light in the room and the adjacent second portion. Subsequently, an artificial light source providing red and yellow light is activated to illuminate the table top. The tabletop reflects light from the blue light projection and red and yellow light from the artificial light source to reflect blue, red and yellow light from the first portion. The tabletop also reflects red and yellow light in a second portion illuminated primarily by artificial light sources. Red and yellow light from artificial lighting can shift or "wash out" the contrast between the light reflected from the first and second portions. picture 1A-1Cdepicts the room according to the implementation 150Schematic diagram of the perspective view of the room with the exterior of the building and the room 150Tinable windows in vertical walls between interiors 160. tintable windows 160In the darkened shaded state as shown.

Certain embodiments relate to control logic that determines and communicates new settings for building systems, such as the tint status of tintable windows, and settings for artificial lighting, wherein the new settings are determined by the control logic to reduce footprint, such as Contrast ratio in a table or other work surface). For example, the control logic may determine the setting of an adjustable artificial light source to tune it to wavelengths of red and yellow light and/or a brighter tinting level for a tintable window to reduce blue in light projection through the tinted window color depth. In this example, a combination of red and yellow light from an artificial light source is combined with blue light projected through a tinted window to produce red, yellow, and blue light, for example, with a spectral content closer to the natural light spectrum. This combination reduces the contrast in color and intensity between areas illuminated primarily by blue light projections and areas illuminated by artificial light sources. In some embodiments, the control logic adjusts the functionality of the building system based on a current contrast ratio in the occupied area, the current contrast ratio being determined based on feedback from the building system. For example, the contrast ratio in an occupied area may be determined based on the current illuminance in the occupied area as determined from one or more of: one or more sensors in the building (e.g., a video camera) , thermal sensors, etc.), the current setting and location of artificial lighting, etc. The illuminance and color of ambient light can be measured using a spectrometer such as, for example, the commercially available C-7000 spectromaster manufactured by Sekonic®. The control logic adjusts the functionality of the building systems to adjust the contrast ratio in the occupied area to an acceptable level. For example, building systems may be adjusted such that the contrast ratio is below an acceptable range or below a maximum limit. As another example, a building system can be tuned so that the contrast ratio is maintained within acceptable levels based on a look-up table of illuminance for artificial lighting that can be used to offset the The reflected light of light projection. Other considerations for controlling the tint state of one or more tintable windows and other building systems for the benefit of occupants and/or for the building alone will be set forth in other sections of this disclosure. For example, occupant health including circadian rhythm adjustment is a consideration discussed below. b. for glare control and / or other considerations for coloring configuration examples Examples of configurations for glare reduction are set forth in this subsection with reference in most cases to multi-zone tintable windows. It will be appreciated that these examples are also similarly applicable to a set of tintable windows or a combination of multi-zone windows and single sheet tintable windows. a) Glare Control by Daylighting In a particular glare reduction configuration, a multi-zone tintable window is controlled to place (remain in or transition to) the dimmed state of the tinted zones at locations within the tintable window that reduce occupants or In areas where glare may be located, simultaneously place the other tinted zones of the multi-zone tintable window in a lighter tinted state to allow ambient light in to eg reduce heating/illumination. This configuration can be used for Daylighting. As used herein, "daylighting" generally refers to the architectural strategy of using natural light to meet lighting requirements and potential color shifts while mitigating occupants' potential visual discomfort (such as, for example, caused by glare). Glare can come from direct sunlight falling on an occupant's workplace or into an occupant's eyes. This configuration and other daylighting examples set forth herein can provide a variety of benefits, including a reduction in blue from light in shaded areas due to changes in visual perception due to increased natural light in the room. As mentioned above, it will be appreciated that these examples also apply similarly to remaining in or transitioning to darken one or more tintable windows while the other tintable windows remain in a lighter tinted state to achieve daylighting. - Brighter shading in lower areas In this configuration, a multi-zone tintable window or group of tintable windows is controlled such that lower areas are brighter than other areas. In one example of this glare control configuration, the lower tinted zone of a multi-zone window in a vertical wall is controlled to be tinted brighter than one or more of the upper tinted windows in the multi-zone window. As another example of such a glare control configuration, a lower tintable window in a vertical wall is controlled to be tinted brighter than one or more upper tintable windows in the vertical wall. For example, at an angle where the sun is in a middle to high position in the sky and this lower area can be at a low position such that direct sunlight does not penetrate deeply into the room and thus does not create glare in the occupied area located near the window In the case of receiving sunlight, this control configuration can be used. In such a case, the lower area can be cleared or controlled in a way that allows the most light into the room and minimizes the heat load required to heat the room, while the middle and/or top areas can be darkened to Reduces glare on occupied areas. - Brighter shading in the top area In this configuration, a multi-zone tintable window or group of tintable windows is controlled such that the top areas are brighter than the lower areas. For example, a tinted zone (or tinted zones at the top) can be tinted brighter than one or more tinted zones of the multi-zone tintable window or the top region of the window. In another example, the top region of the window may have only a transparent substrate (no optically switchable device). As another example, an upper tintable window in a top region of a vertical wall is controlled to tint brighter than one or more other tintable windows in the vertical wall. In these instances, the brighter top area can function in a similar manner to a "transom window" by allowing a high degree of natural ambient light to enter the room while controlling glare near vertical walls. This and other lighting examples set forth herein can provide a variety of benefits, including a reduction in blue from light passing through tinted areas/windows due to changes in visual perception due to increased natural light in the room. picture 3For a multi-zone tintable window according to an embodiment 300A schematic diagram of this example, the multi-zone tintable window has five tinting zones. Multi-Zone Tinable Windows 300Between the interior and exterior of a building, in a room 350outside the vertical wall. Multi-Zone Tinable Windows 300included in the window 300The first colored region at the top of 302and in the first shaded area 302Four other colored areas below 304, 306, 308and 310. exist picture 3In the illustrated situation shown in , the sun is high in the sky. In this case, the shaded regions are controlled such that the first shaded region 302In the first colored state, that is, the brightest colored state (for example, decolorized or clear state), and the other colored regions 304, 306, 308and 310In a second colored state that is darker than the first colored state. For the shader control configuration shown, the first shader 302Allows natural light from the sun overhead to enter the room while preventing glare from direct sunlight projecting onto the occupied area with the table and occupants. Instead, passing through the first colored zone 302The direct sunlight casts glare (depicted by arrows) onto unoccupied areas of the room. Although five zones are used in the example shown here, other numbers and arrangements of colored zones may be used. In another example of this glare configuration, a multi-zone tintable window may include only a top transparent substrate portion without an optical device and a bottom portion with an optically switchable device having one or more tinting zones . For example, the multi-zone tintable window may have a monolithic electrochromic device with one or more tinting zones at the bottom portion of the window and a strip of light-emitting transparent substrate at the top. In another example of this glare configuration, and possibly other configurations for other purposes, according to one embodiment, a multi-zone tintable window includes one or more tinting zones, the one or more tinting zones being controllable area so that it has a color gradient from one side to the opposite side. In one instance, the top tinted region has a tinting gradient starting in a depigmented tinted state on one side and increasing tinting towards the opposite side. That is, there are no sudden changes in coloration as in physically separate regions where high contrast between regions may be distracting and unattractive to the end user. picture 4For a multi-zone tintable window according to an embodiment 460A schematic diagram of this example, the multi-zone tintable window has a tinting gradient. Multi-Zone Tinable Windows 460Located between the interior and exterior of a building, a room 450outside the vertical wall. Multi-Zone Tinable Windows 460included in the window 450The first colored region at the top of 462and in the first shaded area 462Second colored area below 464. In the diagram shown, the first colored area 462In a first colored state, the first colored state is the brightest colored state (e.g., a bleached state), and the second colored region 464In a second colored state that is darker than the first colored state. For the coloring shown, the first coloring zone 462Natural light from the overhead sun is allowed into the room while preventing glare from direct sunlight projecting onto the illustrated occupancy area with a table and seated occupants. through the first coloring zone 462The direct sunlight casts glare (indicated by the arrow) onto the unoccupied area at the rear of the room. In this particular instance, the multi-zone tintable window 460Also has shaded gradient areas 466, the colored gradient area includes a resistance area with a width. Shading Gradient Areas 466having the first colored area adjacent to the 462with the second colored area 464A shading gradient between shading states. That is, the shading gradient distance (or width) can be measured, for example, from the beginning of a region where %T begins to change, through and including the change in %T towards an adjacent region, where %T becomes constant in the second region where it ends. In one aspect, the width of the gradient portion is about 10”. In another aspect, the width of the gradient portion is in the range of 2” to 15”. In another aspect, the width of the gradient portion The width is in the range of 10" to 15". In one aspect, the width of the gradient portion is about 5". In one aspect, the width of the gradient portion is about 2”. In one aspect, the width of the gradient portion is about 15”. In one aspect, the width of the gradient portion is about 20”. In one aspect, the width of the gradient portion is about 20”. In one aspect, the width of the gradient portion is at least about 10”. In one aspect, the width of the gradient portion is at least about 16”. In one aspect, the width of the gradient portion covers the entire or substantially the entire width of the multi-zone tintable window. In such a case, the window may have a continuous gradient from light to dark across the entire window. In another aspect, the width of the gradient portion is less than 5 inches. - Intermediate area of lighter coloration While some instances of shading for tintable windows in a glare reduction configuration have the top or lower areas in a lighter tint state, other instances darken the top or lower areas to control glare while keeping the top area and One or more intermediate areas between the bottom areas become clear or leave them in a lighter state of pigment. In this case, a multi-zone tintable window or a group of tintable windows can be controlled such that the middle area of one or more tinted areas/windows is brighter than the other areas. For example, a multi-zone tintable window located very low or very high in a room may have a tint configuration that clears or places a middle zone or zones in a lighter tint state. As another example, a single multi-zone tintable window spanning multiple floors (eg, an open mezzanine or attic in a single room) can have a tinting configuration that clears a middle zone or zones. As another example, one or more tintable windows in the middle region of a vertical wall are controlled to be tinted brighter than other tintable windows in the vertical wall. picture 5for having three tintable windows according to an aspect 502, 504and 506the room 550schematic diagram. The room has a second mezzanine with two tables and a lower floor with a single table. tintable windows 502, 504and 506Arranged vertically and between the interior and exterior of the building, between rooms 550outside the vertical wall. In this illustration, the middle tintable window 504In a first tinting state (e.g., a de-tinting state), and other tintable windows 502and 506In a second shading state that is darker than the first shading state. For tinting shown, intermediate tintable windows 504Allows natural light from the sun to enter the room 550Place between occupied areas to reduce lighting/heating loads. This tinting also prevents glare from direct sunlight falling on occupied areas on the mezzanine and lower floors. While many examples of multi-zone tintable windows in glare-reducing configurations are described herein with respect to multiple full-width tinting zones positioned along the length of the window, other examples may include multiple tinted zones positioned along the width of the window. Full length tinted area. Alternatively, it is contemplated that a multi-zone tintable window may include rectangular tinting zones (digital design) corresponding to a two-dimensional array of locations across the length and width of the window. b) window with multiple panes In certain embodiments, a tintable window includes a plurality of panes in the form of, for example, an insulating glass unit (IGU) with spacers sealed between the panes. Another example is a laminated construction. Any of the tinting configurations shown and described herein with respect to the examples shown may be used for a single window or one or more windows of an IGU or laminate construction. In a glare-reducing tinting configuration, a tintable window includes a first tintable window combined with a second paired window having multiple tinting regions or a single tinting region. In this tinted configuration, the combined transmission of light passing through multiple windows can be used to provide a lower transmission than a single window. For example, the reduced transmittance level of two tintable windows through the region where the two windows are tinted to the darkest tinted state may be below 1% T. This reduced transmittance through areas of multiple tinted windows combined can be used to provide increased glare control in multi-zone tintable windows. That is, a transmission of less than 1% may be desired by some end users, for example, to further reduce glare. In such cases, tintable windows with multiple windows can be used to reduce transmission below 1% if desired. In one embodiment of this tinting configuration, a multi-zone tintable window is in the form of an IGU having multiple windows, each window having one or more tinting zones that can be tinted to reduce glare. At certain times of the year/day, the tinting of the upper area of the window is appropriate because the sun is at a certain height such that sunlight passing through the upper area is a glare passing through all parts of the window receiving sunlight The main reason. In other cases, other areas of the multi-zone tintable window may also benefit from this tinting. For example, the lower part may also benefit from this coloring. According to one aspect, the areas of a multi-zone window determined by the control method to be most suitable for tinting to reduce glare are those areas where occupants do not have good visual potential. In other words, it is desirable if the occupant can see out of the window when they are where they would normally be in the room, for example, to check weather conditions. In one example, the control method determines to maintain or transition the tint state of certain tinted areas to a darker tinted state to control glare on occupied areas as long as such areas of tinted areas do not block the occupant's view . In certain embodiments, a multi-zone tintable window in the form of an IGU is controlled to have a tinting state that balances glare control with reduced energy consumption. In one instance, the IGU's mating window may have one or more tinted regions designed to always or almost always reduce glare. While a mating window generally refers to any substrate of an IGU, in one instance, a mating window is a substrate of an IGU that does not have an optically switchable device (eg, an electrochromic device) thereon. c) Direction Control of Sunlight In one aspect, the paired windows in the IGU, or perhaps some other structure, can be designed to direct sunlight in the horizontal direction regardless of the relative height of the sun relative to the window position. The mechanism for directing light in the horizontal direction may include a set of very thin slats or louver structures inside or outside the IGU or associated with a mating window. In one example, a small mechanical shutter can be built into the electrically controllable area of the mating window to redirect light. As another example, a series of light pipes may reside outside or inside the IGU (the area between the windows) to direct sunlight in a substantially horizontal direction. picture 6for the room according to an embodiment 699Multi-zone tintable windows in the form of IGUs in vertical walls of 690A schematic diagram of an example. The IGU includes inner and outer EC windows and spacers (not shown) between the windows. The inner EC window includes a first tinted zone 693, the second coloring area 696and the third coloring area 697. Outer EC window includes first tinted zone 694and the second colored area 698. at the window 690the top part 692, the area between the windows 695There is a series of light pipes including reflective inner surfaces for transmitting light. In other embodiments, the region 695Light scattering elements, reflectors, diffusers, microshrouds (or similar MEMS devices) or the like may be included. In this shaded configuration, make the shaded area 693and 694Clear to allow sunlight to pass through while directing light or preventing light from hitting occupants and thus avoiding glare situations, while still allowing natural light to enter the space. In this configuration, sunlight passes through the 692Colored area at the outer surface of the EC window 694, transmitted through the light pipes, and transmitted through the colored area of the EC window in the clear state 693. In some cases, the light may be directed slightly to the back of the room as shown. For the shaded configuration shown, the window 690the top part 692Allows natural light from the sun at an elevated position to enter the room while preventing glare from direct sunlight on occupied areas with tables and occupants. In another embodiment, one or more windows of the IGU may have an area with a diffuse light source such that the light impinging on this area is diffused or scattered to eliminate potential glare on the occupied area. Diffusion or scattering can be achieved by applying a diffusing or light directing film to the area. These films contain many scattering centers or other channels to allow light in but at the same time reduce direct light on the occupied area. d) have non EC Membrane multi-zone window In certain embodiments, the tintable window includes an electrochromic device or other optically switchable device. In one embodiment, the tintable window includes an optically switchable device and a photovoltaic film. In another implementation, a tintable window includes an optically switchable device and a layer of thermochromic material and/or a layer of photochromic material. Some illustrations of tintable windows with thermochromic or photochromic materials can be found in U.S. Patent Application No. 12/2008, entitled "MULTI-PANE DYNAMIC WINDOW AND METHOD FOR MAKING SAME," filed June 25, 2008. 145,892 (now US Patent No. 8,514,476), which application is hereby incorporated by reference in its entirety. e) Other Examples of Lighting and Shading Configurations Certain aspects relate to tinting configurations having at least one tinting region or tintable window (daylighting tinting region/window) that remains in a decolorized tinted state. Daylighting tinting areas/windows allow natural light to enter the room while controlling glare/temperature in the room by tinting other tinting areas/windows. These aspects are aimed at motivation from occupants/buildings. First, daylight tinted areas/windows increase room light. That is, a darker tinting state may make the occupant feel that the room is too dark. Occupants may want to let more light into the room while still controlling glare when the sun is shining on the façade. Second, daylight tinting areas/windows can improve the color of light in a room. That is, a darker tinting state can make the light in the room appear colored (eg, blue). Occupants may want to maintain a more natural room color while tinting to control glare. Third, the lighting and tinting area/window can improve the vision through the window and the occupant's connection with the outside world. An occupant may want to recognize current weather or other outdoor conditions when the window is in a darker tint state. Fourth, daylight tinted areas/windows maintain glare/heat control. That is, other tinted areas/windows will be tinted to protect occupants from glare and heat from solar radiation. In certain aspects, the daylight tinting zones of the multi-zone window are wide enough to allow enough natural light to enter the room to reduce light color (eg, blue) in the room while still providing glare/heating control. In one aspect, the width of the daylighting tinted zone is about 5". In another aspect, the width of the daylighting tinted zone is less than 22". In another aspect, the width of the daylighting tinted region is between about 10" and 21". In one aspect, the width of the daylighting tinted zone is about 15". picture 7A first multi-zone tintable window showing aspects according to a daylighting tinting configuration 712left room 710and has a second multi-zone tintable window 732right side room 730. room on the left 710The first multi-zone tintable window 712Has two shaded zones above the level of the sill. room on the right 730The second multi-zone tintable window 732There are three shaded zones above the level of the sill.

In one case, the lower portion may be a transparent substrate without optically switchable devices. in two rooms 710, 730, the top shaded area is shown clear to allow daylight to pass through the shaded area into the room, which is the same as picture 3Similar to the transom window example shown in . First multi-zone tintable window with two tinting zones 712May have lower manufacturing and design complexity than three-zone windows. picture 8AIncluding one embodiment of the daylighting shader configuration according to the description in the room 800Plan and side (south elevation) views of a modeled building with several tintable multi-zone windows in . picture 8Binclude figure 8ARoom of the modeled building shown in 800perspective view. Each multi-zone window has two tinting zones, a first top tinting zone and a second middle tinting zone. The lower area is a transparent substrate without optically switchable devices. In the example shown, the upper tinted zone is brighter than the middle tinted zone to allow daylight to enter the room through the upper tinted zone. picture 9According to an embodiment, on June 21st, September 21st and December 21st from passing through picture 7Graph of the Daylight Glare Probability (DGP) for the 1st and 2nd row seats in the room for the multi-zone windows shown in .

Three zones provide more coloring options than two zones. Lower vision can only be sometimes tinted to slightly reduce glare but not affect light levels. picture 13Diagram showing a simulation of two views of a room with multi-zone tintable windows with daylighting tinting zones with a width of 15". picture 14Graph showing green-blue tinting and brightness in a simulated room with a daylighting tinting zone of width 5". The first 5" of the daylighting zone's width results in the largest incremental difference in room color. One embodiment is a method of providing daylight to a room having a tintable window between the room space and the exterior of the room, the method comprising allowing at least 5" of the length of the window to be untinted while allowing less tinting of the remainder of the length of the tintable window. 5% of the solar spectrum is transmitted through it. III. controller In some embodiments, one or more controllers may provide power or send other control signals to building systems to control the functions of those building systems. In some cases, for example, the controller may power one or more electrochromic devices of the tintable window. The controllers described herein are not limited to those controllers having the function of powering a device (or devices) with which they are associated for control. That is, the power supply can be separate from the controller, where the controller has its own power supply and directs the application of power to the device(s) from an independent power supply. However, it is convenient to include a power supply with the controller and configure the controller to directly power the device because it eliminates the need for separate wiring for powering the device. In some cases, a controller is a stand-alone controller configured to control the function of a single system, such as an electrochromic window or region of an electrochromic window or a plurality of electrochromic devices, and There is no need to integrate the controller into the building control network or building management system (BMS). In other cases, as further described in this subsection, the controller is integrated into the building control network or BMS. a.

In one instance, the microprocessor 1555PWM can be indicated 1560A voltage and/or current is applied to the electrochromic device of the window to switch it to any of four or more different colored states. In one instance, the electrochromic device is switchable to at least eight different coloration levels set forth as: 0 (brightest), 5, 10, 15, 20, 25, 30, and 35 (darkest). These tinting levels may correspond linearly to values of visual transmittance and solar heat gain coefficient (SHGC) of light transmitted through the electrochromic window. For example, using the above eight shading levels, the brightest shading level 0 may correspond to a SHGC value of 0.80, shading level 5 may correspond to an SHGC value of 0.70, shading level 10 may correspond to a SHGC value of 0.60, and shading level 15 may correspond to SHGC For a value of 0.50, a shading level of 20 may correspond to a SHGC value of 0.40, a shading level of 25 may correspond to an SHGC value of 0.30, a shading level of 30 may correspond to a SHGC value of 0.20, and a shading level of 35 (darkest) may correspond to a SHGC value of 0.10. As will be discussed below, light transmitted through a tinted window can impart color in a room. The depth of color will depend on the coloring grade. In some cases, the controller controls one or more tintable windows, such as electrochromic windows. In one instance, at least one or all of the electrochromic devices of the electrochromic window are solid state and inorganic electrochromic devices. In one instance, the electrochromic window is a multipane electrochromic window as set forth in U.S. Patent Application Serial No. 12/851,514 (now U.S. Patent No. 8,705,162), filed August 5, 2010, and entitled "Multipane Electrochromic Windows." state electrochromic window, which application is hereby incorporated by reference in its entirety. controller 1550or with the controller 1550The communicating master controller can employ control logic to determine control levels based on various data. controller 1550PWM can be indicated 1560A voltage and/or current is applied to or otherwise a control signal is sent to one or more devices based on the determined control level. b. building management system (BMS) The controller described in this article is suitable for integration with a building management system (BMS). BMS is a computer-based control system installed in a building to monitor and control the building's mechanical and electrical equipment, such as heating, ventilation and air conditioning systems (also known as "HVAC systems"), lighting systems, electrical systems (eg, wireless power systems), window systems (such as one or more zones of tintable windows), conveyance systems (such as elevator systems), emergency systems (such as fire protection systems), security systems, and other building systems. A BMS consists of hardware (including interconnects via communication channels to one or more computers) and associated Software composition. For example, a BMS can be implemented using an area network such as Ethernet. The software can be based on, for example, Internet protocols and/or open standards. One example is software from Tridium, Inc., located in Richmond, Virginia. One communication protocol commonly used for BMSs is BACnet (Building Automation and Control Network). BMSs are most common in large buildings and are typically used at least to control environmental conditions within the building. For example, a BMS can control temperature, brightness level, color temperature, contrast ratio, sound level or other sound quality, air quality (such as carbon dioxide level and/or particulate matter level), humidity level, and other conditions within a building. Typically, there are many mechanical devices controlled by the BMS, such as heaters, air conditioners, blowers, vents, and the like. To control the building environment, the BMS can turn on and off or otherwise control these devices in the building system to specific levels. A core function of a typical modern BMS is to maintain a comfortable environment (eg, visual comfort, thermal comfort, acoustic comfort, air quality, etc.) for building occupants while minimizing energy costs/demand. Therefore, modern BMSs are not only used for monitoring and control, but also for optimizing the cooperation between various systems, for example, to save energy and reduce building operating costs. picture 16Draw BMS 1600A schematic diagram of an embodiment, the BMS and the building 1601communicate (wireless or wired) and manage many systems, including security systems 1632, Heating/ventilation/air conditioning (HVAC) system 1634,Lighting system 1636,Power Systems 1642, elevators or other conveyor systems 1644, fire or other emergency systems 1645, window systems associated with tintable windows 1650and the like. security system 1632May include magnetic card access, turnstiles, solenoid actuated door locks, surveillance cameras and other asset or occupant locator devices, burglar alarms, metal detectors and the like. Fire or other emergency systems 1645May include alarm and fire suppression systems including plumbing controls. Lighting system 1636May include interior lighting, exterior lighting, emergency siren lights, emergency exit signs and emergency floor evacuation lighting. Power Systems 1642May include main power sources, backup generators, uninterruptible power supply system (UPS) grids, power generation systems such as photovoltaic power systems, and the like. In other embodiments, the BMS can manage other combinations of building systems. exist picture 16In the illustrated example shown in the BMS 1600main window controller 3202Send control signals to control the window system 1650. In this instance, the main window controller 3202Decentralized network shown as controllers including main network controller 1603, intermediate network controller 1605aand 1605bend-or-leaf controller 1610. end or leaf controller 1610can be similar to picture 15Window Controller 1550, relative to picture 19Window Controller 1940or relative to picture 20Window Controller 790. In one instance, the main network controller 1603Accessible to BMS 1600, and the building 1601Each floor or other area can have an intermediate network controller 1605aand 1605bone of these, and each tintable window or zone of tintable windows has its own terminal controller 1610 .In this instance, the end or leaf controller 1610each of which controls the building 1601Specific tintable windows or specific areas of tintable windows .end or leaf controller 1610Each of these can be in a separate location from the tintable window it controls, or can be integrated into the tintable window. For simplicity, only the buildings 1601The ten tintable windows are shown by the main window controller 3202control. In a typical situation, there may be a large number of tintable windows in a building with the main window controller 3202control. main window controller 3202There is no need for a decentralized network of window controllers. For example, as set forth above, a single end controller controlling the function of a single tintable window or a single zone of a tintable window also falls within the scope of the embodiments disclosed herein. In one aspect, the BMS or another controller receives sensor data from one or more sensors at the building via a communication network. For exterior sensors, a building may include exterior sensors on the roof of the building. Alternatively, the building may include exterior sensors associated with each exterior window or exterior sensors on each side of the building. Exterior sensors on each side of the building can track the irradiance on the sides of the building as the sun changes position throughout the day. As another example, a multi-sensor device with multiple sensors such as light sensors, infrared sensors, ambient temperature sensors, and others may be located at a building, for example, on a rooftop superior. Additionally or alternatively, the BMS may receive feedback data from other building systems. In one instance, the BMS may receive information about the presence and location of occupants in the building. By combining data from various building systems, a BMS can provide, for example, enhanced: 1) environmental control, 2) energy savings, 3) security, 4) flexibility in control options, 5) attribution to other Increased reliability and useful life of other systems due to less dependence of the system and thus less maintenance on other systems, 6) information availability and diagnostics, 7) efficient use of personnel and higher productivity from personnel, and the like various combinations of situations, since the systems can be controlled automatically. Building systems can sometimes operate on a daily, monthly, quarterly or yearly schedule. For example, lighting control systems, window systems, HVAC, and security systems can operate on a 24-hour schedule that takes into account when people are in the building during the workday. At night, the building can enter an energy saving mode, and during the day, the system can operate in a manner that minimizes the building's energy consumption while providing occupant comfort. As another example, the systems may be turned off or put into an energy saving mode during the holidays. Scheduling information can be combined with geographic information. Geographical information may include the latitude and longitude of a building. Geographical information may also include information about the direction each side of a building is facing.

An instance of a window controller for independently controlling multiple shaded areas In certain aspects, a single window controller or multiple window controllers can be used to independently control multiple zones of a single electrochromic device of a multi-zone tintable window or multiple tintable windows in a zone. In a first design, a single window controller is in electrical communication with multiple voltage regulators. In a second design, a master window controller is in electrical communication with multiple sub-controllers. In some cases, each multi-zone tintable window includes a memory, chip, or card that stores information about the window, including physical characteristics, production information (date, location, fabrication parameters, batch number, etc.) and the like. The memory, chip or card may or may not be part of the onboard window controller, eg, in a wire harness, pigtail and/or connector to the window controller. Described herein is a window controller that controls a multi-zone tintable window, whether on or as part of the window. U.S. Patent Application 13/049,756, filed March 16, 2011, entitled "MULTIPURPOSE CONTROLLER FOR MULTISTATE WINDOWS" and U.S. Patent Application, filed November 24, 2015, entitled "SELF-CONTAINED EC IGU" Additional information that may be included in memory is set forth in 14/951,410, both applications incorporated herein by reference for all purposes. - controller design 1 As mentioned above, according to a first design, a window controller is connected to the voltage regulators it controls. Each voltage regulator is in electrical communication with one of the colored zones. In one embodiment, the voltage regulators are onboard, ie part of the window assembly, eg in the secondary seal of the insulating glass unit. These voltage regulators may be physically separate from the controller, or be part of the controller, whether the controller is onboard or separate from the window. A window controller is in electrical communication with each voltage regulator to be able to independently instruct each voltage regulator to deliver voltage to its own tinting zone. Each voltage regulator delivers current to only one of the two bus bars in a particular colored region. This design involves multiple voltage regulators, one for each shaded zone, and all voltage regulators are collectively controlled by a single window controller via a communication bus (not shown). picture 19For this first design there are five (5) voltage regulators connected to the 1945window controller 1940A schematic diagram of the control system. Each voltage regulator 1945electrically connected to the window 1950the corresponding coloring area 1952one of the bus bars and is electrically connected to the window controller 1940. In this instance, the window controller 1940Indicates each voltage regulator 1945independently to its own colored area 1952delivery voltage. Each voltage regulator 1945color it 1952Only one of the two bus bars above delivers current. In this way, each district 1952Can be compared to other areas 1952Color independently. Another structural feature of this first design is that each of the voltage regulators is directed to or connected to only one of the bus bars in a respective zone of the multi-zone electrochromic device. The bus bars in the zones opposite the voltage regulated bus bars all receive the same voltage from the window controller. This presents a challenge if one of the colored regions needs to be driven in the opposite direction than the other regions because if the voltage applied to the other region does not coincide with such reversed polarity, then the polarity on the two bus bars will not work. reverse. In this design, each voltage regulator is a simple design with logic for applying voltage as directed by the window controller (eg, instructions stored on memory and retrieved for execution by the processor) . The local window controllers include logic with instructions for enforcing the rules, including: 1) communicating with higher level window controllers, 2) reducing power if necessary, 3) and The actual voltage applied to each. As one example of communicating with a higher-level window controller, a local window controller may receive instructions to place each of the individual regions in a respective tinting state. The window controller can then interpret this information and decide how best to achieve this result by applying the appropriate drive voltage, hold time, ramp profile, hold voltage, etc. to drive the transition. In U.S. Patent Application 13/449,248, filed April 17, 2012, and titled "CONTROLLER FOR OPTICALLY-SWITCHABLE WINDOWS" Details of control instructions for driving transitions in optically switchable windows are set forth in patent application 13/449,251, both of which are hereby incorporated by reference in their entirety. - controller design 2 In a second design, separate sub-controllers are used to control each of the shaded regions. In this design, the sub-controllers receive overall shading instructions from the main window controller. For example, the master (superior) window controller can send a signal with shading instructions to the sub-controllers to drive a particular shading region to transition to a new shading state. The sub-controller includes a memory that includes control instructions for driving transitions, including instructions for determining appropriate driving voltages, hold times, ramp curves, etc. required for driving transitions. The master window controller for a multi-zone window communicates with higher level control entities on the control network, the master window controller is also used to reduce the power from the power supply to an appropriate level for the sub-controllers to perform their functions. In such a design, each sub-controller has a lead to each bus bar of the respective colored zone it is responsible for. In this way, the polarity on one pair of bus bars for each zone can be independently controlled. If one of the colored zones needs to be driven at the opposite polarity than the other zone, by this design the polarity on the two bus bars can be reversed. This is an advantage over the first design because each zone can be colored or cleared independently. picture 20For connection to five sub-controllers (SWC) according to this second design 2070Schematic diagram of a single window controller. per sub-controller 2070has leads to the corresponding shaded area 2062The two leads of the bus bar. In this example, the SWC 2070 is connected to the main window controller 2080A SWC at the end of a chain of SWCs 2070 2070electrically connected in series. In this instance, the window controller 2080sub-controller 2070Sends a signal with a shader command to drive its associated shader 2062change. d. Photovoltaic power In certain embodiments, a tintable window (eg, an electrochromic window) includes a photovoltaic (PV) film or other light harvesting device. The light harvesting device harvests energy and converts solar energy to power window controllers and/or other window devices or for storage in batteries. e. Airborne window controller In some aspects, a tintable window has a window controller on the window. Details of an example of an airborne window controller are set forth in U.S. Patent Application Serial No. 14/951,410, filed November 24, 2015, entitled "SELF-CONTAINTED EC IGU," which application is hereby incorporated by reference in its entirety. enter. F. wireless power supply According to one aspect, the multi-zone window may be powered wirelessly, eg, via radio frequency, magnetic induction, laser, microwave energy, or the like. Details regarding components of wireless powered windows can be found in International PCT Application PCT/US17/52798, filed September 21, 2017, entitled "WIRELESS POWERED ELECTROCHROMIC WINDOWS," which application is hereby incorporated by reference in its entirety . In one aspect, a multi-zone tintable window includes a radio frequency (RF) antenna that converts RF energy into an electrical potential for powering transitions of one or more tinting zones in the multi-zone tintable window. The RF antenna can be located in the frame of the multi-zone window or in another structure such as a spacer between insulating glass units. For example, an RF antenna may be located in a spacer between insulating glass units having multiple windows, at least one of which includes a multi-zone electrochromic device. The RF antenna receives RF signals from the RF transmitter. In one case, an RF transmitter provides RF signals to multiple RF antennas. Details regarding examples of antennas are set forth in PCT application PCT/US15/62387, entitled "WINDOW ANTENNAS," filed November 24, 2015, which application is hereby incorporated by reference in its entirety. IV. Used to control tintable windows and / or other building system functions control logic In some implementations, the control logic used to determine shading decisions for groups (regions) of windows may be similar to the control logic used to determine shading decisions for multiple shading regions within a window or for individual windows within a group of windows to operate. That is, the control logic for multiple windows determines the tinting state of each window based on the position and orientation of that window. The control logic for multiple regions of a window will determine the shaded state of each region of the window based on the location and orientation of that region. An example of control logic for determining tinting decisions for multiple windows and transitioning the windows to the determined tinting state can be found in the PCT application titled "CONTROL METHOD FOR TINTABLE WINDOWS" filed on May 5, 2015 PCT/US15/29675, which application is hereby incorporated by reference in its entirety. In certain aspects, as set forth herein, certain operations of this control logic may be adapted to determine shading decisions for multiple shading regions and to power transitions in accordance with those shading decisions. In some aspects, the control logic may be adapted to address visual transitions of coloring within a particular colored region and/or between adjacent colored regions. For example, the control logic may include logic to determine certain shading states that produce strong contrast between different shading states in different regions or diffuse blending of colors between regions (e.g., using Resistive Area Technology). As discussed above, resistive regions between adjacent colored regions (rather than physical bifurcations) can be used to create coloring gradients between adjacent regions. This gradient of coloring generally exists across the width of the resistive area, and thus the smoother the visual transition, the greater the width of the resistive area. The control logic may be adapted to account for coloring gradients in the resistive region and/or may be adapted to apply gradient voltages along the length of the bus bars of the colored region to create a coloring gradient within the colored region (or monolithic EC device film). In one example, the bus bar can be tapered to apply a gradient voltage along the length and create a color gradient along the length. In another aspect, the control logic may be adapted to control a window having multiple tinted zones to determine a tinting state that will blend colors across the multiple zones. In one aspect, the control logic may be adapted to control the tinting state of a series of adjacent regions so that the transition from a region that needs to be particularly dark to a region that needs to be particularly clear is not abrupt. Another modification of the control logic may involve the ability to apply considerations associated with additional features of multi-zone windows in addition to common considerations such as glare control, views, natural lighting, occupant thermal comfort, building energy management, etc. Individual routines (eg, modules other than modules A-D of PCT application PCT/US15/29675, which sets forth aspects of Intelligence® as set forth above). For example, if light harvesting is the motive, additional modules may have to be built into the control logic to account for this additional consideration. In some cases, the order in which the functionality for addressing this additional feature or functionality of the shader is placed in the processing pipeline for common considerations may not matter. For example, the Intelligence® module does not necessarily need to operate in the following order in a situation: A à B à C à D. It will be appreciated that it may be the case that, in other cases, the order in which the modules are executed is not important. The control logic can also be adjusted to account for highly localized glare control across multiple zones. This situation can be addressed, for example, by modifications to module A of the control logic described in more detail in PCT application PCT/US15/29675. Different designs of window controllers that can power tinting transitions of multiple tinting zones of one or more multi-zone tintable windows are set forth above. In some aspects, a shaded region may have two shaded states: a first merged shaded state and a second darkened shaded state. In other aspects, a colored region can have four colored states. In other aspects, a colored area may have more than four colored states. a. for multiple shaded areas / Example of window tinting control logic picture twenty oneIncluded to illustrate the method according to the embodiment 2100is a flowchart showing operations for making shading decisions for multiple shading regions/windows. Such control logic may be used to determine tinting decisions for multiple windows and/or multiple shaded regions in one or more tintable windows, or combinations thereof. Instructions for this control logic are stored in memory and can be accessed by, for example, a window controller (such as is specifically referred to herein with respect to picture 19and picture 20window controller shown and described) to fetch and execute. The control logic includes two instructions for making the shading decisions shown in the flowchart to determine shading levels for a plurality of shading regions/windows. The control logic also includes instructions for independently controlling the tinting regions/windows to transition to the determined tinting levels. In certain aspects, operations of this control logic may be adapted to determine shading decisions to implement the shading configurations set forth herein. in operation 2110, calculated at the latitude and longitude coordinates of the window and at a specific time t _i The date of the hour and the position of the sun at the time of day. The latitude and longitude coordinates may be input from a configuration file. The date and time of day may be based on the current time provided by the timer. in operation 2120, computed in the operation 2110The amount of direct sunlight transmitted into the room through each of these zones/windows at a particular moment of use in based on operating 2110The amount of sunlight (eg penetration depth) is calculated from the position of the sun calculated in and the configuration of each zone/window. The zone/window configuration includes information such as the location of the window, the size of the window, the orientation (ie, facing direction) of the window, and details of any external occlusions. The zone/window configuration information is input from a configuration file associated with the zone/window. in operation 2130, to determine the irradiance level in the room. In some cases, an irradiance level is calculated based on clear sky conditions to determine clear sky irradiance. The clear sky irradiance level is determined based on the window orientation from the configuration file and based on the latitude and longitude of the building. These calculations can also be based on operating 2110The time and date of the day at the specific moment used in . Publicly available software such as the RADIANCE program, which is an open source program, may provide calculations for determining clear sky irradiance. Additionally, the irradiance level may be based on one or more sensor readings. For example, a light sensor in a room may take periodic readings to determine the actual irradiance in the room. in operation 2140, the control logic determines whether the room is occupied. The control logic may base its decisions on one or more types of information including, for example, scheduling information, occupancy sensor data, asset tracking information, picture twenty threeshown in ) from the user's activation data, etc. For example, control logic may determine that a room is occupied if the scheduling information indicates that an occupant is likely to be in the room, such as during typical business hours. As another example, if the schedule information indicates a holiday/weekend, the control logic may determine that the room is not occupied. As another example, control logic may determine that a room is occupied based on readings from occupancy sensors. In another example, the control logic may determine that a room is occupied if an occupant has entered information indicating occupancy at the manual control panel of the wall unit or remote control. In another example, the control logic may determine that a room is occupied (occupied) based on information received from an asset tracking device, such as an RFID tag. In this example, the occupants themselves are not tracked. By including occupancy sensors in the room with devices on the occupant's property or with systems such as Bluetooth Low Energy (BLE) that work with occupancy sensors, the control logic can determine whether the room is occupied. If in operation 2140If the room is determined to be unoccupied, the control logic selects for each zone/window a shading level that prioritizes energy control for heating/cooling the building (operating 2150). In some cases, other factors, such as safety or other safety concerns, may be considered when selecting a tint grade. use in operation 2140The coloring level of the middle judgment changes the area/window. Control logic then returns to the operating 2110, 2120and 2130, which is usually done periodically. If in operation 2140If it is determined that the room is occupied, then the control logic determines whether the user has selected the mode (operation 2160) or whether to select a mode for a particular occupant based on an occupancy profile. For example, a user (e.g., occupant or building operator) can click on a remote control or wall unit (such as picture twenty threeSelect the mode at the user interface shown in ). In some cases, the GUI may have buttons (eg, icons) designed to select a mode, eg, a lighting icon. Some examples of modes include: "Daylight Mode", "Uniform Mode", "Health Mode", "Emergency Mode" which are user defined modes. For example, a user can define "User 1 - Mode 1" with a specific shader configuration. If in operation 2160If it is determined that the user has selected a mode, the control logic selects a tinting level for each region/window based on the mode (operation 2170). For example, if Daylighting Mode is turned on, the shading level may be determined based on the following factors in the following order of priority: avoiding glare and allowing natural light to enter the room through the daylighting area. use in operation 2160The shading level selected in causes the area/window to change. Control logic then returns to the operating 2110, 2120and 2130, which is usually done periodically. In some cases, the three-dimensional projection of sunlight through each zone/window is calculated as the amount of direct sunlight transmitted into the room and a determination is made as to whether glare conditions exist in the room with that zone/window. hereinafter relative to picture 24A, picture 24Band picture 24CLet's discuss the discussion of light projection and the determination of glare conditions based on light projection. If in operation 2160If it is determined that the user has not selected a mode, the control logic selects a tinting level for each zone/window based on factors in the following order of priority: 1) glare control, 2) energy control, and 3) daylighting (operating 2180). In some cases, other secondary factors may also be considered in the selection of shading grades, including one or more of the following: time delay to prevent rapid transitions, color rendering, gradation of shading, based on historical data Feedback, occupants' viewing of the external environment and light collection. For example, when an occupant is in their usual location in a room, the occupant may wish to look out of a window, for example, to check weather conditions. If the occupant's view of the exterior environment is taken into account when making tinting decisions, the control logic may determine that while a dimmed tint state for a particular tinted area/window will avoid glare, a lower tint level will be used to provide greater visibility to the exterior environment. to see more clearly. In one embodiment, the three-dimensional projection of sunlight through each zone/window is calculated to determine the amount of direct sunlight transmitted into the room and to determine whether glare conditions exist in the room with that zone/window. hereinafter relative to picture 24A, picture 24Band picture 24CLet's discuss the discussion of light projection and the determination of glare conditions based on light projection. in operation 2180, in order to determine the suitability for operation 2120The tinting level for the amount of glare determined in the control logic can use an occupancy lookup table to 2120The amount of glare calculated in and the acceptance angle of the area/window are used to select the appropriate tinting level for the area/window. Space type and occupancy lookup tables are provided as input from a window-specific configuration file. Instances of the occupancy lookup table have different shading levels for different combinations of glare amounts and space types. For example, an occupancy lookup table may have eight (8) tinting levels including 0 (brightest), 5, 10, 15, 20, 25, 30, and 35 (brightest). The brightest shading level 0 corresponds to a SHGC value of 0.80, shading level 5 corresponds to a SHGC value of 0.70, shading level 10 corresponds to a SHGC value of 0.60, shading level 15 corresponds to a SHGC value of 0.50, shading level 20 corresponds to a SHGC value of 0.40, and shading level 25 A shading level of 30 corresponds to an SHGC value of 0.20, and a shading level of 35 (darkest) corresponds to an SHGC value of 0.10, corresponding to a SHGC value of 0.30. In this example, the occupancy lookup table has three space types: Desk 1, Desk 2, and Foyer, and six glare amounts (eg, the penetration depth of sunlight into the room through the zone/window). The tinting grade for table 1 closer to the window is higher than the tinting grade for table 2 farther from the window to prevent glare when the table is closer to the window. An illustrated example of such an occupancy lookup table can be found in PCT/US15/29675, filed May 5, 2015, and entitled "CONTROL METHOD FOR TINTABLE WINDOWS." In one embodiment, the control logic may be based on operating 2130The irradiance level determined in the middle is reduced based on the operating 2120The coloring level of the glare judgment in the medium judgment. For example, the control logic may receive sensor readings of irradiance indicating the presence of cloudy conditions. In such a case, the control logic may reduce the tinting level of the zone/window determined to be associated with a glare condition. in operation 2180, the control logic then determines whether to change the selected tinting level appropriate to the amount of glare based on the second priority, ie, energy control in the building. For example, if the outside temperature is extremely high such that the cooling load is high, the control logic may increase the tinting level in one or more zones/windows to reduce the cooling load. As another example, if the outside temperature is extremely cold, the control logic may reduce the tint level in one or more zones/windows while maintaining a dimmed tint state in zones/windows that would otherwise cause glare on the occupied area. The control logic then determines whether to change the tinting level based on the third priority, daylighting, while taking into account energy control in the building and maintaining darkened tinting in areas/windows that would otherwise cause glare on occupied areas state. use in operation 2180The coloring level of the middle judgment changes the area/window. Control logic then returns to the operating 2110, 2120and 2130, which is usually done periodically. b. Factors used to improve occupant health According to some aspects, the control logic is designed to control the tinting of tintable windows and other building system functions by maintaining visual comfort, thermal comfort, acoustic comfort, air quality and Other comfort factors to improve occupant health. For example, the control logic in question can be controlled by avoiding glare at the occupant's location or possible location, maintaining a brightness level and color temperature associated with the occupant's visual comfort, by adjusting natural lighting, and/or by adjusting window The tinting and associated light color in the room to minimize the contrast ratio in the room to maintain visual comfort. Other techniques for avoiding glare are discussed below. Additionally or alternatively, the control logic may control the rate of transitions between shading states. Additionally, certain shading configurations may control shading gradients between adjacent shading regions in different shading states and/or within a particular shading. Some configurations for controlling coloring gradients between adjacent regions and within specific regions are discussed above. Some configurations aimed at avoiding glare at the occupant's position or possible position, increasing natural lighting in the room and/or the color of the window and associated light color in the room are also discussed above. 1. Glare avoidance using passive or active manipulation of light In certain embodiments, a multi-zone window includes one or more technologies for passive or active manipulation of light passing through the window to ensure no glare on occupied areas and control thermal loads while allowing continuous daylighting into the room. These techniques can work together with controlling the tinting of the multi-zone window. In one aspect, the window can have active or passive control of the direction of light entering the room. Some examples of such technologies include microshrouds, hexagonal lattices, light pipes, IR mirrors or IR reflectors, IR absorbing or IR reflecting films. In one example, the window is designed to ensure that light is directed in parallel as it enters the room by using microshrouds or hexagonal lattices or thin film coatings. These techniques can be used to allow natural light into buildings while avoiding glare, control heat and allow manipulation of light, providing favorable color rendering using natural daylight. In one example, a multi-zone window in the form of an IGU has a light pipe in the area between two windows. The light pipes are in the area near the tinted areas of the windows. The two colored areas are in a clear state for continuous lighting to transmit the sunlight incident on the outer surface. In another aspect, a multi-zone window in the form of an IGU includes one or more IR mirrors or IR reflectors in the region between two windows of the IGU. In one example, the mirrors/reflectors are located in an area aligned with one or more tinted areas that can remain in a clear state to allow continuous lighting into the room when sunlight is incident on the exterior surface at that area . In another aspect, a multi-zone window with an electrochromic device includes an IR absorbing or IR reflecting film to control heat entering a building and has active or passive control of the direction of light entering a room. - miniature shield In embodiments with microshrouds, the microshrouds or the window can be hinged to adjust the direction of light entering the room. For example, the microshrouds can be hinged to orient them to direct light bouncing off the ceiling and/or remain parallel. In one example, the multi-zone window is circular and is rotatable (at least) in the plane of the wall it is installed in to collect light as the sun position and azimuth change, e.g. Direct light in the same direction. The circular window may additionally have controllably hinged micro-shutters to change its orientation to ensure proper glare-free lighting throughout the day. Some details of microshrouds and MEMS devices are set forth in U.S. Patent Application Serial No. 14/443,353, entitled "MULTI-PANE WINDOWS INCLUDING ELECTROCHROMIC DEVICES AND ELECTROMECHANICAL SYSTEMS DEVICES," filed May 15, 2015, which It is hereby incorporated by reference in its entirety. A multi-zone window with a micro-shading will typically be installed above a tintable window/zone without a micro-shading, and above the level of the occupant, to help ensure there is never any glare on the occupant. If the window has active or passive aiming of the incident light, the angle of the microshroud can be adjusted to modify the angle to ensure no glare even if it is placed below the height of the occupant. In some cases, multi-zone windows with technology for passive or active manipulation of light can be controlled based on input from cameras or sensors in the room, such as occupancy sensors. When coupled with cameras or sensors in the room, this configuration can use active targeting to optimally heat the room when desired. Additionally, coupled with internal active or passive reflective surfaces, the system can collect light and direct it to other areas of the building. For example, light pipes can be used to convey light to other areas or simply be directed by opening holes in the walls to allow light to penetrate deeper into the building. 2. Color rendering and modified color temperature The tinting of a tintable window can change the amount of light transmitted through the tintable window and the wavelength spectrum and associated color of the interior light transmitted into the room. Some of the coloring configurations described herein have the technology to provide a preferred spectral selection of incident light. These technologies can enhance lighting to balance the color displayed indoors with the amount of natural light in the appropriate wavelengths to improve visual comfort, circadian rhythm adjustment, and associated physiological responses. For example, a tintable window may include a filter layer that controls the transmission of natural sunlight through the window. These technologies can improve the color and spectrum of incident sunlight entering a room and the comfort, visual perception, mood and health of occupants. Some techniques can change the CCT (correlated color temperature) and CRI (color rendering index) of the light in the room so that the color of the incident light is closer to natural light. A shading configuration provides natural lighting and filtered light. These configurations can also use artificial lighting to enhance and/or adjust CCT and/or CRI. Other approaches provide only filtered light and artificial lighting to enhance and/or adjust CCT and/or CRI. - Use color balance to achieve optimal lighting for occupants As outlined above, the methods described require tinting in certain areas and not in others, e.g., certain areas of a multi-zone tintable window or certain windows in a group of tintable windows, for occupant Reduction of glare while allowing ambient light to enter, i.e., so-called "daylighting", daylighting uses natural light to meet lighting requirements and color shifts (color balance), e.g. unwanted from tintable windows of the space given to the occupants blue. In general, occupants prefer natural sunlight to artificial lighting from, for example, incandescent, light emitting diode (LED) or fluorescent lighting. However, with advancements in LED lighting technology, a greater range of lighting possibilities, wavelengths, frequencies, colors, intensity or lumen ranges, and the like are possible. Certain embodiments use LED lighting technology to offset blue or other unwanted colors in an occupant's space due to transmitted light from a tintable window. In certain embodiments, control of the tintable windows includes control of LED lighting to correct this perceived and manifested color to produce ambient lighting conditions that occupants prefer. These approaches can improve the color and spectrum of incident sunlight entering a room and occupants' comfort, visual perception, mood and well-being. Some methods change the CCT (correlated color temperature) and CRI (color rendering index) of the light in the room so that the color of the incident light is closer to natural light. In some embodiments, LED lighting is used to enhance daylighting from natural light sources, e.g., where the amount, angle, or other factors of natural light entering a room are such that the natural lighting is not sufficiently offset from filtered light passing through a tintable window when the color. For example, electrochromic windows can change the spectral bandwidth, color and amount of natural light entering a room. By providing better spectral selection of the incident light, we can provide enhanced lighting to balance the color of the interior appearance with the required amount of natural light in the appropriate frequency to ensure visual comfort and, for example, circadian rhythm adjustment and improved physiology reaction. In certain embodiments, LED lighting is used as a substitute for natural light in order to achieve daylighting; that is, when only filtered light through the tinted window is available, the LED lighting is adjusted to compensate for the unwanted light imparted by the tintable window. To the color. It may be the case, for example, that certain occupants require window elevations that are uniform in tinting, i.e. multi-zone windows, or that tinting some windows while not tinting others is undesirable from an aesthetic point of view of. In one embodiment, the color and light characteristics of filtered light from a window or group of windows that are uniformly tinted (that is, certain windows or areas are not used to allow daylight in to shift the color) are quantified. Measurements or calculations based on known filtering properties of the tintable window. Based on the obtained values, LED lighting is used to offset unwanted colors or other light characteristics in order to improve occupant comfort. Some methods change the CCT (correlated color temperature) and CRI (color rendering index) of the light in the room to make the ambient light color closer to the color of natural light. In these embodiments, incident light (with or without natural light) is modeled via predictive algorithms or by room sensors (e.g., on walls, e.g. picture twenty threeIncident light (with or without natural light) is measured directly in the described wall unit, or in one or more of the tintable windows that allow light to enter the space. In one example, LED lighting is used to maintain a higher color temperature when the tintable window is in a less tinted (less absorbing) state, and LED lighting is used when the tintable window is in a more tinted (more absorbing) state. lighting to impart a lower color temperature (eg, more yellowish) to maintain a CRI closer to that of natural lighting in the space. Additional aspects of these embodiments are set forth below in the "Circadian Rhythm Adjustment" and "Healthy Patterns" subsections of this specification. - Circadian Rhythm Adjustment In certain tinting configurations, the tinting is controlled (eg, by filters) to change the wavelength spectrum of incident light to the appropriate light wavelengths to adjust circadian rhythms and thus benefit occupants. In one technique, coloring is controlled (eg, by filters) to change the wavelength spectrum of incident light to an occupant's preferred appearing color. Such technology allows control of LED lighting or other lighting to correct this perceived and manifested color to better lighting conditions for occupants. By controlling the transmission of some amount of natural lighting at the appropriate wavelength/wavelengths, circadian rhythms can be adjusted, which can benefit the health and wellness of the occupants. In such configurations, the control logic may have operations to predict the amount and direction of solar radiation, or sensors in the room may measure the amount and direction of solar radiation. For example, an irradiance sensor located on a wall or window in a room may send a signal with periodic measurements to the window controller. In one instance, the sensor may have to be proven sufficiently sensitive (eg, in a healthcare setting)/tested and calibrated to ensure correct results. Alternatively, we can obtain this information from the lighting system. To provide circadian smart lighting, windows can have specific sensors with bandgap filters and time trackers to ensure that the window provides the correct spectrum of natural light required at specific times of the day. This can be provided by daylight passing through the windows and/or by enhanced interior lighting that has been requested to provide the correct amount of illumination of the appropriate wavelength. - " healthy model " Furthermore, the color of interior light may have an impact on the behavior of occupants in different spaces based on the function of the space. The control logic may have a separate logic module for controlling filtered natural light or enhanced interior lighting to benefit the mood and behavior of the occupants. The operation of this module may function differently depending on the function of the space in which the occupant is located in the room. In some cases, the user may be able to select "Health Mode" on the user control panel to control the lights in the room according to this mod designed to improve the mood and behavior of the occupants. In some cases, the control logic may be adapted to predict the wavelength and intensity of the external lighting and then combine this with the current shading level spectral characteristics and predict the spectral distribution of incident sunlight entering the room. The wavelength and intensity of exterior lighting can be predicted, for example, using a weather service and based on the sun angle calculated by a solar calculator. By including occupancy sensors in rooms via devices on the occupants or systems such as BLE that work with occupancy sensors, control logic can choose whether to control daylighting and windows relative to the occupancy profile. Alternatively, if the room has a camera capable of recording the brightness and spectrum in the room, the camera image can be used to determine if there is an occupant, where the occupant is, and what offset or offset to the interior light would be needed to correct for the EC filtered light. Change. This camera can also be calibrated to ensure that for the time of day and specific location the occupant gets the right amount of light spectrum to benefit their circadian rhythm. Alternatively, by using a large number of sensors in the ceiling or in each light, the sensor data can be used to verify occupants, occupancy of a particular location and color rendering of desired lighting and benefit to the occupant's circadian rhythm Just the right amount of spectrum. Coloring decisions based on health considerations are based on one or more factors, including: (1) lighting in the room with an appropriate wavelength spectrum to adjust the occupant's circadian rhythm; (3) provide an appropriate color rendering index for the interior light in the room based on a predetermined color appearance to correct the filtered light color of the EC IGU; (4) correlated color temperature for the interior light in the room based on Predetermining the amount of CCT to correct the filtered light color of the EC IGU that can be applied to improve the psychological effect of light in a given interior space; (5) Consider unique sensors that are proven to support lighting Appropriate spectral distribution to benefit occupants' circadian rhythms; and (6) lighting targets that change based on whether occupants are affected by lighting controlled by interior lighting or filtered light from an EC IGU . c. Example of control logic for controlling tinting of tintable windows In certain implementations, the control logic includes operations to determine and control tinting in a tintable window (eg, an electrochromic window) to account for occupant comfort and/or energy saving considerations. In some cases, the control logic includes multiple logic modules. The shading level determined by one logic module and/or other calculations are input to another logic module to calculate the final shading level determined by all modules. If an override is applied, the override value can be used as the final shading level. Once the control logic determines the final shading level, the control logic sends a control signal with shading instructions to transition the tintable window to the final shading level. An example of control logic with a logic module configured to determine the tinting level of tintable windows can be found in International PCT Application PCT/US15/, filed May 5, 2015 and entitled "CONTROL METHOD FOR TINTABLE WINDOWS" 29675, which application is hereby incorporated by reference in its entirety. Another example of control logic with a logic module configured to determine the tinting level of tintable windows can be found in the International PCT Application PCT/ In US 16/41344, this application is hereby incorporated by reference in its entirety. In some embodiments, the control logic uses one or more of three logic modules (also referred to herein as "Module A," "Module B," and "Module C") to determine the The tinting grade for tintable windows between the interior and exterior. Each control logic module may determine the shading level based on a future time. For example, the future time used in the computation may be a future time sufficient to allow the transition to complete after the shading instruction is received. In this example, the controller may send shading instructions at the current time, before the actual transition. Before the transition is complete, the window will transition to the desired tinting level at that time. Module A can be used to determine the level of tinting for occupant comfort based on direct sunlight passing through tintable windows onto occupied areas or areas of occupant activity. The shade level is determined based on the calculated penetration depth of direct sunlight entering the room at a particular moment and the type of space in the room (eg, table near window, hallway, etc.). In one example, the penetration depth at a future time is calculated to account for the time it takes for the window to transition to a new tinted state. Publicly available programs can be used to calculate the position of the sun based on the time of day, time of year, and latitude and longitude of buildings. The first module can be based on the geometry of the window (e.g., window size), its location and orientation in the room, any fins or other external shading outside the window, and the calculated position of the sun (e.g., for a particular time of day). The time and date of the direct sunlight angle) to calculate the penetration depth. Each space type is associated with different shade levels for occupant comfort. For example, if the activity is critical, such as doing office work at a desk or computer, and the desk is near a window, the desired shading level may be higher than when the desk is away from the window. As another example, if the activity is non-critical, such as activity in a hallway, the desired tinting level may be lower than that of the same space with a table. Input the coloring grade calculated by module A into module B. The control logic of module B can be used to determine the tinting level based on the irradiance transmitted through the window under clear sky conditions (also referred to as "clear sky irradiance"). Radiation can come from sunlight scattered by molecules and particles in the atmosphere. Clear sky irradiance can be calculated based on the latitude and longitude of the building, the day of the year and time of day, and the orientation of the windows using a program such as the open source program RADIANCE program. In one example, module B may be used to determine a tint grade that is darker than the tint grade input from module A and transmit less heat than calculated to be transmitted for a reference glass at maximum clear sky irradiance. The maximum clear-sky irradiance is the highest level of irradiance calculated for clear-sky conditions at all times. In one example, module C then uses the solar heat gain coefficient (base SHGC) of the reference glass and the calculated maximum clear sky irradiance to determine the tinting level. Module B gradually increases the shading level calculated in module A and takes the shading level such that the internal irradiance is less than or equal to the reference internal irradiance (base SHGC×maximum clear-sky irradiance). Input the coloring grade calculated in module B and the calculated clear sky irradiance into module C. The control logic in module C can be used to determine the tinting level based on the immediate external irradiance based on direct or reflected light illuminating the tintable window. This immediate external irradiance takes into account light that may be blocked by or reflected from objects such as buildings or weather conditions (eg, clouds) that were not accounted for in the clear sky calculations performed in module B. The real-time external irradiance may be calculated based on one or more of the following: measurements obtained by external sensors, weather forecast data received via a communication network, determined cloud conditions at buildings, and the like. In general, the control logic for module B will determine shader levels that darken (or not change) the shader levels determined by module A, and the control logic for module C will determine shader levels that darken (or not change) the shader levels determined by module A The shading level at which the shading level is brightened (or not changed). The control logic in module C can determine the internal irradiance in the room based on the external irradiance and the current tinting level of the tintable window. For example, Module C can use the following equation to determine the calculated interior irradiance based on the clear sky irradiance calculation: Calculated interior irradiance = Shading grade SHGC x Calculated clear sky irradiance. Module C can calculate instant internal irradiance based on external sensor readings or other external data using the following equation: Instant internal irradiance = Shading grade SHGC x irradiance reading. In one embodiment, module C uses the above equation to calculate the interior irradiance of a room when the tintable window has the tinting level determined in module B and then determines based on the tinting level from B that the interior irradiance is less than Or a tinting grade equal to the condition of the calculated internal irradiance. Module B and/or Module C can determine a tinting level that takes energy savings into account in addition to occupant comfort. These modules can determine the energy savings associated with a particular tinting level by comparing the performance of a tintable window at the determined tinting level to a baseline glass or other standard reference window. The purpose of using this reference window may be to ensure that the control logic complies with municipal building code requirements or other requirements for reference windows used in the building's location. Typically, municipalities use conventional low emissivity glass to define reference windows to control the amount of air conditioning load in buildings. As an example of how a reference window can be incorporated into the control logic, the logic can be designed such that the irradiance passing through a given tintable window is never greater than the maximum irradiance passing through the reference window as specified by the respective municipality. In disclosed embodiments, control logic may use the SHGC value of a tintable window at a particular shading level and the SHGC of a reference window to determine energy savings using that shading level. In general, the value of SHGC is the fraction of all wavelengths of incident light that is transmitted through the window. While a reference glass is set forth in many of the embodiments, other standard reference windows may be used. In general, the SHGC of a reference window (eg, reference glass) is a variable that can be different for different geographic locations and window orientations, and based on regulatory requirements specified by individual municipalities. Once modules A, B, and C determine the final shading level, the control logic may receive an override that causes the override value to be used as the final shading value. One type of override is a manual override by an occupant of the room who determines that a particular tinting level (override value) is desired. There may be situations where the manual override itself is overridden. Another example of an override is a high demand (or peak load) override associated with a facility requirement to reduce energy consumption in a building. Once the control logic determines the final shading level, the control logic sends a control signal with shading instructions to transition the tintable window to the final shading level. d. For adjusting artificial interior lighting and / or coloring control logic As mentioned above, the tinting of an electrochromic window or other tintable window can change the wavelength spectrum and associated color of light transmitted through the tinted window to manifest color in a room. For example, certain electrochromic windows in a darker tinted state can impart a blue color in a room. Certain techniques set forth herein relate to control logic for controlling artificial interior lighting to enhance the color appearing from the interior of one or more electrochromic or other tintable windows in a room. These techniques can be used to control the levels of color rendering index (CRI) and/or correlated color temperature (CCT) in a room interior to, for example, improve visual comfort, adjust circadian rhythms, and the like. CRI is a measure of the ability of interior lighting to accurately render all the colors of an object to the human eye. Usually, the CRI value is measured on a scale from 0 to 100%, wherein the higher the CRI value, the better the color rendering. CCT is a temperature measurement of the color characteristic of lighting in the visible spectrum. CCT value is usually measured in degrees Kelvin (K). In certain implementations, techniques involve control logic that determines a current value for the interior CRI of a room, and if the current value is not a desired value, sends a control signal to adjust artificial interior lighting and enhance interior lighting to reveal the desired interior CRI. Additionally or alternatively, certain implementations determine the current value of the interior CCT of the room and/or adjust interior lighting to reveal the desired interior CCT. In these techniques, based on input from exterior sensors located on the outside of the building, interior sensors located in the room, and/or one or more electrochromic windows between the interior of the room and the exterior of the building, Coloring status to determine the current value of the internal CRI/CCT. Some examples of the types of external sensors that can be implemented include infrared sensors, ambient temperature sensors, and visible light sensors. In implementations with one or more exterior sensors, the exterior sensors are positioned generally in contact with the environment outside the building having the room. In some cases, external sensors are located on the facade near the electrochromic window, for example, to determine the irradiance level at the window in order to determine the external CRI/CCT outside the window. In another case, external sensors may be located on the roof of a building. In other cases, external sensors may be located at different buildings. In some cases, external sensor data may be used to forecast weather conditions and communicate the forecast data to a controller that sends control signals to artificial interior lighting for adjustments and/or to electrochromic windows To transform coloring. An example of an arrangement of external sensors that may be used in a multi-sensor device is set forth in detail in US Patent Application 15/287,646, entitled "MULTI-SENSOR," which application is hereby incorporated by reference in its entirety. Such multi-sensor devices can be installed on the roof of a building. In one embodiment, the multi-sensor device comprises a radially oriented outward facing light sensor having different orientations, a vertically upward facing light sensor, one or more IR sensors and A ring of temperature sensors. In one example, readings from an IR sensor and a temperature sensor can be used to determine cloudiness conditions. Additionally or alternatively, irradiance readings from different radially oriented photosensors may be used to calculate irradiance values at orientations different from those of the photosensors. Using this technique, the external irradiance from a different radially oriented light sensor can be used to determine the external irradiance for a window in another orientation. One example of such technology is set forth in PCT Publication PCT/US15/52822, filed April 7, 2016, entitled "COMBI-SENSOR SYSTEMS," which application is hereby incorporated by reference in its entirety. Some examples of interior sensors that can be implemented with these technologies include visible light sensors, temperature sensors, and other sensors that can be used to calculate the interior CRI of a room and the CRI of the exterior of a window. Interior sensors may be located at various suitable locations within the room, such as, for example, at or near artificial interior lighting, at or near occupant activity areas such as table or conference table tops, walls, and the like. In addition, an example of a commercially available device for measuring CRI and which can be used as an internal sensor for measuring internal CRI or an external sensor for measuring external CRI is the CL-70F CRI manufactured by Konica Minolta® luminance meter. Another example is the C-700 SpectroMaster manufactured by Sekonic. These techniques can be used for various types of artificial interior lighting, including, for example, incandescent lighting, light emitting diodes (LEDs), and/or fluorescent lighting. A commercially available example of artificial interior lighting that can be used in these embodiments is Hue® manufactured by Phillips® ^tmPersonal wireless lighting system. Another commercially available example of artificial interior lighting that can be used is the Aurora Lighting Smarter Kit made by nanoleaf® ^tm. Below is a diagram showing four exemplary scenarios of combinations of inputs that may be used by the control logic to control an internal CRI in a room. While the control logic for these situations is described with reference to a single electrochromic window, it will be understood that the present disclosure is not limiting and that such control logic may be used in rooms with multiple electrochromic windows or other tintable windows. situation external sensor internal sensor Internal Color Rendering Index (CRI) control 1 no no Based on tinted state of glass only 2 no yes Using LED lighting to adjust CRI based on internal sensor readings 3 yes no Based on the external sensor readings and the tinting state of the glass, the internal CRI is determined based on the external CRI, which is transformed into an internal CRI adjusted to the desired CRI using LED lighting 4 yes yes Can be selected for #2, #3 or both (by user or algorithm) In the first case, the internal CRI is controlled based only on the tinting state of the electrochromic window. No input from any internal or external sensors is used to control the internal CRI. In one implementation, each tinting state of the electrochromic window is mapped to a particular internal CRI value or range of internal CRI values (eg, in a look-up table). These values can be calculated in advance, for example, by measuring the CRI values in various colored states of the product glass. The control logic determines the tint state of the electrochromic window mapped to the desired CRI value/range. For example, the darkest shading state (eg, 1% T) may map to an internal CRI value corresponding to appearing blue in the room. In this embodiment, control of the internal CRI value/range may not depend on knowledge of the light conditions outside the electrochromic window. It may depend, for example, on whether the room is occupied, more specifically whether the lights are on. The desired CRI can be preset as a user preference based on the tinted state of the glass. For example, when the tinting state is at a certain level and the lights in the room occupied by the user are on, the interior light can be automatically adjusted to provide a preset CRI. This lighting adjustment can be done after the tinted state of the glass is achieved, or the lighting can be changed dynamically during a change in the tinted state of the glass. In this mode there is no need to enter sensor readings because the CRI is not actively measured, but is preset in advance based on user preference based on measurements and/or calculations. External conditions are not measured (although related to internal CRI), ie, because the glass is in a particular state of tint, it is assumed that external lighting conditions warrant the glass being so tinted, and therefore the CRI is adjusted based solely on the state of tint of the glass. In some embodiments, sensor readings are used to enhance the accuracy of the adjustment of the CRI to a desired value. For example, in the second case, measurements from one or more interior sensors in the room are used to control the interior CRI value of the room. The internal CRI value is determined without using measurements from any external sensors or the tinting state of the electrochromic window. Because electrochromic glass transforms external light as it passes through the glass, external lighting conditions are irrelevant in this embodiment, and one or more internal sensors are used to determine internal lighting conditions and respond accordingly. Adjust internal lighting conditions to obtain proper/desired CRI. Occupancy sensors can be used with light sensors to enhance CRI adjustment. For example, if the room is not currently occupied, the CRI adjustment may be avoided or made a CRI adjustment that is sub-optimal for the occupants and, for example, more consistent with the energy savings of the lighting system. When a room is occupied, CRI adjustments using lighting can override potential energy saving settings in favor of an optimal CRI for the occupant. In one implementation, one or more interior sensors may be calibrated or designed to measure the interior CRI of a room. In another implementation, ranges of internal sensor measurements may be mapped to internal CRI values (or ranges), such as in a lookup table. Control logic determines in this example that the internal sensor measurement is within a particular range and determines the CRI value associated with that range. In this second scenario, artificial interior lighting is adjusted based on interior sensing measurements. Measurements from interior sensors control adjustments made to artificial interior lighting. In some embodiments, internal sensor measurements are used as input to adjust only the internal CRI to user preference to achieve desired results. In another embodiment, the control logic compares the measured internal CRI value to the proper/desired value and if there is a difference, the control signal adjusts the artificial interior lighting based on the difference to enhance the interior lighting in the room. In the third case, the desired internal CRI value for the room (also referred to herein as "internal CRI") is obtained using measurements from one or more external sensors and the tinting state. The control logic calculates or measures (eg, using a multi-sensor device) an extrinsic CRI (also referred to herein as "extrinsic CRI"). Based on the tinting state of the electrochromic glass, the control logic converts the external CRI to the internal CRI by calculating the internal CRI based on the external CRI and the known light absorption and color changing properties of the glass. The control logic then sends a signal to artificial lighting (eg, LED lighting) to tune to a better or custom CRI value in the room (logic makes this comparison if the calculated internal CRI is not already at the better level). In this third case, measurements from internal sensors are not used. Since the electrochromic glass transforms the external light when it passes through the tinted glass, the internal CRI can be calculated based on the measurement results of the external CRI and the tinted state of the glass. Interior lighting conditions are not required. External CRI may be based on measurements taken by one or more external sensors. In one implementation, the one or more exterior sensors may be calibrated or designed to measure exterior CRI near windows and/or generally near building areas. In another implementation, ranges of external sensor measurements may be mapped to external CRI values (or ranges), such as in a lookup table. The control logic uses the external CRI value and the tint state characteristic of the glass to obtain the internal CRI value and then adjusts it to match the desired value if it does not already match it. In one implementation, different combinations of shading states and external CRI values can be mapped to specific internal CRI values. For example, assuming that the curtain wall of windows is all in the same tinting state, one internal CRI can be obtained, but if one or more windows in the curtain wall are tinted to a different tinting state, a different internal CRI value is obtained and can be obtained by corresponding Change the interior lighting to adjust the interior CRI value. In one embodiment, the inner CRI is only adjusted based on a calculated value based on the state of the window and the measured outer CRI. In another embodiment, the control logic compares the calculated internal CRI value to the desired result. In another embodiment, the control logic compares the measured internal CRI value to the proper/desired value and if there is a difference, the control signal adjusts the artificial interior lighting based on the difference to enhance the interior lighting in the room. In a fourth scenario, the control logic uses user input to determine whether to control the room based on measurements from one or more external sensors and/or based on measurements from one or more internal sensors In-house CRI. That is, a combination of the second case and the third case, for example, based on user preference and/or the accuracy of the method (internal sensors, external sensors, or both), which may depend on internal and external CRI measurement accuracy (which may vary with lighting conditions and the accuracy or effectiveness of the sensor in those conditions (eg, cloudy conditions for external sensors)). If the user input selects that external sensors are to be used, the control logic uses measurements from one or more external sensors to determine the internal CRI in the room according to the third scenario set forth above. If the user input selects that internal sensors are to be used, the control logic uses measurements from one or more internal sensors to determine internal CRI according to the second scenario set forth above. The control logic then sends control signals to adjust the artificial interior lighting to enhance the interior lighting in the room to be at or near the desired interior CRI. In other embodiments, sensors are used to determine the external CRI, and thus a more accurate determination of the internal CRI can be made by calculation or by means of internal sensor measurements. The user selects a preference or algorithm based on preset criteria, whether or not using one or both of interior and exterior sensors to determine exterior and/or interior lighting conditions as input to determine an appropriate interior CRI. The importance of the fourth embodiment is that the sensors (internal and/or external) are more useful in some environmental conditions than in others. For example, it may be the case that when overcast conditions are dominant outside, the external sensors are less efficient to provide accurate data for input to the control logic, and only the internal sensors are used to determine and adjust the internal CRT more accurate. While these four scenarios are set forth above in terms of adjusting the artificial interior lighting such that the lighting in the room is at or near the desired interior CRI, it will be understood that in other embodiments, adjusting the artificial interior lighting can be used to alter the lighting in the room to match CRI and CCT, or a specific default value of CCT. In certain implementations of these techniques for adjusting artificial interior lighting, a user may input settings for adjusting artificial interior lighting. In one embodiment, in the fourth scenario, the user may determine whether to use the interior and/or exterior sensors to control the interior CRI of the room. For example, a user may be a building system administrator who chooses to use external sensors when there are no internal sensors in the room or when internal sensors are not operational. In another embodiment, the user provides the CRI and/or CCT settings used in the room. A user can, for example, place a mobile device, a wall mount (such as, for example, picture twenty three) or other suitable computing device in communication with one or more controllers executing the control logic via a communication network. In some cases, the user may enter schedules with different preferred CRI and/or CCT settings to use at different times of day and days of the year. In other cases, a user may enter an override setting. In another embodiment, the user can select which type or combination of sensor inputs to use to determine the interior CRI of a room. For example, according to the third scenario, the user may choose to use weather forecast data obtained from a specific combination of external sensors to determine internal CRI. In some cases, these external sensors may be located at a separate building and the weather forecast data transmitted to a controller at the building with the room via the communications network. In some embodiments, the control software automatically takes ambient weather conditions as input into account to adjust the internal CRI and whether external and/or internal sensors are used. In one embodiment, the control logic is learned from historical data entered by the user. For example, instances of CRI/CCT settings entered by one or more users in the room and the associated time of that entry (day of year and time of day) may be stored in memory as historical data. Appropriate CRI/CCT settings can be made when evaluating trends in historical data to predict future times. For example, an occupant of a room may select a specific CRI setting every day at the same time every weekday. The control logic stores this information as historical data, evaluates this historical data as a trend, and sets the desired internal CRI level to this setting at (or just before) that same time during the weekdays of the following week. In this way, the control logic can automatically adjust its CRI/CCT settings to suit user preferences. According to certain embodiments, the control logic for the above situations is incorporated into predictive logic that determines the tinting state of one or more electrochromic windows and/or adjusts the interior lighting to obtain the desired color at a future time. Internal CRIs. In the above subsections is set forth a description of the Intelligence® available from View, Inc. of Milpitas, California that can be used to calculate the tint state of one or more electrochromic windows to take occupant comfort and/or energy considerations into account. Instances of Logical Modules Module A, Module B, and Module C. Another example of other predictive control logic for determining the tint state of an electrochromic window is set forth in U.S. Patent Application 15/347,677, filed May 7, 2015, and entitled "CONTROL METHOD FOR TINTABLE WINDOWS," which The application is hereby incorporated by reference in its entirety. picture twenty twoIt is a flowchart of a method according to one embodiment 2200, the method implements predictive control logic for controlling the interior CRI of a room having one or more electrochromic windows. Although this method is described with respect to electrochromic windows, the method can be practiced with other tintable windows. in operation 2220, the control logic uses one or more of modules A, B, and C to calculate the tinting level of one or more electrochromic windows in the room at a future time. In one case, the future time used in the calculation may be a time far enough in the future to allow the window to complete the transition after receiving the control signal with the shading instruction. Details about modules A, B, and C are set forth in the above subsections. Modules A, B, and C output tint levels, sensor readings (interior and/or exterior), window configuration including orientation, time of day, time of year for one or more electrochromic windows at a future time the day of the day, the weather conditions that may exist, and other data used by these modules. in operation 2230, the predictive control logic determines the desired/appropriate internal CRI at a future time. In some embodiments, the desired internal CRI is preset as a user preference. In one example, the desired interior CRI may be based on trends in historical data of user input for controlling artificial interior lighting in a room. As another example, the desired internal CRI may be an override value entered by the user. Additionally or alternatively, the desired internal CRI may be based on scheduling information. In some cases, this schedule can be determined or adjusted by the user. In other cases, the control logic may adjust the schedule based on historical data. in operation 2250, the control logic determines adjustments to the interior lighting and/or the tint state of the electrochromic windows to obtain the desired/proper interior CRI in the room. For example, the control logic may determine the type of light to activate, one or more colors or lights to activate, the intensity level settings for the lights to activate, the location of the lights to activate, the number and arrangement of lights to activate, etc. . Once an adjustment is determined, the control logic sends control signals for adjusting the tinting state of the artificial interior lighting and/or electrochromic windows in the room (operating 2260). method then returns to the operation 2220. In an implementation according to the first scenario, the interior CRI of a room is determined based on the tinting state of one or more electrochromic windows. In one example, when the tint status from modules A, B, and C is at a certain level, and the interior lighting is on in a room occupied by the user, the control logic automatically determines the adjustment and sends a control signal to automatically adjust the interior lighting. Lamp to provide user-preset internal CRI. According to an implementation of the second scenario, measurements from one or more interior sensors in the room are used to determine the interior CRI value of the room. In one example, the control logic automatically determines adjustments to interior lighting and/or tinting levels that adjust the CRI value to the desired level. According to an implementation of the third scenario, measurements from one or more external sensors may be used to determine the external CRI converted to internal CRI based on the tinting level of one or more electrochromic windows. For example, assuming that the curtain walls of windows are all in the same tinting state, one internal CRI can be obtained, but if one or more windows in the curtain wall of windows are tinted to different tinting states, a different internal CRI value is obtained and can be obtained by This different interior CRI value is adjusted by changing the interior lighting accordingly. In one embodiment, the inner CRI is only adjusted based on a calculated value based on the tinting state of the window and the measured outer CRI. According to an implementation of the fourth scenario, measurements from one or more external sensors and/or internal sensors may be used to determine the internal CRI as described above with respect to the first and second scenarios And determine the adjustment. In certain embodiments, based on the four scenarios, the predictive control logic with modules A, B, and C also includes an override logic module. In this embodiment, the override logic module may adjust (override) the tint state of one or more electrochromic windows determined by modules A, B, and C and/or adjust the interior lighting to achieve Required CRI. For example, when implementing the third case, the control logic can determine whether to use the tinting state output from modules A, B, and C, the curtain wall of the window will be in the darkest tinting state at a future time. In such a case, in order to obtain a proper CRI, the interior lighting will need to be adjusted to a high intensity setting at a future time. The control logic can also determine that proper CRI can be obtained without interior lighting turned on if a subset of windows remains in a lower tinted state. In this example, the control logic may decide to adjust a subset of the windows to a lower tinted state at a future time and not adjust the interior lighting. e. Dynamic awareness of occupancy input and occupant position In certain implementations, control logic is used to control the tinting state of each tinting zone of a multi-zone tintable window, individual windows in a group (or zone) of windows, or a combination thereof. In some cases, the control logic first determines whether the room with the window is occupied or unoccupied. Control logic may be based on one or more data, such as, for example, scheduling information, occupancy sensor data, asset tracking information or other occupant tracking data, via a remote control or such as picture twenty threeThe wall units shown in are derived from one or more of the user's activation data, etc., to make their determinations. The remote control may be in the form of a handheld device such as a smartphone or may be a computing device such as a laptop. For example, control logic may determine that a room is occupied if the scheduling information indicates that an occupant is likely to be in the room. As another example, control logic may determine that a room is occupied based on readings from occupancy sensors. In another example, the control logic may determine that a room is occupied if an occupant has entered information indicating occupancy at the manual control panel of the wall unit or remote control. If the room is occupied, the control logic determines whether a glare condition exists in the occupied or potentially occupied area. The control logic determines the tinting status of the tinting zone based on the occupant's location in the room. For example, the state of shading can be determined to avoid glare on a table or other area that may be presumably occupied or occupied. In some cases, the occupant's current location is based on information retrieved from an occupancy lookup table. In other cases, the occupant's current location is based on data in signals from sensors (eg, occupancy sensors). The sensors can generate a signal with the occupant's location in the room. The window controller can receive this signal. As another example, a user may provide information about an occupant's location in a room, such as via a control panel in the room. picture twenty threeis a photograph of an example of a wall unit with a manual control panel according to an embodiment. In some aspects, a method of control determines the tinting status of a tinting zone in a multi-zone tintable window having a daylighting tinting zone. In such cases, the control method determines the state of shading to maximize daylighting while controlling glare and/or heat load from solar radiation entering the room. In some aspects, the user may use a control panel (e.g., a manual control panel in a room or a computer interface) to select a "lighting mode" or "uniform mode," another predetermined mode, or a user-defined one. model. For example, a user may be able to customize different tinting states for regions of windows in a room, eg, "User 1 - Mode 1". In the "lighting mode", the control method determines the transparent coloring state or the coloring state that is brighter than other coloring areas for the lighting coloring area of the window. In Uniform Mode, the control method judges the shading state of an area based on a different standard than that used for daylighting. e. Multi-zone preference / Feedback notification of occupancy mode In some aspects, the control logic used to control the tinting state of tinting areas/windows is informed based on feedback of preferences and occupancy patterns. For example, the location of occupants at different times/dates, as determined by sensors, from user input, etc., can be stored as occupancy patterns. These occupancy locations at different times/dates can be used to predict the occupant's location at a future time. The control method may then control the shaded state based on the predicted occupant locations. As another example, user input selecting certain shaded states at certain times for different shaded regions may be stored. Such tinting choices by the user can be used to predict the likely desired tinting state in the room. The control method can then control the shading state according to these predicted shading states desired by the user. F. Projection of light into a room for judging glare conditions In some embodiments, the control logic includes instructions to determine whether direct sunlight passing through the tinted zone creates a glare condition in the occupied area by calculating the three-dimensional projection of light from the tinted zone in the room. The three-dimensional projection of light can be thought of as a volume of light in which external light in the room falls directly into the room. For example, a three-dimensional projection can be defined by parallel rays from the sun passing through the tinted zones of a multi-zone window. The direction of the 3D projection into the room is based on solar azimuth and/or solar altitude, which can be calculated by a solar calculator based on the time of day and the longitude and latitude coordinates of the window. Three-dimensional projections of light can be used to determine intersections with occupied areas in a room. The control logic determines the lightcast at a particular plane and determines the amount by which the lightcast or a glare area associated with the lightcast overlaps the occupied area. If the light projection system is outside the occupied area, it is determined that there is no glare situation. Details of the control logic for determining glare situations using three-dimensional projections of light are set forth in PCT application PCT/US15/29675, filed May 5, 2015, and entitled "CONTROL METHOD FOR TINTABLE WINDOWS," which application is hereby incorporated by reference The method is integrated as a whole. picture 24A, picture 24Band picture 24Cfor each having room (vertical walls not shown) according to one embodiment 2400Schematic diagram of the perspective view of the room with the exterior of the building and the room 2400Multi-zone windows in vertical walls between interiors 2410, the multi-zone window has the first shaded zone 2412and the second colored area 2414. picture 24A, picture 24Band picture 28CThree different situations of sunlight are shown separately, where the sunlight is in three different directions associated with different positions of the sun 2450, 2460, 2470(shown as dotted arrow) shines through the multi-zone window 2410. In the example shown, the room 2400Occupied area having the location or potential location of the occupant 2450. occupied area 2450This could be, for example, a desk or another workplace. In this instance, occupying the area 2450defined as a room 2400A two-dimensional area on the floor. exist picture 24A, picture 24Band picture 28CIn each of the illustrated examples shown in , sunlight (shown as directional arrows) illuminates the multi-zone window 2410the first coloring area 2412and the second colored area 2414. According to one aspect, the control logic decides to pass through the two shaded regions based on the position of the sun 2412, 2414each of and across the room 2400projection of light. Control logic decision goes through two shaded regions 2412, 2414Each of the light and include two-dimensional footprint 24502D light projection at the intersection of the plane of the room 2400The surface of the floor is coplanar. exist picture 24A, showing passing through the first shaded region 2412first two-dimensional light projection 2416, and draw across the room 2400Second colored area on the floor 2414The second two-dimensional light projection of 2418. exist picture 24B, showing passing through the first shaded region 2412first two-dimensional light projection 2416, and draw across the room 2400Second colored area on the floor 2414The second two-dimensional light projection of 2420. exist picture 24C, showing passing through the first shaded region 2412first two-dimensional light projection 2426, and draw across the room 2400Second colored area on the floor 2414The second two-dimensional light projection of 2428. The control logic then determines whether the two-dimensional lightcast from the shaded region intersects the occupied area. If the two-dimensional lightcast intersects the occupied area, the control logic places (remains in or transitions to) the corresponding shaded region in a darkened shaded state. Although two colored regions are shown, it will be understood that additional regions and/or differently positioned colored regions would be suitable using a similar approach. exist picture 24AIn the first case shown in , for example, passing through the colored area 2412, 2414two-dimensional light projection 2416, 2416Neither occupied area 2450intersect. In this case, the shaded area 2412, 2414Put in a clear state. exist picture 24BIn the second case shown in , the first 2D light projection 2420and occupied area 2450intersects, and the second 2D ray casts 2422does not occupy the area 2450intersect. In this case, the first shaded area 2412Put in a darkened shading state to avoid glare situations. Due to the second two-dimensional light projection 2422unoccupied area 2450intersects, so the second shaded region 2414Put in a clear state. exist picture 24CIn the third case shown in , the first 2D light projection 2426and second two-dimensional light projection 2428and occupied area 2450intersect. In this case, the first shaded area 2412and the second colored area 2414Place a darkened shading state to fill in occupied areas 2450Avoid glare situations. Although picture 24A ,picture 24Band picture 24CThe example shown in includes a multi-zone tintable window, but similar techniques would apply to separate and adjacent tintable windows. For example, a room may have two separate and adjacent tintable windows in the vertical wall between the exterior of the building and the interior of the room. Using control logic, three-dimensional projections of light from each tintable window are directed through the room based on the position of the sun. The control logic determines the two-dimensional lightcast through each window at the plane of the occupied area. The control logic then determines whether the two-dimensional lightcasts from each window intersect the occupied area. If the two-dimensional lightcast intersects the occupied area, the control logic places (remains in or transitions to) the corresponding window in a dimmed tinted state. G. Used to control glare, ambient light level and color and / or control logic for ratio Certain embodiments relate to control logic that adjusts artificial lighting and/or tinting of tintable windows to provide relatively constant brightness levels and ambient spectral content in an occupied area. Typically, the control logic adjusts the artificial lighting and/or the tinting of the tintable windows so that the combined light illuminating the surfaces of objects in the occupied area resembles the natural spectrum so that illuminated objects reflect their true colors. While typically set to a natural spectrum, the ambient spectrum content can alternatively be customized for the current occupant to provide, for example, soothing light, light therapy to adjust circadian rhythms, or provide restorative healing, etc. By adjusting the tinting state of the tintable window, the control logic can control the direct sunlight (glare) passing through the tintable window and the color imparted by light projection through the window (eg, blue light). By adjusting the artificial lighting, the control logic can offset the effects of glare and adjust the color of the environment. Combined control of the shading state and artificial lighting can provide relatively constant ambient light levels and spectral content at desired levels in an occupied area. In one aspect, the control logic can control the adjustable artificial lighting to adjust the color (wavelength range), illumination level, and/or direction of illumination of the illumination. Such adjustments may be selected to increase occupant comfort by reducing glare and improving ambient spectral content and/or reducing contrast ratios in occupied areas. For example, the control logic may control the wavelength and lumen/illuminance settings of the adjustable artificial lighting to shift the contrast ratio in the occupied area. An example of tunable indoor artificial lighting is the BLT series of tunable white LEDs sold by Lithonia Lighting ® which are tunable to different illumination levels varying between 0 and 1000 lux (100%) and between 2700 Kelvin and 6500 Kelvin Adjust the color between. Additionally or alternatively, the adjustable artificial lighting may have multiple light sources in different positions and/or have light sources that are movable to change the direction of light. Control logic can control various light sources of artificial lighting to illuminate certain areas. For example, indoor artificial lighting can be adjusted to direct light to occupied areas with occupants affected by external glare through tinted windows. Reflected light is a combination of light reflected from artificial light and light cast to produce a more uniform intensity and color in an occupied area. This reduces occupant perceived glare, which increases occupant comfort and productivity. As used herein, "negative setting" refers to the setting of an adjustable artificial light source that provides illumination in a wavelength range that is shifted from the color of light passing through a tinted window. For example, if a tintable window in its darkest state imparts a blue color to light passing through the window, the offset color for a negative setting would be red light or a combination of red and yellow light. In this example, an adjustable artificial light source in the negative setting would provide red or red and yellow illumination. In one aspect, the control logic activates a negative setting for the adjustable indoor artificial lighting to direct light to an occupied area with a light cast through a tinted window to offset the effects of glare and color from the light cast. Reducing strong contrast at the interface between portions of a surface illuminated by different illumination sources of different intensities can improve occupant visual comfort. In certain implementations, the control logic adjusts the functionality of the building system based on the current contrast ratio in the area determined based on feedback from the building system. For example, the contrast ratio in an area (such as an occupied area or other surrounding area) may be determined based on the current illumination and/or color of light in the area. Current illumination and color can be determined from one or more of: measurements from one or more sensors in the building (e.g., cameras, thermal sensors, etc.), the current setting and location of artificial lighting wait. An example of a device with sensors that can measure the illuminance and color of ambient light is a spectrometer, such as, for example, the commercially available C-7000 spectromaster manufactured by Sekonic®. The control logic adjusts the functionality of the building systems to adjust the contrast ratio in the area to an acceptable level. For example, the building systems may be adjusted such that the contrast ratio is below an acceptable range or below a maximum limit. As another example, the building systems can be tuned so that contrast ratios are maintained within acceptable levels based on look-up tables of illuminance and color for artificial lighting that can be used to offset The reflected light of the light projection of the electrochromic window. picture 25is a plot of measured illuminance (lux) versus measured color temperature (Kelvin) according to one embodiment. The figure shows three distinct regions: an upper region described as warm and colorful, looking red, a middle region described as pleasing, and a lower region described as cool and dark, appearing blue. This image includes four distances taken at 12:30 pm from the window in its darkest tint state with the artificial lighting turned on at full brightness level and set to 2700 Kelvin The four points of the measured values of illuminance and color temperature. If the artificial lighting is off, the illuminance and color temperature will likely be in the lower area. As shown, the measurement results when the artificial lighting is on shifts the blue light, bringing the measured illuminance and color temperature into the middle and upper regions. Examples of look-up tables include interior artificial light settings (color temperature in Kelvin and brightness level in lux) that will be displayed at specific times of day in occupied areas at different distances from tinted windows While maintaining the contrast ratio within an acceptable level for different coloring states. In one aspect, control logic may use such a lookup table to determine the setting of the internal artificial light that will maintain the contrast ratio within acceptable levels. In certain embodiments, the control logic makes adjustments to artificial lighting settings and tint status of tintable windows based on feedback received from building systems to provide occupant-specific or more generally work-friendly windows in occupied areas. Brightness levels and ambient spectral content for site design. The feedback may include, for example, the current tinting status of tintable windows, information about the presence or likely presence of occupants in an occupied area or workplace, measured levels of illuminance and color of ambient light, information about occupants Data (such as age, gender and circadian rhythm), information about occupied areas or workplaces, etc. This feedback information can come from readings or decisions about data obtained by building systems or can come from scheduling information based on historical data. Control logic can adjust artificial lighting and tinting to produce specific spectral content and brightness levels tailored to occupants or the usage environment (eg, residential, general, commercial) of the workplace. More details about this control logic will be described in the next subsection. In one aspect, you can use and refer to picture twenty twoThe method described is similar to the method to implement the logic for controlling the contrast ratio in the occupied area of a room with one or more tintable windows. In this method, the control logic uses one or more of modules A, B, and C to calculate the tinting level of one or more tintable windows in the room at a future time. In one case, the future time used in the calculation may be a time far enough in the future to allow the window to complete the transition after receiving the control signal with the shading instruction. Modules A, B, and C output tint level, sensor readings (interior and/or exterior), window configuration including orientation, time of day, day of year for one or more tintable windows at a time in the future , weather conditions as the case may exist and other data used by these modules. The predictive control logic determines the acceptable contrast ratio at a future time. The control logic then determines adjustments to the interior lighting and/or the tint state of the tintable windows to obtain a contrast ratio in the room that is below or at an acceptable level. For example, the control logic may determine the type of light to activate, one or more colors or lights to activate, the intensity level settings for the lights to activate, the location of the lights to activate, the number and arrangement of lights to activate, etc. . Once an adjustment is determined, the control logic sends control signals for adjusting the tinting state of the artificial interior lighting and/or electrochromic windows in the room, and then the method returns to modules A, B, and C again. H. Control logic for scenarios designed by occupants Certain embodiments relate to control logic for maintaining scenarios of environmental factors designed to provide occupant satisfaction and comfort levels in a workplace, such as visual comfort, thermal comfort, acoustic comfort, and air quality. The control logic maintains the environmental factors by making adjustments to the settings of the building systems. The control logic designs environmental factors based on various feedback received from, for example, building systems, occupants, building management systems, and the like. Some examples of feedback that may be used include the current state of tinting of tintable windows, data about the presence or likely presence of occupants, measured levels of illuminance and color of ambient light, data about occupants such as age, gender, etc. and circadian rhythm), noise data, ambient temperature data, air quality data, data on available building systems, etc. From the feedback, the control logic determines occupancy, which includes the presence and location of one or more occupants in the workplace. The control logic determines occupancy based on various information, such as scheduling information, sensor measurements, input from occupants, or data from a mapping system. Examples of such mapping systems include transmitters and receivers for transmitting radio frequency, microwave or other electromagnetic waves. Received transmissions can be used to map the current location of occupants and other objects in the workplace. The control logic is also developed for each occupant and/or workplace use case to determine parameters for determining the scene, such as occupant type, workplace type, temporal composition of the surrounding environment (illumination level, ambient light color, noise level, air quality, etc.), dwell duration, building considerations (such as energy and cost), and existing building systems that can be used to alter the surrounding environment. Based on the use case, the control logic designs a scenario that includes all environmental factors, or some portion of the environmental factors, depending on which technologies or controls are in effect at the workplace. Environmental factors may be grouped into categories such as, for example, thermal settings, visual settings, acoustic settings, and air quality settings. The duration of dwell in the workplace is a consideration of some environmental factors such as noise and air quality. For each occupant and/or workplace, control logic determines the environmental factors to be used in the scenario and determines target levels for the environmental factors. Design the classes to meet occupant needs or expectations by determining which classes are designed for that use case. The control logic then determines any new control settings for the building system and communicates those new settings to the building system, eg, via the BMC or BAC. In one aspect, data from industry best practices are used to initialize use case-specific scenarios and then modify the scenarios based on feedback from occupants, building management systems, and/or the industry. Control logic modifies or updates the scenarios based on new environmental factors. For example, the control logic may receive feedback from buildings with unanticipated settings that provide non-intuitive "pleasures" that better match or exceed occupant expectations for workplace settings. In another aspect, the control logic may initialize the scenario for a particular use case based on input from the current occupant, such as based on a series of queries to the occupant at a user interface. In one aspect, scenarios for a particular use case are modified based on feedback from occupants, building systems, building management systems, industry, and any other suitable source of feedback. For example, the control logic may receive overrides or positive or negative feedback from occupants regarding environmental factors of a particular scene. The control logic may determine a new level of the environmental factor of the scene based on the feedback. Some examples of workplace types include private offices, sanctuaries, nooks, contemplative rooms, thinking rooms, huddle rooms, open offices, loud areas, waiting areas, transition areas, meeting rooms, creative thinking spaces, foyers, plazas, restaurants and office space. picture 26is a schematic diagram of a building showing various types of workplaces according to one embodiment. In the example shown, workplaces are grouped into "workplaces for personal work" including workstations and low tables, "workplaces for open collaboration" including individual couches, conference tables, and small meeting rooms, including editing rooms, chat rooms , thinking rooms, meeting rooms, meeting rooms, and meeting rooms; Regional Workplace". The control logic determines use cases based in part on the type of workplace. For example, private offices are often used for focused tasks or creative activities. As a result, private offices require scenes with ambient settings of warm temperatures and warm ambient light. In addition to designing scenes for maximum efficiency, scenes can also be designed to match occupants' expectations of a well-thought-out workplace. For example, a restaurant needs a scene with light levels (illuminance) and background noise that are vibrant and encourage communication and socializing. In this example, the occupant's expectation of the scene in the restaurant would be brighter, noisier and cooler.

Similar to a private office, a thinking room or small meeting room is also an area for concentrating work or taking a break without distraction. Thinking rooms or small meeting rooms are designed to have less privacy for occupants than private offices. Thinking rooms or small meeting rooms can also be enclosed, semi-sheltered or sheltered spaces in an open plan. An example of environmental factors for a scene designed for visual comfort in a thinking room or small conference room includes a brightness level of 1000-2000 lux (high) and a color temperature of 6000K (cool).

An example of an environmental factor for a scenario designed for thermal comfort in a conference room is a brightness level of 20°C to 23°C (moderate). An example of environmental factors for a scenario designed for acoustic comfort in a conference room includes a sound level of 44 dB to 55 dB and a privacy index of 80% to 95%. An example of environmental factors for scenarios designed for air quality control in conference rooms includes 1000 ppm of CO ₂content. A public office, foyer, or social area generally refers to a dynamic, social environment in a building's primary gathering place, where mixing and connection takes precedence over privacy or work output.

The control logic can be executed by one or more controllers. A workplace may be a room in a building or an area within a room. in operation 2710wherein the control logic receives input from occupants, assets within the building, or building systems such as, for example, a window controller for controlling the tinting status of one or more tintable windows in a workplace, an HVAC system, a user Feedback in controlling artificial lighting (interior and/or exterior), lighting systems, security systems, one or more sensors, mapping systems, noise and sound control systems, etc.). For example, feedback can be received from an asset that the occupant is carrying with them, such as a smart phone or other smart device. As another example, an occupant can control a panel via a smart device, a manual control panel (e.g., picture twenty threedevice shown in ) or other devices to feed back into the control logic. Some examples of feedback that may be used by the control logic include the current tinting status of one or more tintable windows in the workplace, data regarding the presence or likely presence of one or more occupants in the workplace, ambient light illuminance and color measurements or other sensor readings, occupant data, ambient temperature data, air quality data, noise or other acoustic data, information about available building systems, etc. In one aspect, the predictive control logic of one or more modules (such as reference picture twenty twodescribed) to determine the tinting state of the one or more tintable windows. Some examples of occupant data include age, gender, occupation, circadian rhythm, activity, vital signs, and the like. In one aspect, the control logic uses the vital signs to determine the occupant's circadian rhythm. refer to picture 16and picture 18Some examples of building systems are described in detail. refer to picture 15, picture 19and picture 20Some examples of window controllers are described in detail. Feedback from building systems is typically received via a communications network. based on operating 2710In response to the received feedback, the control logic decides to occupy ( 2720), including the presence and location of one or more occupants in the workplace. The control logic may determine occupancy based on information such as current time, schedule data, sensor data, input from occupants, data in signals from assets carried by occupants, and data from mapping systems. In one aspect, a mapping system of transmitters and receivers of radio frequency, microwave or other electromagnetic waves in a building may be used to map the current location of occupants and other objects present in the workplace. An example of such a mapping system based on window antennas is set forth in U.S. Patent Application 15/709,339, filed September 19, 2017, and entitled "WINDOW ANTENNAS FOR EMITTING RADIO FREQUENCY SIGNALS," which application is hereby incorporated by reference in its entirety. enter. In another aspect, the control logic may determine that there is a high probability that an occupant is present at the workplace based on scheduling data and the current time. In another aspect, an asset that a particular occupant has with him (eg, a cell phone) has a transmitter that transmits a radio frequency signal that is received at a receiver in the building. Based on the received signals, the building management system or other controller determines the presence and location of the occupants and sends a signal with this information to the controller implementing the control logic. in operation 2730In , the control logic is developed for specific occupant and/or workplace use cases. The use case includes one or more of the following: type of occupancy in the workplace, type of activity in the workplace, type of workplace, temporal composition of the surrounding environment, duration of occupant stay, any building considerations ( types and availability of controls such as energy conservation), building systems, or other technologies that can be used to modify environmental factors. Types of occupancy include information such as age, gender, occupation, circadian rhythm, and vital signs of one or more occupants. The type of activity can be, for example, working, painting, drawing, meeting guests, eating, private thinking, sleeping, resting, hanging out, waiting, gathering, and the like. The temporal composition of the surrounding environment includes various parameters such as illuminance and color of ambient light, contrast ratio, noise, temperature, humidity and air quality. in operation 2740, the control logic determines, for the use case, scenarios of environmental factors designed to improve occupant satisfaction and comfort (eg, visual, thermal, acoustic, and/or air quality) in the workplace. In one aspect, building considerations are taken into consideration in addition to occupant satisfaction and comfort. The control logic determines which environmental factors to include in the scene based at least in part on the types and controls of building systems or other technologies available to alter the surrounding environment. In one aspect, the control logic also considers dwell duration when determining whether to include noise and air quality factors. For example, if the dwell duration is less than 5 minutes, the control logic may not include noise and air quality environmental factors. For each environmental factor in the scene, the control logic determines a target setting or level. Environmental factors are grouped into categories including, for example, thermal settings, visual settings, acoustic settings, and air quality settings. Examples of thermal settings include target levels for temperature, airflow, and humidity. Some examples of visual settings include illuminance and color of ambient light, contrast ratio, and target level of glare. For example, the target level for contrast ratio can be to remain below the maximum acceptable contrast ratio or to be within an acceptable range of values. Acoustic settings include sound or noise levels and a privacy index that factors in walls and open space in a room. The Privacy Index reflects the ability to have conversational confidentiality in the workplace. Some examples of air quality settings include, for example, CO ₂and/or one or more pollutants (such as CO, O ₃, NO ₂, SO ₂, PM ₁₀, PM _2.5and lead) content. Some examples of scenarios for target environmental factors including brightness level (illuminance), color temperature, sound level, privacy index, and air quality are provided above for various types of workplaces. The control logic determines the context of the particular use case's environmental factors by matching all or most of the parameters of the particular use case to the context associated with the context stored in the database. If the database does not have a matching scene, the control logic initializes the environmental factors for the scene. In one example, the control logic uses data from industry best practices to initialize the environmental factors for a particular use case scenario. In another example, the control logic uses data from the occupants to initialize the scene, such as by querying the occupants for a better environment setting. In another example, the control logic initializes the scene using data from occupants with a similar set of parameters in the use case. In one embodiment, after the control logic determines a first scenario of environmental factors for a particular use case, the control logic further modifies the environmental factors to generate a second scenario based on additional feedback from buildings with unanticipated settings , these settings provide non-intuitive "joys" that better match or exceed occupant expectations for workplace settings. will be operating 2740The selected scenes are saved to the database. In one aspect, scenarios for a particular use case are modified based on feedback from occupants, building systems, building management systems, industry, and any other suitable source of feedback. For example, the control logic may receive overrides or positive or negative feedback from occupants regarding environmental levels of a particular scene. The control logic may determine a new level of the environmental factor of the scene based on the feedback. in operation 2750, the control logic determines the control settings for the various building systems that will result in operating 2740Target environmental ratings for scenarios designed for occupants or workplaces. For example, the control logic may use a look-up table to determine the appropriate control settings that will produce the target environmental factor. in operation 2760In, the control logic transmits the control settings to the controllers of various building systems building systems or building management systems or building control systems. The control logic then returns to the operating 2710.
