Les procédés peuvent être mis en œuvre par un ou plusieurs processeurs, et les étapes peuvent consister : à extraire des données de consommation d'énergie et une pluralité d'attributs d'une maison à compteur non intelligente, à extraire des données de consommation d'énergie, des données de consommation d'énergie de niveau d'appareil, et une pluralité d'attributs d'un ensemble prédéfini de maisons à compteur intelligentes, à mettre en correspondance les données de consommation d'énergie et les attributs de la maison à compteur non intelligente avec l'ensemble prédéfini afin d'identifier un ensemble de maisons homologues ; à estimer la désagrégation de l'appareil de la maison à compteur non intelligente sur la base des données extraites des maisons homologues identifiées, et à prévoir et à projeter une facture d'électricité et/ou une consommation de cycle moyen et/ou une consommation de fin de cycle et/ou une désagrégation de maisons non intelligentes et/ou une combinaison correspondante.
