Abstract

La présente invention concerne un procédé et un appareil pour réduire les coûts énergétiques et la consommation d'énergie d'un bâtiment à l'aide d'une source d'alimentation distribuée à l'intérieur du bâtiment. Le procédé pour réduire les coûts énergétiques et la consommation d'énergie d'un bâtiment à l'aide d'une source d'énergie distribuée à l'intérieur du bâtiment, selon un mode de réalisation de la présente invention, comprend les étapes consistant à : régler une valeur cible de réduction de pic par analyse de données de consommation d'énergie du bâtiment précédentes d'un système de gestion de l'énergie de bâtiment (BEMS) destiné à gérer l'énergie du bâtiment ; mesurer la quantité d'énergie de charge consommée dans le bâtiment ; et comparer la quantité mesurée d'énergie de charge consommée à la valeur cible de réduction de pic réglée, ce qui permet de réduire les coûts énergétiques au moyen de la commande d'au moins un élément parmi une source d'alimentation distribuée, une charge et un système de stockage d'énergie (ESS).
