Abstract

L'invention concerne un dispositif de commande (2) qui prédit de manière régulière la tendance de consommation d'énergie dans une maison (H). Sur la base de la tendance de consommation d'énergie prédite et du coût de l'électricité par unité de temps spécifique (ou de la dépense d'énergie par période de temps spécifique), le dispositif de commande (2) spécifie une période de temps pendant laquelle la réduction de la consommation d'énergie a un effet maximal sur la réduction des coûts énergétiques. Le dispositif de commande (2) configure la période de temps spécifiée comme étant une période de temps spécifique. Pendant la période de temps spécifique configurée, le dispositif de commande (2) commande plusieurs appareils (5) installés dans la maison (H) sur la base d'un niveau de réduction défini à l'avance par l'utilisateur.
