Abstract

Une base de données d'informations de fonctionnement d'appareil (113) acquiert des informations de fonctionnement, qui consistent en l'état actuel de fonctionnement et en la quantité d'énergie consommée par les appareils (153a à 153c) utilisés par un utilisateur, par l'intermédiaire d'une unité de surveillance (163) prévue dans un système domestique (150). Par rapport à un type de situation dans laquelle au moins certains des appareils actuels sont remplacés par des appareils différents et/ou une situation dans laquelle un autre appareil est ajouté, une unité d'exécution de simulation (105) calcule le degré de charge environnementale au moyen d'une simulation dans laquelle l'état de fonctionnement mémorisé dans la base de données d'informations de fonctionnement d'appareil (113) est appliqué à l'appareil différent ou à l'autre appareil, et présente un plan de réduction pour lequel la simulation a été effectuée à un terminal d'utilisateur (151). La proposition d'un plan de réduction comprenant le remplacement d'un appareil ou l'ajout d'un appareil à un utilisateur tient compte d'une réduction effective du degré de charge environnementale conformément à un objectif fixé par l'utilisateur.
