Energy saving proposed system, energy saving proposed method

摘要

An appliance operation information database (113) acquires operation information, which is the current state of operation and amount of energy expended of appliances (153a to 153c) used by a user, via a monitoring unit (163) provided in an in-home system (150). With respect to a type of situation wherein at least some of the current appliances are replaced with different appliances and/or a situation wherein another appliance is added, a simulation execution unit (105) calculates the degree of environmental load by way of a simulation in which the state of operation stored in the appliance operation information database (113) is applied to the different appliance or the other appliance, and presents a reduction plan for which the simulation has been carried out to a user terminal (151). The proposing of a reduction plan including replacement of an appliance or addition of an appliance to a user allows for effective reduction of the degree of environmental load according to an objective that is set by the user.
