Energy management system, energy management method, and unit for providing information on energy-saving recommended equipment

摘要

An energy management system is provided which is capable of calculating, based on equipment information on electrical equipment which is used by a resident, a power consumption estimated when a replacement is made with energy-saving equipment, then comparing and displaying it and the power consumption of the electrical equipment owned by the resident, and thereby, allowing the resident to become aware of how the replacement helps save energy. This energy management system includes: an equipment adapter 110 which is provided in electrical equipment such as an air conditioner, a lighting apparatus and a refrigerator, and obtains equipment information such as a power consumption and an operating state; a data center 170 which obtains equipment information on the equipment adapter 110; an energy-saving equipment database 190 which provides energy-saving equipment data to the data center 170; and a display unit 130 which displays energy-saving recommended-equipment information created based on the equipment information and the energy-saving equipment data by the data center 170.
