Abstract

The energy management system capable of increasing consciousness of a user for energy saving and inducing the user to act for the energy saving by means of providing energy-saving information is provided. In the energy management system, a center device SV includes an information database where bits of knowledge are successively stored as energy-saving information. Upon receiving a display request to display a display screen for displaying the bits of knowledge from a terminal device such as a display control device CV, a personal computer PC, and a portable terminal PT, the center device SV generates image data of the display screen for displaying the bits of knowledge and transmits the same to the terminal device that is a requestor of the display screen. The terminal device displays the image data received from the center device SV.

Claims

1. An energy management system comprising:

a home appliance located in a home; and

a terminal device connected to said home appliance,

wherein said home appliance comprises a current measurement unit, an electrical energy calculation unit, and a processing unit,

said current measurement unit being configured to measure a current flowing through each branch breaker connected to an output terminal of a main breaker,

said electrical energy calculation unit being configured to calculate electricity usage at each of said branch breakers on the basis of a measurement of said current measurement unit, and

said processing unit being configured to generate information of electricity usage at the home on the basis of the electric usage calculated by said electrical energy calculation unit,

wherein said terminal device comprises a display unit adapted in the use of displaying the information of the electricity usage generated by said processing unit,

wherein said energy management system comprises a server connected to said home appliance via an outside network, and

wherein said server comprises a storage unit and an information transmission unit,

said storage unit being configured to store energy-saving information including information indicative of a method of energy saving, and

said information transmission unit being configured to transmit the energy-saving information stored in said storage unit to said terminal device.

2. An energy management system as set forth in claim 1,

wherein said information transmission unit is configured to transmit the energy-saving information to said terminal device at a prescribed timing.

3. An energy management system as set forth in claim 1,

wherein said information transmission unit is configured to transmit the energy-saving information to said terminal device in response to a request from said terminal device.
