<p><P>PROBLEM TO BE SOLVED: To level demand electric power while saving energy by using the solar radiation incident from a light receiving section. <P>SOLUTION: A demand control system 45 controls an air-conditioner 1, a lighting system 2 and a solar radiation amount regulating device 3 so as to reduce power consumption in accordance with the schedule having a first priority control period wherein the first control state for increasing the solar radiation amount regulated by the solar radiation amount regulating device 3 while reducing the power consumption by the lighting system 2, is carried out preferentially to the second control state for reducing the power consumption by the air-conditioner 1. On a fine day, for example, if a time zone in the afternoon (a time zone Tx for executing demand control, in particular) is the first priority control period while reducing the solar radiation amount during a time zone in the forenoon, the power consumption by the lighting system 2 during the time zone in the afternoon is reduced to suppress the peak of the demand electric power. Resultantly, the demand electric power is levelled, while saving energy by using the solar radiation incident from the light receiving section. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
