<P>PROBLEM TO BE SOLVED: To provide a power supply system for a building capable of efficiently performing power discharge from a power storage part. <P>SOLUTION: A building power supply system having a power storage part which stores power supplied from at least one of a power generation part performing power generation by utilizing natural energy and a commercial power supply, and discharges the stored power in performing power supply to a load in a building comprises: a data acquisition part which measures power consumption of the load and acquires power consumption data showing the power consumption; a data storage part which stores the power consumption data acquired by the data acquisition part; a specification part which specifies a time zone of a day where the magnitude of the power consumption of the load is kept within a predetermined range for equal to or more than predetermined time, as a specified time zone, on the basis of the power consumption data read out from the data storage part; and a switching part which makes the power storage part switch between power storage and power discharge. The switching part starts continuous discharge of the power stored in the power storage part from time of a day corresponding to the beginning of the specified time zone specified by the specification part, and keeps the continuous discharge after the start of the discharge until the discharge of the power stored in the power storage part is completed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
