A demand control device includes a storing unit (21) arranged to store performance data of a power consumption accumulated value by environmental condition in a power database (24), and a predicted value calculating unit (21) arranged to, at a start of a demand time period, calculate a predicted value of the power consumption accumulated value for the demand time period based on the performance data stored in the power database (24). Each of the environmental conditions is specified by a time zone and an environmental condition other than the time zone. The predicted value calculating unit (21) extracts the performance data that the time zone corresponds to this demand time period and that the environmental condition other than the time zone coincides with the current environmental condition, from the power database (24) and then calculates the predicted value of the power consumption accumulated value for this demand time period based on the performance data thus extracted.
