1. A control device for controlling facility equipment comprising:

  • a receiving unit including a network interface, the receiving unit being configured to receive time-of-use unit price information of an energy to be supplied to the facility equipment during a predetermined period;

    a controller including a processor and a memory, the controller being programmed to includea first decision unit programmed to decide a first time slot in which an index that includes a factor of an energy unit price approaches a peak in the predetermined period based on the time-of-use unit price information;

    a second decision unit programmed to decide a second time slot prior to the first time slot and a third time slot subsequent to the first time slot in the predetermined period; and

    an adjustment control unit programmed to execute an energy adjustment control to adjust an energy consumption of the facility equipment so thatan amount of suppression of the energy consumption in the third time slot is equal to or lower than an amount of the suppression of the energy consumption in the first time slot, andan amount of the suppression of the energy consumption in the second time slot is lower than the amount of the suppression of the energy consumption in the third time slot,the first decision unit being further configured to delay a starting time of the first time slot by a predetermined interval when the first time slot as decided would start at a starting time of the predetermined period, thereby lowering the amount of the suppression of the energy consumption at the starting time of the predetermined period.
