  • Patent number: 9964930
    Abstract: The control device controls facility equipment and includes a receiving unit, first and second decision units and an adjustment control unit. The receiving unit receives time-of-use unit price information of an energy supplied to the facility equipment. The first decision unit decides a first time slot in which an index that includes a factor of an energy unit price approaches a peak in a first period based on the time-of-use unit price information. The second decision unit decides a second time slot prior to the first time slot and a third time slot subsequent to the first time slot in the first period. The adjustment control unit executes an energy adjustment control to adjust an energy consumption of the facility equipment so that an amount of suppression of the energy consumption is higher in the first time slot than in the second and the third time slots.

  • Patent number: 9459644
    Abstract: An energy control device adjusts an amount of energy of a plurality of pieces of equipment placed at a property. The energy control device includes a receiving unit, a basic adjustable amount calculation unit, and a control instruction generation unit. The receiving unit receives an energy suppression request including information related to a requested suppressed amount of energy at the property. The calculation unit calculates, upon receipt of the energy suppression request, a basic adjustable amount of energy for each piece of equipment independently of the requested suppressed amount based on an operating status of the piece of equipment when the energy suppression request is received. The generation unit instructs the equipment to perform energy amount adjustment control so that a total of suppressed amounts of energy at the property becomes equal to the requested suppressed amount based on the basic adjustable amount of energy for each piece of equipment.
