Patent attributes
A comparison unit compares the outside air temperature in outside air temperature information acquired by an outside air temperature acquisition unit with an outside air temperature threshold that has been set by a threshold setting unit. A first information acquisition unit acquires ON operation information. A device control unit performs passive control when the outside air temperature is in a temperature range on a comfortable side with respect to the outside air temperature threshold. Where the outside air temperature is in a temperature range on an uncomfortable side with respect to the outside air temperature threshold, the device control unit performs passive control until an ON operation is performed and performs active control once the ON operation is performed. The passive control involves performing OFF control of the active device and natural environment usage control of a passive device. The active control involves performing ON control of the active device.
