  • Publication number: 20200208863
    Abstract: According to one embodiment, an air-conditioning control device includes model storage and a processor. The model storage is configured to store a discomfort probability model which estimates a value of discomfort of an occupant by a pair of time elapsed after an energy-saving operation of an air conditioner is turned on and before the energy-saving operation is turned off by the occupant, and an air-conditioning state at the time when the energy-saving operation is turned off. The processor is configured to acquire a current air-conditioning state during the energy-saving operation of the air conditioner, and turn off the energy-saving operation, based on occupant's discomfort estimated from the discomfort probability model.
