Control apparatus, control method, and non-transitory computer readable medium for occupant-based energy prediction

A control method performed by a computer, the control method comprising:

• acquiring first information indicating a number of people in a target building during a predetermined time period, second information indicating electrical energy consumed in the target building during the predetermined time period, and third information indicating a number of people heading to the target building during the predetermined time period;
• estimating, based on the first information, the second information, and the third information, a demand for electrical energy for the building for a future target time period;
• and
• transmitting the estimated demand for electrical energy for the building for the future target time period to a server to cause the server to control one or more load apparatuses to reduce usage of electrical energy based on the estimated demand for electrical energy for the future target time period to ensure that sufficient electrical energy is available for the building, wherein
• the computer includes a communication interface, and
• the control method further comprises:
• communicating via the communication interface with a vehicle traveling to the building;
• measuring a number of people heading to the building based on vehicle position information indicating a position of the vehicle;
• and
• acquiring the third information according to the number of people heading to the building based on the vehicle position information indicating the position of the vehicle.

A non-transitory computer readable medium storing a program configured to cause a computer to execute operations, the operations comprising:

• acquiring first information indicating a number of people in a target building during a predetermined time period, second information indicating electrical energy consumed in the target building during the predetermined time period, and third information indicating a number of people heading to the target building during the predetermined time period;
• estimating, based on the first information, the second information, and the third information, a demand for electrical energy for the building for a future target time period;
• and
• transmitting the estimated demand for electrical energy for the building for the future target time period to a server to cause the server to control one or more load apparatuses to reduce usage of electrical energy based on the estimated demand for electrical energy for the future target time period to ensure that sufficient electrical energy is available for the building, wherein
• the computer includes a communication interface, and
• the operations further comprise:
• communicating via the communication interface with a vehicle traveling to the building;
• measuring a number of people heading to the building based on vehicle position information indicating a position of the vehicle;
• and
• acquiring the third information according to the number of people heading to the building based on the vehicle position information indicating the position of the vehicle.
