It should be noted that the processing contents and processing procedure shown in FIG. 9 are an example, and the present invention is not limited to this. For example, some processes may be performed concurrently in parallel or may be interchanged.

As described above, in this embodiment, normally, power obtained by collectively receiving low-voltage power from the grid power and power generated by the solar cell module 306 are supplied to the consumers 315 in the common area and the living area. In addition, for example, during the daytime, the power generated by the solar cell module 306 is supplied to each residence and stored in the storage battery 307 . At night, the power stored in the storage battery 307 is supplied to each residence. As described above, in this embodiment, the generated power can be used in the collective housing as much as possible, and the amount of power purchased from the business operator can be reduced.

Therefore, according to the business model of the present embodiment, the purchase of the generated power by the occupants makes it possible to raise the occupants' awareness of contributing to the environment and encourage local production and local consumption of electric power. According to the business model of the embodiment, by using the purchased power at, for example, the office operated by the first business operator 103, the power consumed by the business activities of the first business operator 103 or the second business operator 108 can be reduced. We can contribute to the replacement with renewable energy and contribute to the realization of a wider, carbon-neutral society.

In addition, according to the business model of the embodiment, building owners can compete in acquiring tenants by owning rental housing with high environmental value and high resilience without the cost of installing and maintaining equipment. It can meet the needs of strengthening power and participation in a decarbonized society. Furthermore, according to the business model of the embodiment, tenants can purchase electricity with a high percentage of renewable energy at a lower rate than major electric power companies. In the event of a power outage, the power supplied from the storage battery to the common areas can be used, for example, to charge smartphones, helping to resolve information shortages after a disaster.

In conventional multi-family housing, for example, if a solar cell power generation system is installed for each dwelling, the amount of power used varies from dwelling to dwelling. was not distributed, and it was necessary to purchase the shortfall from electric power companies. In contrast, in embodiments, if there is surplus electricity, it can be allocated to the residences in need.
