It is mainly comprised from the ceiling part 1e which block | closes the upper end opening of the part 1d.

  The space surrounded by the ceiling portion 1e and the outer wall portion 1d is configured such that the under floor space 3 and the indoor space 6 such as a living room are separated by a floor portion 1a as a floor.

  Further, a heat insulating material 2 such as glass wool is attached to the side of the underfloor space 3 of the side wall concrete 1c, so that heat in the underfloor space 3 is prevented from leaking to the outside as much as possible.

  And in this Example 1, the storage battery 4 which incorporated the charger (not shown) in the underfloor space 3 is installed.

  Moreover, the solar cell panel 5 as a private power generation means by natural energy is provided in the upper part of the ceiling part 1e.

  In addition, as a private power generation means by natural energy, it is not limited to the solar cell panel 5, For example, you may implement using a wind power generator etc.

  Further, as shown in FIG. 2, the building 1 includes a distribution board 7, a general power 8 of an external system, a solar panel 5, a storage battery 4, a first power conditioner 11, a second power conditioner 12, and a control. A power supply system mainly composed of the device 13 is provided.

  Here, the distribution board 7 is connected to the general power 8 of the external system via the watt-hour meter 9.

  The distribution board 7 is connected to household electrical appliances 10 such as lighting and television.

  Furthermore, the solar panel 5 is connected to the distribution board 7 via the first power conditioner 11.

  In addition, the storage battery 4 is connected to the distribution board 7 via a second power conditioner 12.

  Furthermore, the solar cell panel 5 and the storage battery 4 are connected via the first power conditioner 11.

  Further, a control device 13 is connected and provided between the general power 8 of the external system, the storage battery 4, the first power conditioner 11 and the second power conditioner 12.

  The control device 13 monitors the general electric power 8, the storage battery 4, the power conditioner 11, and the power conditioner 12 of the external system, and plays a central role in the power supply system that performs control so as to properly operate them.

  Specifically, as shown in FIG. 3, when the external system general power 8 is normally supplied, the storage battery 4 stores the external system general power 8 at midnight when the charge is low.

  Here, the household electrical appliance 10 such as a refrigerator is also operated by the general electric power 8 of the external system at midnight when the charge is low.

  In addition, when the solar panel 5 and the storage battery 4 alone can provide power consumption in the building 1 (electric power consumed by the household electrical appliance 10) during the daytime, as shown in FIG. Power can be transmitted to an external system and sold.

  With such a configuration, the life of the storage battery 4 can be extended as compared with the prior art, and the possibility of functioning in the event of an emergency can be improved.

  Here, in the Kitakinki region, a model house of the building 1 of Example 1 is constructed, and the temperature A of the underfloor space 3 and the indoor space 6 of the indoor space 6 are changed from March 20 to April 9 where the temperature changes drastically. The temperature B, the outside air temperature C, and the temperature D of the upper surface of the foundation bottom concrete 1b in the underfloor space 3 were measured.

  As a result, as shown in FIGS. 9 to 11, the outside air temperature C greatly changed with a maximum width of about 22 ° C., and the temperature B of the indoor space 6 also changed with a width of about 7 ° C. The temperature A of the space 3 is always 13 ° C. to 14 ° C., and it has been proved that the temperature A is suitable for extending the life of the stable storage battery 4 that changes only in the range of about 1 ° C.

  In addition, since the storage battery 4 does not occupy the indoor space 6, the degree of freedom in designing the building 1 can be increased.

  Further, the building 1 is provided with a solar cell panel 5 as a self-power generation means using natural energy.

  When the external system general power 8 is normally supplied, the storage battery 4 stores the external system general power 8 at midnight, and the solar panel 5 and the storage battery 4 alone consume the power consumption in the building 1. When it is possible, the surplus power can be transmitted to the external system and sold, and when the power from the solar panel 5 and the storage battery 4 alone cannot cover the power consumption in the building 1, the shortage power is supplied to the external system. The storage battery 4 is provided with a power supply system that stores electricity by the surplus power from the solar battery panel 5 when the general power 8 of the external system is not normally supplied.

  For this reason, when the general power 8 of the external system is normally supplied, it contributes to energy saving and can lead a normal life economically. Even when the general power 8 of the external system is not normally supplied, You can live a normal life.
