The outside air that has entered the storage room 36 through the outside air introduction means 8 and the pipe 37 absorbs the heat and moisture in the storage room 36 and is discharged from the exhaust port 10, and the air in the storage room 36 is naturally ventilated.

The louver 5 and the outside air introducing means 8 can be arbitrarily opened and closed. For example, when the temperature of the outside air is low in winter or the like, only the louver 5 can be intentionally made open, and when it is desired to completely shut off the outside air and the house due to a storm or the like, the louver 5 is used. 5 can be closed to prevent outside air from entering.

According to the embodiment of the present invention, the cool outside air entering from the louvers 5 on the first and second floors not only circulates along the outside of the inner wall 2 but also circulates in the living space 9. The heat and moisture accumulated in the space 9 are released to the gap 3, and the warmed air rises to the tower 7 on the roof.
Is discharged to the outdoors.

[0026]

According to the present invention, since the first air passage and the second air passage are formed, heat and moisture can be effectively discharged from both the inside and the outside of the inner wall. Even if you do not use a cooler or ventilation fan while you are away, hot air is not trapped in the living space and the gap between the outer wall and the inner wall when you return home in the evening, and the temperature and humidity are about the same as outside air. It can be kept, and there is no mold and mite in the house and no condensation. Furthermore, by using an outside air introduction device that can mix the outside air and the air in the living space by operating an adjusting plate that can adjust the opening degree as the outside air introducing means, the temperature of the outside air and the air in the living space can be increased. An air-fuel mixture having a reduced difference in humidity and humidity can be introduced into the living space. Therefore, the climate of residential building
Even if the temperature difference and humidity difference between the inside and outside of the inner wall change variously due to changes in weather conditions and conditions in the living space,
The effect of preventing dew condensation in the living space is further ensured.

Moreover, the effects of the present invention as described above can be obtained by utilizing a natural air circulation cycle.
There is also an advantage that no electricity bill is required.
