The lower part opens to the outside air near the floor of the building, and the upper part opens to the attic 10 near the eaves. Therefore, the eave ventilation opening 18 provided near the eaves of the attic 10 has the attic volume, roof shape,
The number, size and the like of the outer wall ventilation holes 20 are determined in consideration of the shape and the like.

The number, shape, size, etc. of the ventilation openings 3, 9, 11 can be determined in consideration of the volume of the room, the shape of the room, the external environment and the like. In addition, ventilation openings 3, 9, 11
4, a ventilation port opening / closing device 21 that can be opened / closed can be provided as shown in FIG. The opening / closing blades 22 of the ventilation opening / closing device 21 can be configured to open / close in conjunction with a temperature / humidity sensor 23 provided nearby by using the solar cell 16 as a power source. The opening / closing mechanism of the opening / closing blades 22 can be controlled to be either fully open or fully closed in the case of a relay type that utilizes the action of a magnet, and the opening / closing angle can be set to a small degree when a motor driven type such as a stepping motor is used. Can be adjusted.

In the embodiment having the above structure, the working mode of the building ventilation system according to the present invention is as shown in FIG. 5, for the indoor ventilation of the living room 1 on the first floor, the ceiling ventilation port 3 and the air space. Via the attic ventilation fan 15 and / or natural ventilation to the outside of the attic ventilation opening 12 and / or eaves ventilation opening 18 and vice versa. Air is taken in from 18 and the indoor ventilation of the living room 1 on the first floor is performed through the ceiling ventilation port 3 and the air space 7. The indoor ventilation of the living rooms 4 and 5 on the second floor is discharged from the ceiling ventilation port 11 to the attic ventilation fan 15 and / or to the outside of the attic ventilation port 12 and / or the eave ventilation port 18 by natural ventilation. On the contrary, the air is taken in from the eave ventilation port 18 by natural ventilation, and indoor ventilation is performed. Further, ventilation of the attic 10 is performed through the attic ventilation fan 15 and / or the attic ventilation opening 12 and / or the eave ventilation 18 by natural ventilation. Inside the wall of the outer wall, through the outer wall ventilation hole 20,
The attic ventilation fan 15 and / or natural ventilation is used to discharge the air from the attic ventilation opening 12 and / or eaves ventilation opening 18 to the outside. Ventilation will be performed inside the wall. In addition,
The indoor ventilation, the attic ventilation, and the in-wall ventilation on the upper and lower floors described above can be performed individually, and the respective ventilation functions are combined with each other to purify and circulate the air throughout the building. It is something that will be done. In order to improve the durability of buildings, especially wooden houses, it is necessary to take moisture and dew-proof measures.According to the structure where air constantly moving like this ventilation system is exposed to various places, a drying effect is expected. This can improve the durability of the building.
