PURPOSE:To contrive to prevent the bedewing and to reduce the heat loss by a structure wherein an air chamber, which communicates to the inside of walls, the inside of floors and the outside air, are provided while a means for supplying the air in the air chamber to the various parts of the building, a means for exhausting the air in the various parts to outside and a heat exchanger are provided. CONSTITUTION:Ventilating layers 6, which communicates the inside of walls, the inside of floors to each other and to outside air, consist of wall ventilating layers 61, floor ventilating layers 64, outside vent holes 62 and communicating holes 63 and 65. Furthermore, the air chamber 3, into which air is collected by communicating to the ventilating layers 6, the exhaustion means 82 for exhausting the air in the various parts within the building to outside and the supply means 81 for supplying the air in the air chamber 3 to the various parts in the building are provided at the suitable location of the building. In addition, said exhausted air and supplying air are head-exchanged with each other through the heat exchanger 9. Owing to the structure as described above, the prevention of moisture condensation on the walls 4 and the floors 5 and the ventilation with a small heat loss can be enabled. |
