PURPOSE:To make full use of the ground temperature by a method wherein the side walls and the ceiling wall of the basement are made to be of double structure, an air flow passage is formed, an air intake port communicating with the open air and an air outlet port for supplying air to a desired section are provided and air is sucked and circulated through the room so as to exchange heat with geothermal heat constantly. CONSTITUTION:A side wall unit 2a is made to be of double structure comprising an outer wall 7 and an inner wall 8. Further, a clearance S' is provided between the outer wall 7 and the inner wall 8, the base sections of the walls 7 and 8 are embedded upright in a concrete base 4 and the air outlet port 16 is formed with a damper 9 pivotally attached to a part 10 of the outer wall 7. Other side wall units 2b and 2c are made to have the same structure as the unit 2a. In addition, a fan is arranged at a desired part of the room so that the open air is sucked into the room through the air intkae port 17 and circulated through a clearances S'2 in the ceiling 3 and the clearance S' in the side wall 2. Moreover, the clearances S'2 or the clearance S' is made to communicate with the residence A above the basement so that heating and cooling operations utilizing the heat exchange between the air in the basement and that in a part of the residence A are performed. |
