PURPOSE:To decrease practicably heat loss by a method wherein a building structure is heated or cooled by the operation of an air conditioner during a room is not used, then an air which is blown-off by the operation of another air conditioner is still heated or cooled for the using period of a room by the building structure which is previously heated or cooled. CONSTITUTION:In case of a room 3 is not used in the night time, an air conditioner 11 is operated, then a hot-air is blown-off into a ceiling 5 from a blown- off port 11a of the air conditioner. The hot-air is directly distributed throughout in the ceiling 5, further supplied into the room 3, at this time, a fan 17 is kept under stop condition. The ceiling 5 and the room 3 are heated by the hot-air, the heat is accumulated in slabs 14, 2 made of concrete. Subsequently, when the room 3 is used in the daytime, an air conditioner 13 is operated, the air conditioner 11 is stopped, at this time, the air in the ceiling 5 is blown-off into the room 3 by the operation of a fan 17. The hot-air blown-off from the air conditioner 13 is supplied into the room 3, a part of the blown-off air is introduced into the ceiling 5, then heated with the accumulated slab 14, the hot-air is blown- off into the room 3 from a blown-off port 18 with the fan 17, thus the inside of the room 3 is heated.
