PROBLEM TO BE SOLVED: To add an air circulation structure for raising air conditioning efficiency of a building after an extension building is constructed, and enhance interior comfort and energy saving of the extension building. SOLUTION: The extension building is constructed by removing a roof member from an existing building, installing a new wall member and a roof member to surround the outer circumference and the top of the existing building, the new wall member is extended from the existing building to a story extended above the existing building, a new floor member is installed on the ceiling member of the uppermost story of the existing building and a living space is formed between the new floor member and the new roof member. The side wall of the existing building comprises an indoor side wall substrate and a finishing board remaining after the exterior wall material and heat insulation material are removed. The new wall member comprises an exterior wall material and a heat insulation material disposed opposite to the wall substrate and the substrate board. A ventilation space is formed between the side wall of the existing building and the new wall material and between the ceiling member and the new floor member. A circulation unit for circulating hot/cold air to the ventilation space is installed in an attic space formed by the new roof member. COPYRIGHT: (C)2008,JPO&INPIT |
