The air circulation wall is a triple envelope and double air layer system of outside walls and roofs. Its midst envelope is a thermal insulation board and divides the wall into two air layers. Since its outer air layer works like as a solar collector, this system increases indoor air temperature in winter under closed air circulation. In summer, its open air circulation exhausts hot air to the outdoor. Many Japanese wooden houses with this air circulation system have been constructed. However, many problems are remained for its optimum designing such as the precise prediction of thermal characteristics and air distributions in the layers. This paper investigates the air distribution and thermal performance of the air circulation wall through real-size model experiments and numerical analysis by means of computational fluid dynamics.
