This paper reports on test house measurements and simulated prediction for the proposed a low energy house with air-circulation in brick walls. Distribution of thermal mass, arrangement of heat gain/exhaust elements, combination of other devices and operation scheme control the indoor thermal environment and reduces of air-conditioning load. The first stage, the thermal performance of a brick house was simulated to compare with other types of wall structures, and it was possible to improve the thermal performance of a brick house with utilization of heat gain/exhaust elements. The next stage, a test house was constructed to validate experimentally the effect of proposed devices. Direct solar gain and Trombe wall effect are the object in winter in terms of heat gain. Earth cool tubes and solar chimney effect by Trombe wall are measured to estimate the cooling amount. We proposed a real size model house with air-circulation in brick walls combined with a solar air-heater, Trombe wall and cool tubes, and the thermal performance of it was simulated as the third part of this paper. Experimental results on the test house were used to validate the accuracy of the simulation programs. As for the seasonal heating/cooling load, the brick house with air-circulation was estimated about 20% less than a normal wooden structure house.
