For apprehending the performance of solar heating system, it is important to understand the relations of heating load and the system elements such as heat collection, heat storage, insulation, and so on. In this study, the measurements in the 3 buildings made progress at the same time for comparing the influence by these elements on the system, because the effect of the solar heating system is fluctuated by weather conditions. This paper describes outline of the measurements and specifications of the two test buildings that the air-based solar system is installed in. It also shows the changes of the heat flow on underground surface by installing the insulation under basement, changing the area of solar heat collector, or applying the water-pack as the additional heat storage.
