Using solar heat energy has been paid attention to as effective natural energy use. In this study, we deal with air-based solar heat system, which is used for not only ventilation but heating and hot water supply by hot air.

In Japan, this system has been quite popular and installed into many buildings, but there is a few survey on the system by precise measurement. Then, we started the survey by building three huts with different specification and measure precise data of these in same weather condition. So we can analyse heat balance in these huts. Heat collection, thermal environment and heat storage are very important in the system. Especially, to use stored heat in night time is difficult because the solar heat is collected in the daytime only. The purpose of this research is to make some suggestion to improve the system by the measurement.
