Abstract: In this paper, we clarified the effectiveness of the heating load reduction, based on measurement results by calculating the amount of heat accumulated by passive techniques. The accuracy of the numerical simulation was confirmed using the actual measurement data. Then we clarified the impact of some passive method such as window area, window specification, double skin and trombe wall. In recent years, the demand for highly efficient insulation and airtightness in a detached house has steadily been increasing. In addition, the utilization of solar heat attracts attention as an efficient method to reduce the conventional heating load. In our project, we proposed a method, which collects and provides solar heat using a passive heating technique in the central air conditioning and circulation system. We set 6 buildings in 6 areas for verification of the heating load reduction effect by utilization of solar heat. These 6 test houses were designed based on a numerical simulation. In addition, it is necessary to mention that these houses have two characteristics: first, the heat exchangers were introduced; second, the air conditioning system for the entire house, including the bottom floor, consisted of only a common heat pump air conditioner. For each house, external temperatures, room temperature and humidity, and the energy consumption used to run these houses were measured starting February, 2015.
