The purpose of this project is to investigate how much peak electric demand in the day that is cut down by applying earth heat storage system using surplus electricity at night and photovoltaik system to small size buildings and residences. We constructed a residence so call "the Energy Producing & Saving House" in Kumamoto City. We have been carrying out this study since 1994. The results obtained at this project are as follows ;The results of electric generation efficiency during the period from 1996 to 1997 were presented.Regression Analysis was carried out to predict electric generation of the PV system under various weather conditions.After examining the results of the experiments mentioned above, the overall efficiency of the earth heat storage system is estimated to be approximately 1.5 times of electrical energy consumption of the chilling unit at night. It became clear, that the earth heat storage system serves as a heat source for space heating or cooling during daytime. For electlical power consumer In residences or small-scale buildings, the electricity costs can be reduced due to the lower user rate at midnight. Moreover, the system also alleviates the load on the city's power grid during daytime peak periods.

这个项目的目的是研究通过在小型建筑和住宅中使用地球蓄热系统和光伏系统，在夜间使用剩余电力，减少了多少白天的高峰电力需求。我们在熊本市建造了一座被称为“能源生产和节约之家”的住宅。我们从1994年开始进行这项研究。本项目的研究结果如下：介绍了1996 ~ 1997年的发电效率分析结果。通过回归分析预测了不同天气条件下光伏发电系统的发电量。根据上述实验结果，地球蓄热系统的总效率估计约为制冷机组夜间电能消耗的1.5倍。很明显，地球蓄热系统在白天为空间供暖或制冷提供热源。在住宅或小型建筑中，由于午夜的用电量较低，可以降低电费。此外，该系统还减轻了白天高峰时段城市电网的负荷。
