This paper deals with a summary of the GSHP system and the project process, and the anticipated effect of GSHP system. Heat exchange pipes are installed in the PHC foundation. The GSHP system is expected to improve the COP by introducing short term thermal energy storage operation. In this paper, it is shown a condition in the soil as a geologic column, the operating concept, conception drawing, the result of the thermal response test. It is also noted the result of simulation about short term thermal energy storage system of the GSHP system. As the result, annual power consumption of the GSHP and summer season power consumption of the air source Heat Pumps for hot water supply in this model (case2) is estimated 8% lower than usual model (case1).
