Ground source heat pump(GSHP) systems is known as environmental friendly and energy saving. Especially a ground heat exchanger is an important unit that determines the thermal performance of a system and initial cost. In design phase of vertical GSHP system, it is recommended that the effective borehole thermal resistance, be determined from in-situ thermal response test. In this study, ground effective thermal conductivity was categorized by a region. As a result of the study, the ground thermal conductivity of national average was analyzed as 2.56 W/mK. The highest regional average of thermal conductivity is 2.68 W/mK in Seoul, and the lowest is 2.28 W/mK in Busan. Also, the thermal conductivity on the coast has been analyzed approximately 30% lower than the average.
