In this paper, a calculation method of the heat transfer in the indirect heat exchange type steel pile for the GSHP system was developed and its reproducibility was confirmed by comparing calculated values with actual measurements. First, the effective heat conductivity of the surrounding soil was evaluated by applying the calculation method of the design and performance prediction tool for the GSHP system. The result was 1.5 W/m/K in comparison calculated temperature variations returned from the ground heat exchanger with a measured one. Next, a calculation method of the heat transfer in the indirect heat exchange type steel pile was shown and values calculated with the method was compared to the actual measurement. As a result, it was demonstrated that calculated temperature variations returned from the ground heat exchanger reproduced those of measured in the case where steel piles with both diameter 400mm and 165mm were used.
