Recently, ground source heat pump systems(GSHP) utilizing annualy stable ground temperature for energy saving have been attracted in many buildings. These systems can achieve higher performance of system by supply more efficient heat source to the heat pump than the conventional air-source heat pump system. But, GSHP systems have disadvantage due to increase of initial installation and boring cost. In order to reduce the initial cost, many researches have focused on the energy-pile system using the structure of the building as a heat exchanger. However, there are few studies on the prediction method of heat exchange rate for energy piles. In this study, the prediction method using the ground heat transfer model and ground heat exchanger model has been developed for the energy pile system using steel piles.
