The aim of this study is to evaluate the performance of the GHP system with 150 energy piles for a commercial building. In orderto demonstrate the feasibility of a sustainable performance of the system, simulations were conducted over 1-year and 20-year periods, respectively. The 1-year simulation results showed that the maximum and minimum temperatures of brine returning from the energy pil es were 23.80℃ and 7.90℃, which were in a range of design target temperatures. In addition, after 20 years’ operation, the se returning temperatures decreased slowly to 23.05℃ and 6.98℃, and f inally reached to stable state. The results also showed that the energy piles injected heat of 65.6 MWh to the ground and extracted hea t of 96.0 MWh from the ground, respectively. Also, it is expected this GHP system with energy piles can operate with average SPF of more t han 4.15 for long term.
