Abstract
This study evaluates the energy performance of an energy pile system as an emerging shallow geothermal technology integrated into an eight-story residential building located in the Saadat Abad district of Tehran. The Taguchi design of experiments method was employed to systematically investigate the influence of key design parameters, including pile depth, pile diameter, and heat exchanger pipe diameter, on the thermal response of the system. Nine design scenarios were developed for an array of sixteen energy piles and analyzed using numerical simulations in the PileSim 2 platform. The results show that pile depth is the most influential factor affecting the thermal efficiency of the system. Under the optimal configuration, the sixteen energy piles were able to supply approximately 97% of the building’s heating demand and 61% of its cooling demand. In addition, a preliminary estimation of carbon emission reduction was performed for the optimal configuration using emission factors reported in the literature, indicating a promising potential for lowering carbon emissions compared to conventional systems. Overall, the findings demonstrate that energy pile systems can meet a substantial portion of residential heating and cooling demands under Tehran’s climatic conditions and serve as an effective solution for improving energy efficiency in buildings.
