Energy piles, combined ground source heat pumps (GSHP) with the traditional pile foundation, have the advantages of high heat transfer efficiency, less space occupation and low cost.

The energy pile represents an embedment of heat exchange pipes into the pile body. In this way, it can serve as a vertical heat exchanger in addition to its primary function of supporting the building. The additional land use and construction costs related to the conventional vertical boreholes of the GSHP system can thus be saved.
Energy piles offer a promising and eco-friendly technique to heat or cool buildings. Energy piles can be exploited as ground heat exchangers of a ground source heat pump system. In such application, the energy pile and its surrounding soil are subjected to temperature changes that could significantly affect the pile–soil interaction behaviour.
In this study, temperature changes of the energy pile were constrained to be within a range of 5–40 °C. This range serves as an input into the thermo-mechanical analysis of the energy pile foundation, resulting in a one-way coupling between the thermal analysis of the whole system and the thermo-mechanical analysis of the energy pile foundation.
As shown in Fig. 5 (a), for the case in unfavourable ground conditions, the computed results corresponding to the actual pile length of 30 m underestimated the daily-averaged rate of heat exchange by about 25% for both the modes of heat extraction and injection. To improve the situation, an equivalent pile length was calibrated.
