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.
The heat exchange capacity of the energy pile depends on the thermal resistivity of the pile and the surrounding soils. The consequently, their thermal behaviour could be different. The pile Lennon et al., 2009; Wood et al., 2010) is not in good agreement with the theoretically calculated value.
