A review on the performance of geothermal energy pile foundation, its design process and applications

Geothermal energy piles (GEPs) are an environmentally friendly energy source which utilise the low-grade heat energy present in the shallow earth surface to provide heating and/or cooling to the supported structures e.g. buildings. The heat is extracted from or injected into the ground through the circulation of heat carrier fluid that flows in energy loops attached to the reinforcement cage of the pile foundation elements. Utilising the GEP...
