Piles - Energy pile

The energy pile, also called "heat exchanger pile", is a pile equipped with individual or several pipe circuits in order to enable exchange of heat with the surrounding soil. The function of energy piles is dual. The first function consists of transferring load from a construction into the bearing layer. The secondary function is the use as heat exchanger with the soil. Energy piles are installed either using soil displacement techniques (see 'Construction sequence'), or soil excavation systems.
