Energy foundations and other thermo-active ground structure, energy well s, energy slabs, and pavement heating and cooling represent an innovative technology that contributes to environmental protection and provides substantial long-term cost savings and minimized maintenanc e. This paper focuses on earth-contact concrete elements that are already required for structural reasons, butwhich simultaneously work as heat exchangers. Pipes, energy-piles and energy-slabs filled wit h a heat carrier fluid are installed under conventional structural elements, forming the primary ci rcuit of a geothermal energy system. The ground source heat pumpsystem with energy-pile and energy-s lab presented high heating performance due to the stability of entering water temperature from the ground loop heat exchanger. The minimum COPs of the heat pump unit for the energy-pile and energy-sl ab system were 4.2 and 4.5, respectively. These results are higher than the minimum COP certificatio n standard of 3.45 for a closed ground loop heatpump unit.
