Energy piles encase heat exchange pipes in a pile foundation to use geothermal energy. This paper evaluates the constructability and thermal performance of energy piles equipped in a large-diameter drilled shaft. Two energy piles were constructed by fabricating coil-type heat exchange pipes in...

Heat pumps, as a process recirculating environmental heat back into useful heat production, fit the environmental requirements of present global policy. They are very useful tools to reduce the need of fossil fuels in space heating and cooling. The government of the Republic of Korea has...

Energy foundations and other thermo-active ground structure, energy wells, 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 maintenance. This paper focuses...
