Patent ID: 7992631

Claim:
A temperature control system for a building, the temperature control system comprising: a thermal collection system comprising a plurality of coils including at least one fluid channel with fluid contained within the at least one fluid channel, the thermal collection system configured to heat or cool the fluid within the at least one fluid channel, and the thermal collection system including heat conductive metal sheet material extending from a position above a roof decking of the building to a position below the roof decking, wherein the heat conductive metal sheet material is in direct contact with the at least one fluid channel below the roof decking; a first underground heat sink configured to receive the fluid from the thermal collection system, wherein the first underground heat sink absorbs heat from the fluid in order to heat the first underground heat sink; a second underground heat sink configured to receive the fluid from the thermal collection system, wherein the fluid absorbs heat from the second underground heat sink in order to cool the second underground heat sink; and a heat exchanger configured to receive fluid from the first underground heat sink in order to heat the building, the heat exchanger also configured to receive fluid from the second underground heat sink in order to cool the building.
