Geothermal The primary source for heating and cooling the building is derived from constant 55 degrees maintained by the earth mass below the site. A system of pipes loops temperature transfer fluid through twenty 220’ deep shafts and into the building’s heat pumps. Heat is brought into the building in winter and is transferred to the earth in summer
Energy Recovery Energy recovery wheels rotate between the incoming outdoor air stream and the building exhaust air stream. As the wheels rotate, a percentage of the heat and moisture differential is transferred from one air stream to the other. Consequently, the outdoor air is pre-conditioned, significantly reducing the capacity and energy needed from the mechanical HVAC system.
