Geothermal Heating and Cooling

Heating and cooling is one of the largest uses of energy in a building.  By utilizing the earth’s relatively constant temperature (55° F), buildings can reduce this energy costs by 40% to 70%.  The system is composed of four major parts:

  1. circulating pumps & back-up boiler
  2. closed loop vertical field
  3. supply & return pipes
  4. heat pump in each housing unit.

The system circulates water through the ground in 300-ft.-deep pipes to either remove or add heat from the heat pump.

Besides the sustainable advantage of using less energy to operate this system, it does not require a large cooling tower on the exterior of the building, thereby reducing the impervious surfaces and allowing for more open space, which helps with the urban heat island effect.
