Geothermal heat pump systems transfer heat from the earth to buildings. At a certain point underground, the air remains at a constant temperature year-round (about 50 degrees Fahrenheit), requiring a minimal amount of energy to heat the building to 65-70 degrees, while providing a source of cooler air in the warmer months.
The type of geothermal heat pump system circulates water in a closed loop through vertical wells in the ground. The water is then circulated through the school building, where highly efficient heat pumps extract heat from the loop to heat the air.
An added benefit of this type of system is its flexibility in keeping learning spaces comfortable. One room can be cooled while another is heated, ensuring all students are comfortable.""
