Martin Methodist College employs Geothermal Heating and Cooling in the Gault Fine Arts Center and the Andrews Science Building!
How does that work exactly?
A series of connected pipes buried in the ground circulate water to absorb heat from, or relinquish heat to, the surrounding soil, depending on whether the system is providing heat or cooling. In other words, the system uses the earth as a heat source during winter and a heat sink during summer.
Geothermal heating and cooling produces 75% to 85% less carbon dioxide emissions than gas and oil produces. For example, a 1,500 square foot house in Westchester, NY heated with oil burns 750 gallons per year, which equates to an output of about 17,000 pounds of carbon dioxide. The same house heated with geothermal technology uses 7200-kilowatt hours of energy, equivalent to roughly 4,500 pounds of carbon dioxide. That’s a yearly reduction of 12,500 pounds of Co2, the equivalent to removing one car off the road for an entire year!
