GeoExchange System

Built in 1998, the Visitor Center has "green design" features that reflect a commitment to the environment, including passive solar, the use of recycled and local materials, and a GeoExchange heating and cooling system.

This system lowers energy consumption by using the earth’s constant underground temperature (about 55 degrees Fahrenheit in the Northeast) to help keep the building warm in the winter and cool in the summer.

The GeoExchange system does this through heat pumps and air ducts, which transfer heat energy from the earth to the building in the winter, and from the building back into the earth in the summer. As a result, the temperature inside is always around 70 degrees.

This system doesn't use any fossil fuels, helping reduce pollution. It also requires less electricity than a conventional boiler, saving the Preserve money.
