Using Geothermal Exchange Systems to Achieve Zero Net Energy in Cold Climates
Geothermal heating and cooling exchange systems are proving to be a leading technology for achieving zero net energy consumption in cold climates. Geoexchange systems (also known as “geothermal heat pumps”) reduce energy consumption by using the earth to store heat and greatly improve HVAC efficiency. Using a network of closed-loop tubes buried deep underground, geoexchange systems require extensive planning, soil testing, and proper load design to function as intended, especially in energy-intensive lab environments. But when used with other strategies, they can play a significant role in reducing a facility’s HVAC-related energy use and carbon footprint.
