Distribution system A distribution system moves the heating and cooling energy throughout the building. The HVAC system can take many forms in commercial applications, including traditional heat pumps, Variable Refrigerant systems, or central plants with fan coils/ air handlers. It is up to the building design team to find the best solution for the intended…

Ground-coupled heat exchanger (GHX) A ground-coupled heat exchanger is underground piping that is in contact with the earth to store or retrieve energy. There are both closed and open-loop underground piping systems.

HVAC SYSTEM A HVAC system, such as a heat pump, is located inside the building and uses compression to either create heating or cooling. It is connected to the ground-coupled heat exchanger (GHX) and circulates a fluid through the GHX in order to store/retrieve energy
