A horizontal earth loop under the parking lot stores excess heat that can't be used in the building, and provides heat when refrigeration isn't needed for the ice. The Ice Kube fluid-to-fluid heat pumps heat the swimming pool, heat the fluid circulating through the radiant floor piping in the change rooms, lobby, rink apron and the spectator seats. Snow scraped from the ice during resurfacing and snow at the front entrance is melted as well. The heat pumps also provide hot water for showers and flooding the ice surface. Water-to-air heat pumps heat and air condition the building as required, either drawing heat from the earth loop, or rejecting heat into it. An evaporative fluid cooler prevents the earth loop temperature from becoming too warm.

Natural gas is not used in the building, eliminating the production of approximately 1,000 tonnes of CO2 emissions each year.
