A building automation system was installed to control the new equipment and interface with the old, optimizing operations throughout the ice rink. Overall energy consumption de creased significantly. In the first year, electric demand decreased by 1.169 million kWh, or about 37 percent. Gas consumption decreased by 1,150 Mcf, about 7 percent. In addition, over 2 million gallons of water are saved annually.
Snow accumulated by resurfacing the ice is melted with waste heat from the system and refrozen.
There are numerous environmental benefits associated with this project. Estimated annual emissions reductions equal 9,195 pounds of nitrogen oxides, 2.5 million pounds of carbon dioxide and 24,650 pounds of sulfur dioxide. Due to all the benefits from the renovation, the project was a success.
