An innovative waste heat recovery system at the Hershey Centre implemented by Energy
Management staff from the City of Mississauga's Facilities and Property Management Division is
estimated to reduce greenhouse gas emissions by 160 tons - equal to removing 48 cars from
Mississauga roads per year.
How it Works - Waste Heat Recovery System
Waste heat is taken from the hot ammonia refrigerant used to make rink ice. This system
recovers waste heat to preheat water and ventilation air. The recovered heat is used to preheat
hot water for the facility's showers.
Additionally, the ice resurfacing machines for flooding the ice rink now use recovered hot
water instead of heating cold municipal water. The total cost of $289,659 will be recovered in
Innovation in Action
The Energy Management project for the Hershey Centre was designed to enhance efficiency and
ensure low operating costs with maximum heat recovery. Waste heat recovery is less common in
retrofits to existing facilities such as the Hershey Centre due to complexity of design and
