The City of Guelph recently received a $20,572 utility incentive check from Union Gas for specifying energy recovery HVAC dehumidification equipment in the indoor pool area of its renovated Victoria Road Recreation Centre (VRRC).

The NP-50 “Protocol” 50-ton Seresco HVAC dehumidifier heats, cools and dehumidifies the 6,873-square-metre (22,500-square-foot) VRRC natatorium area, which features a 50m competition pool and a 25m teaching pool.

Manufactured by Seresco Dehumidifiers of Ottawa, the equipment qualified the City of Guelph for Union Gas’s Custom Engineering Projects section in its Commercial/Industrial Energy Efficiency Incentive Program.

Guelph will also save an estimated 102,860 cu. m. (3.6 million cu. ft.) in annual gas savings versus the previous system, according to BIN data provided to Union Gas by Kilmer Environmental, the Mississauga, Ont.,-based manufacturer’s representative for Seresco.

Energy savings are generated mainly from recovering compressor waste heat to provide free pool water heating and by using exhaust air to preheat incoming outdoor air. The previous HVAC design consisted of supply and exhaust ventilation air handlers, which was commonly used in natatoriums when the VRRC was designed in 1974.

Consulting engineer firm Smith & Andersen led the custom engineering design team, while Brenner Mechanical was the installing contractor.

“We promote energy efficiency with many programs and reward customers with incentives when they use high efficiency, energy recovery and other technologies that help conserve energy and preserve the environment,” said Ian Dunbar, commercial and industrial account manager for Union Gas.

“The use of state-of-the-art heat recovery dehumidification equipment has significantly increased our energy efficiency while also providing Guelph citizens with a much-improved indoor air quality and comfort in the indoor pool area,” added Bryan Ho-Yan, corporate energy program manager for the city.
