This is a community recreation complex with outdoor park amenities. The Audley Recreation Centre includes an aquatic centre comprised of leisure and competitive pools, multi-purpose community rooms, a childcare centre, a gymnasium, and administrative spaces. Originally targeting LEED Silver Certification, this project has now achieved LEED Gold Certification. The current LEED energy modeling results predict a 52% energy use reduction resulting in a 38% annual energy cost reduction.
The energy efficient building mechanical systems feature a solar wall in lieu of a traditional rooftop screening to pretreat incoming outside air, exhaust air heat recovery systems on both the change room rooftop unit and indoor pool dehumidifier, and demand control ventilation controls to minimize energy consumption while still providing superior indoor air quality. The domestic hot water system includes a 36-panel solar array on the roof to preheat the domestic hot water before entering the condensing water heaters and all plumbing fixtures are low flow type. Fan and pumping energy is reduced through the use of variable frequency drives, including the pool water recirculation pumps, and the design incorporates condensing boilers sized for future expansion of the facility. All building mechanical systems are sub-metered and the information is displayed on a sustainable kiosk in the main lobby to enhance user awareness and education on the facility's energy efficiency and water saving incentives.
Electrical systems feature a low-voltage lighting control system complete with occupancy sensors, daylight harvesting sensors, and low-voltage controls to minimize lighting power density. High efficiency luminaires with low mercury fluorescent lamps have been installed throughout the facility to optimize lighting performance. An emergency lighting inverter system is installed to supply power for all emergency lighting for a period of no less than 30 minutes. An electronic metering system has been implemented into the power distribution and integrated with a sustainability kiosk which measures plug loads, interior lighting, exterior LED lighting, pool equipment, mechanical equipment, and gymnasium loads etc. to display the building's performance. A two-stage addressable fire alarm system has been installed so that facility management can investigate alerts prior to the fire alarm system going into full alarm and mitigating evacuation of the entire facility. The facility is powered by a utility-owned medium voltage pad mounted transformer feeding a customer owned 600V switchboard and is sized for future expansion.
