The City of St. Albert’s Akinsdale and Kinex arenas were retrofitted in 2013, with energy conservation measures focused on their heating and automation systems.
Before the retrofit, snow was melted by directly applying 120ºF water to the melt pit. A heat recovery coil was since installed to capture the waste heat generated from cooling the ice to melt the snow. The existing atmospheric combustion boiler used to heat the water was also replaced with a condensing boiler, increasing its efficiency from 65% to 92%. Additionally, the hot deck set point temperature was reduced from 8ºC to 2ºC, which will reduce the ice plant’s run time by 30%. The $63,650 project will pay itself back in only 2.6 years, with annual savings of $14,629, 1,520 GJ in energy, and 115 tonnes of emissions.
Town of Okotoks
Okotoks completed a multi-facility energy efficiency retrofit in 2014, which included their Recreation Centre, Centennial Arena, and Fire Hall. With operational cost savings expected to be as high as $50,000 per year, the payback period is estimated to be 6.7 years. The project will also save the Town 4,268 GJ of energy and 327 tonnes of GHG emissions per year.
City of St. Albert
As part of the Municipal Energy Manager Program, the City of St. Albert has hired a Municipal Energy Specialist that will benchmark municipal facilities, identify energy savings opportunities and implement greenhouse gas emission reducing projects.
