Strathcona County Newspaper Article (November 17, 2006 issue)

At about 70 liters per second, gas fire boilers will soon be sending hot water to heat Sherwood Park¹s core. The County Hall, Kinsmen Leisure Centre, Festival Place, Sherwood Park Arena and the county¹s recreation office will be tied into the environmentally friendly system. The Community Energy Centre is projected to eventually heat 600 Centre in the Park condominiums.

Diehl Townsley, manager of facility services for Strathcona County, says this is an opportunity for Sherwood Park to set an example for other communities. “Things have to change and somebody has to take leadership and show what that change can do,” Townsley said.

The boiler room of the Community Energy Centre is not a typical boiler room. It is not dark or dusty and, most noticeably, there is no heat radiating from the large boilers that fill up the space. The lack of heat is proof of how energy efficient the centre is. ”It¹s pretty amazing,” says Jim Manson of FVB Energy Inc. The Energy Centre will send heated water to other buildings where the heat is transferred to the building¹s own system and then the slightly cooler water is sent back to be reheated again. This eliminates the need for individual boilers as well as other equipment like hot water tanks.

Strathcona County predicts the system will reduce greenhouse gases by 18 per cent per year. Manson says not only are the types of harmful emissions reduced but, with this new system, they will be reducing the number of smokestacks from 40 to only two. On top of reduced emissions, the gas boilers can easily be tailored to use other fuel sources as well. County utilities manager Jeff Hutton says the boilers are easily adaptable to other more environmentally friendly fuels and are prepared to do so in the future.
