Fenestration West Magazine, one of Western Canada's leading voices on windows, has awarded Cascadia Windows Ltd. with its 2013 Project Excellence Award. The award recognizes Cascadia's involvement in retrofitting The Belmont, a 13-story condominium on Vancouver's west side.
 
Originally constructed in 1986, The Belmont is a typical build of condominium found in the Kerrisdale Neighborhood of Vancouver. It features a window-to-wall ratio of 50%, taking advantage of panoramic views spanning Vancouver Island to the city's downtown core. The existing windows consisted of double glazing with air fill and no low-e coatings in non-thermally broken aluminum frames, accounting for significant heat-loss.
 
These were replaced with 300A Series triple-glazed fiberglass framed windows, improving the U-value from about U-0.55 to U-0.17. The windows are argon filled and feature low-e 366 and low-e 180 for optimal performance.
 
 
Existing exterior walls were exposed cladding, with an effective R-value of R-4. For the deep energy retrofit, walls were over-clad with mineral wool insulation behind stucco and metal panel cladding. The cladding and insulation were held in place using 3.5 inch Cascadia Clips, significantly reducing thermal bridging, resulting in an overall effective R-value of R-16 for the exterior walls.
 
Energy savings as a result of the retrofit are estimated at 90% for in-suite space heating energy and 20% for overall building energy. This amounts to heating cost savings of $16,000, cut from $18,000 to just $2000 per annum.
