Glazing leads to daylighting, efficiency at PCL building

“In addition to providing daylighting, the [multifunctional 2000 Skylight on the PCL] also played a large role in the concept of a ‘solar chimney.’ Designed to increase energy efficiency, the ‘chimney’ allows hot air to escape and cool air from the outside to enter the building.” —Lisa Szematowicz, LEED AP, associate product manager, Kawneer Co., Norcross, Ga.

The basics: To mark its 100th anniversary, Canadian-based PCL created the PCL Centennial Learning Centre, Edmonton, Alberta, a building that would serve as the new training and development hub for its companies, embrace sustainable design and reduce environmental impact. Using Leadership in Energy and Environmental Design principles, PCL was able to deliver a striking facility that consumes less energy, resulting in lower operating costs. The building design consisted of 75 percent glazed elements. The PCL Centennial Learning Centre achieved LEED Gold certification, the first private sector building in Alberta to do so, according to officials at Kawneer.
