www.raic.org / 2011 Energy Efficient Calgary Child Development Centre 18 ■ ARCHITECTURE CANADA makes child’s play of sustainable opportunities
By Christopher Guly Architect: Kasian Architecture Interior Design & Planning Ltd. Photos: Robert Lemermeyer Considered to be one of North America’s most heavily instrumented buildings, the University of Calgary’s Child Development Centre is also arguably one of the continent’s most energy effi cient. The 12,000-square-metre facility has about 30 different energy-effi cient features, according to Jim Love, FRAIC, a professor and Chair of Sustainable Building Technologies at the university’s Faculty of Environmental Design, who led the energy systems engineering team during the design phase of the centre, which opened in 2007. It has one of the largest photovoltaic arrays integrated into a Canadian building that can produce 40,000-kilowatt hours of electricity. Situated on the south side of the building, the array is mounted on windows with the photovoltaic panels serving as shades to reduce peak solar gain and thus lowering the building’s energy consumption, explains Love. By extending the panels on frames from the building’s wall system, air is allowed to fl ow over the panels to help cool them and generate more electricity. Elongation of the building along the east-west axis allows for more effective use of solar shading, adds Love. In terms of the building envelope, most of the walls carry an R-20 rating and insulation is placed in a separate layer outside the structural wall, which avoids any accumulation of moisture. “There’s a continuous thermal layer outside the structure of the building, which has been described as a perfect wall system,” explains Love. Certifi ed LEED platinum in 2007, the Child Development Centre (CDC) is 55 per cent more effi cient continued on page 22 ARCHITECTURE CANADA ■ 19 www.raic.org / 2011
