The Building NX retrofit at Humber College, Toronto, has been awarded the Zero Carbon Building—Design certification by the Canada Green Building Council[2] (CaGBC). It is the first retrofit in the country to achieve this certification.

The original building envelope, built in 1989, consisted of aluminum curtain walls and spandrel panels, as well as a glass vestibule. The retrofits required a new envelope to achieve the thermal energy performance requirements of CaGBC. The college was able to achieve a design that will see Building NX use 70 per cent less energy than before, making it the college’s most energy-efficient building.

Work on the 4484-m2 (48,269-sf) five-storey building includes the installation of new triple-pane windows. Energy-efficient upgrades to the lighting, heating and cooling systems, and a new 25kW solar photovoltaic (PV) system were also completed.

“One of the biggest challenges to reducing greenhouse gas (GHG) emissions in Canada is finding ways to heat buildings at a reasonable cost without burning fossil fuels,” said Spencer Wood, Humber College’s director of facilities management. “Humber wanted to be an example to the Canadian design and construction industries on how a deep energy retrofit can contribute positively to our country’s climate.”

Renovations to the building, which were designed by B+H Architects[3] and Morrison Hershfield[4] and constructed by Bird Construction[5], began in May 2018 and are scheduled for completion this summer.
