A winning net zero carbon retrofit by B+H

The site of Humber College Building Nx in Toronto

The Canada Green Building Council (CaGBC) recently announced the winners of the 2020 Leadership and Green Building Excellence Awards. The winner for the category of Green Building Excellence – Existing Building is the Humber College Building Nx in Toronto.

For the deep energy retrofit, airtightness and thermal continuity of the building envelope offer improved energy results.

An ambitious deep energy retrofit at Humber College’s North Campus has achieved Zero Carbon Building Standard – Design certification, with the airtightness and thermal continuity of the building envelope driving improved energy results, while investment in lighting, temperature control and air quality brings increased occupant comfort. 

The college was built in 1989 and had been experiencing systematic building envelop failure for some time with air filtration and water penetration issues. The zero-carbon retrofit not only addressed these issues, greenhouse gas emissions  (GHG) were also significantly cut. The campus also installed photovoltaic cells, it uses 70 percent less energy than it did before, thus helping to make the campus one of the most efficient in North America. This is vital as the built environment contributes 17 percent of GHG emissions and Canada is committed to eliminate all GHGs by 2050. Watch the video announcement here.

These awards recognise individuals and organisations that demonstrate outstanding industry leadership and have made significant contributions to CaGBC’s mission to advance green building in Canada. Winners will be recognised throughout Building Lasting Change 2020, taking place online on five consecutive Tuesdays from September 22 to October 20. Green Building Excellence winning projects will be explored in a series of Lunch and Learn sessions starting late October.
