Humber College?s retrofitted NX building has been awarded the Zero Carbon Building – Design Certification by the Canada Green Building Council. The NX building is Humber?s most energy efficient building that uses 70 per cent less energy, and it’s the first retrofit in Canada to achieve design certification, according to Canada Green Building.

?Congratulations to Humber College for earning a Zero Carbon Building ? Design certification for their NX building,? said Thomas Mueller, President and CEO of the Canada Green Building Council. ?As the first retrofit to achieve zero carbon design certification, Humber College is showing real leadership and innovation in green building and carbon reduction. The NX building demonstrates that Canada has the expertise and technology now for buildings to reach zero carbon and contribute to global climate change efforts in a meaningful way.? Transforming the NX building required a retrofit that is insulated and airtight. To achieve the thermal energy performance requirements of CaGBC?s new Zero Carbon Building Standard, the original aluminum curtain walls, spandrel panels, and a glass vestibule were replaced.
The new envelope retrofit features high-performance skin and engineered transitions for quality air control to mitigate thermal bridging. In addition, new super-performance windows were also installed for better energy efficiency.
