Building NX

Building NX at Humber College is Passive House certified and the first retrofit in Canada to achieve the Canada Green Building Council’s (CaGBC’s) Zero Carbon Building–Design certification.

Through a deep retrofit, it has been transformed into the most energy efficient building on the Humber College campus, and one of the most energy efficient buildings in North America.

Globally, buildings are responsible for 40% of annual energy consumption and up to 30% of all energy-related greenhouse gas emissions. Retrofits to existing buildings have tremendous potential to positively impact climate change, however, challenges such the cost of using emerging technologies and non-standard business practices as well as disruptions can deter some building owners.

As the first Passive House retrofit of its type in Canada, the Building NX project offers great insight to engineers, architects and facility owners. Building NX showcases Canada’s readiness to retrofit buildings to zero carbon and make a positive contribution to global climate change efforts.

It demonstrates the value of investing in industry-leading energy efficiency methodologies, like Passive House and Zero Carbon Building standards, to achieve long term benefits.
