Scotia Plaza’s 40 King St. W. building in Toronto is now the largest certified zero-carbon building in Canada, at more than 1.5 million square feet.

The property, which has a transition plan in place to remove all carbon-intensive mechanical systems over the next 18 months, has earned a Zero Carbon Building – Performance v2 Certification from the Canada Green Building Council (CaGBC).

The project included the installation of high-performance chillers, automated controls for thermal storage tanks to offset cooling during peak hours and an updated building automation system. Green roofs and lighting upgrades have also promoted energy conservation for the property.

Beyond the building systems, the property, which is owned by KingSett Capital, Alberta Investment Management Corporation (AIMCo) and James Richardson & Sons Limited (JSRL), is offsetting other emissions generated onsite using Gold Standard certified carbon offsets. The building has also achieved the largest Fitwel certification in Canada for a multi-tenant base building and holds LEED Platinum and WiredScore Certified: Gold environmental certifications.

“KingSett’s achievement validates that zero carbon buildings – whether new builds or retrofits – are both technically and financially feasible for owners willing to innovate and invest in a low carbon future for Canada,” said Thomas Mueller, president and CEO of Canada Green Building Council.
