Toronto, Ontario (June 3, 2022) – PCL Construction is pleased to announce that two PCL projects received national green building awards at the Canada Green Building Council’s Building Lasting Change conference. The Roam Transit Operations and Training Centre, located in Banff, Alberta won the Zero Carbon Design Award and the Ken Soble Tower at 500 MacNab, located in Hamilton, Ontario won the Deep Carbon Retrofit Award. Both awards recognize teams that construct projects that demonstrate climate leadership through innovative carbon reduction strategies and optimal building performance.

“The Roam Transit Operations and Training Centre and the Ken Soble Tower at 500 MacNab  are leading edge projects that demonstrate that buildings can be decarbonized now,” said Thomas Mueller, CAGBC President and CEO. “The Green Building Excellence award category recognizes the teams responsible for delivering projects that exemplify carbon leadership and an exceptional commitment to sustainability. We congratulate PCL Construction and their partners on their achievements with these two outstanding projects.”

The Roam Transit Operations and Training Centre sets an example for zero carbon buildings. The centre is one of the first transit storage and maintenance buildings to achieve Canada Green Building Council Zero Carbon Building – Design Standard certification. It integrates several low carbon technologies: ultra-efficient mechanical systems, a super-insulated building envelope, district heating, a biomass waste-to-energy operation, solar photovoltaics and electric bus charging. The facility is considered the greenest building in the town of Banff, which is located in Banff National Park, a UNESCO World Heritage Site in the heart of Canada’s Rocky Mountains.

Originally built in 1967, Ken Soble Tower at 500 MacNab is an 18-story, 146‑unit affordable seniors’ housing complex with a three-story annex. Ken Soble Tower is the first retrofit of its kind in North America and the largest residential retrofit in the world to achieve certification under Passive House’s internationally recognized EnerPHit program for buildings that meet ultra-low energy standards. This high-performance, ultra-low-energy rehabilitated building has seen a remarkable 94% reduction in greenhouse gas emissions. Revitalized into an affordable living space for seniors, the tower prioritizes occupant comfort, affordability and climate resilience.
