Today, the City of Toronto announced the eight buildings participating in the Deep Retrofit Challenge (DRC), a competition-style program with up to $5 million in investment from Natural Resources Canada provided through its Green Infrastructure – Energy Efficient Buildings Program.
Through the DRC, grants of up to $500,000 will be awarded to each of the buildings, seven of which are privately-owned, to support deeper-than-planned energy retrofits. The grants will offset the incremental design and construction costs required to achieve maximum greenhouse gas (GHG) emissions reductions.
• 350 Bay St. (Dream Office REIT)
• 723 Bloor St. W. (Dream Unlimited)
• 88 College St. (The Governing Council of the University of Toronto)
• 1-15 Field Sparroway and 2-10 Tree Sparroway (Toronto Community Housing)
• 633 Northcliffe Blvd. (Northcliffe Inc.)
• 177 St. George St. (Dream Unlimited)
• 145 Woodward Ave. (145 Woodward Ave. Inc.)
• 61 Yorkville Ave. (Minto Apartment Limited Partnership)
Launched in 2022, the DRC aims to accelerate emissions reductions from buildings in Toronto and identify pathways to net zero that can be replicated in other buildings across the city. The retrofits will advance the goals of the TransformTO Net Zero Climate Action Strategy, including the City’s ambitious target to reduce community-wide emissions to net zero by 2040, and serve as a catalyst to accelerate deep energy retrofits in support of the City’s Net Zero Existing Buildings Strategy.
Toronto’s community-wide emissions must be cut in half in the next seven years – by 2030 – to reach the trajectory needed to reach net zero by 2040. Buildings are the largest source of GHG emissions in Toronto today, generating approximately 58 per cent of community-wide emissions, primarily from the burning of natural gas for heating and hot water. The City controls only about five per cent of community-wide emissions directly through its own buildings and operations, making a community-wide effort essential to reaching net zero emissions.
DRC participants are currently finalizing their designs. The process includes an integrated design workshop, energy modelling, the final selection of energy conservation measures and payback calculations. To remain eligible for funding, participants must deliver a final design to the City that verifies that their proposed projects will meet all DRC program requirements, including:
• Minimum 50 per cent reduction in the building’s GHG emissions
• Minimum 50 per cent reduction in total energy use intensity
• Payback period of 20 years or less
Retrofits will be completed by early 2025. Once complete, the City will develop and publicly release comprehensive case studies on completion of the retrofits, including the retrofit designs, utility savings, project costs and lessons learned.
Applications for the DRC were accepted from August 26 to October 31, 2022.The City received 14 applications and accepted 11 conditionally, with eight building owners now fully committed.
More information about participants and their projects is available on the City’s Deep Retrofit Challenge webpage.To receive updates about the projects, residents can ask to be added to a mailing list by emailing firstname.lastname@example.org.
