Geothermal Innovation Powers Historic Transformation at Evergreen Brickworks
When Evergreen set out to transform the Don Valley Brick Works — a former 19th-century industrial site turned cultural landmark — they had one ambitious goal: make it carbon neutral. But upgrading century-old heritage buildings while maintaining historical integrity presented serious design challenges.
With limited space for a traditional geo-exchange system, the team turned to Geosource Energy, who installed 40 angled boreholes beneath the site’s largest building using advanced vertical drilling techniques. The result? A powerful geothermal system now supports heating and cooling for over 53,000 square feet of event, retail, and community space.
“We’re proud to be a living lab,” says Facilities Director Ali Anvari. “This project combines clean technology, heritage preservation, and community building in one.”
And they’re not stopping there. With solar thermal panels and battery storage on the horizon, the Evergreen Brickworks is paving the way for future cities — right in the heart of Toronto.
