Diverso Energy and Mattamy Homes Announce Joint Venture to Advance Sustainable Homebuilding across Canada

Strategic partnership brings benefits of geothermal energy to new homeowners

TORONTO, May 21, 2025 /CNW/ - Diverso Energy ("Diverso"), Canada's leading geothermal Energy-as-a-Service (EaaS) provider and Mattamy Homes ("Mattamy"), one of North America's largest privately owned homebuilders, today announced a joint venture that represents a significant milestone in the evolution of sustainable homebuilding in Canada.

Through this newly formed partnership, Diverso will be the exclusive provider of geothermal services to select Mattamy residential developments across Canada, spanning a range of single-family homes, townhouses, and multi-family mid-rise and high-rise developments.

The partnership makes possible lower-emission communities without compromising affordability, homeowner experience or aesthetic design. Leveraging Diverso's turnkey EaaS geothermal model, select Mattamy homes will now feature fully electrified, emissions-free heating and cooling, with unique benefits such as whisper-quiet operation and greater outdoor deck space thanks to more compact HVAC systems.

"Each of us brought half the solution," said Tim Weber, CEO, Diverso Energy. "It took trust and shared vision to bring the partnership together, which will greatly accelerate the adoption of geothermal technology in residential developments across Canada."

The announcement builds on Mattamy's efforts to reduce carbon across its communities. Mattamy has committed to achieving a 10% greenhouse gas reduction in its FY2025 sold homes as compared to code-built homes—representing a 31 percent reduction from a typical resale home built in 2005/2006.

"We've taken what was once a niche, custom energy solution and integrated it into our mainstream production model over the past several years," said Brad Carr, CEO of Mattamy Homes Canada. "It's evolved into a scalable offering, and our joint venture with Diverso enables us to use the proven, reliable technology to deliver numerous operational benefits to thousands of Canadian homeowners at no additional cost to them."

Both companies intend their partnership to serve as a benchmark for the broader development community, offering a real-world case study in how to meet the demands of increasingly strict building codes—without sacrificing the bottom line.
