Berczy Glen Development

Salas O’Brien partnered with Mattamy Homes to design a net zero carbon system that is 3.5 to 4 times more efficient than conventional natural gas alternatives for the Berczy Glen development. This 327-home development is the first residential neighborhood in Canada to have its heating and cooling needs met by a central geothermal system.

Homeowners are expected to see a 30-50% reduction in their monthly utility bills. The geothermal system consists of 170 vertical borehole loops, 850 feet deep, distributed entirely under neighborhood streets in 12 pods, connected by a two-mile ambient water loop. Circulation pumps serving the loop and individual pods are housed in subgrade vaults, eliminating visible infrastructure. The system will be maintained by Enwave Energy Corporation, demonstrating the feasibility of community-scale geothermal systems.
