How Bylaws Can Promote the Greening of Heating and Cooling in Multi-family Buildings

TORONTO, Sept. 15, 2023 /PRNewswire/ – Subterra Renewables is pleased to announce an upcoming webinar on September 21st that explores the innovative intersection of GeoExchange systems, city bylaw and approvals processes, and the mechanical penthouse in building design.

Lucie Andlauer, CEO of Subterra Renewables, emphasizes the importance of this webinar, stating, “Since geo-exchange systems can avoid rooftop mechanical equipment, municipalities can incentivize implementation of geo-exchange by allowing developers to repurpose penthouse space. Minor adjustments to site-specific zoning bylaws during the approvals process can unlock this valuable real estate without changing the overall massing of the building. In other words, the building looks very similar, but has much lower emissions, and it costs municipalities nothing.”

Don’t miss this opportunity to gain insights into sustainable urban development and discover the potential for unlocking valuable real estate in your projects.
