18 July 2026

Canada uses the most carbon per capita in the G7. A big share of that comes from the buildings we already live and work in — some 20 million of them across the country, most drawing heavily on fuel and grid power just to stay comfortable in our temperate climate.

The conventional fixes fall short

The usual answers — bigger HVAC, more equipment — are expensive to install and carbon-heavy to run. And genuinely solar-passive design has, until now, been out of reach for ordinary homeowners: custom, costly, and hard to even picture on the house you own.

The lowest-carbon square foot is the one that's already built.
