Cooling makes heat. Showers send heat down the drain. Exhaust fans blow it outside. Here’s how building heat recovery in Ontario captures that wasted energy — often the highest-return step in a decarbonization plan.

The cheapest kilowatt is the one you never use. Here’s how envelope, ventilation and low-temperature hydronic upgrades reduce building energy load in Ontario — and shrink the heat pumps you’ll need later.
