Greening buildings to get to net zero —

Building heat is the second-largest source of Ontario’s emissions. Energy conservation, combined with adopting a mix of clean heating and cooling technologies, is the most cost effective and resilient way to achieve net zero.

Using less through energy conservation

Energy efficiency programs and building code changes for more sustainable buildings.

Transitioning to renewable energy sources

A mix of renewable power, renewable natural gas and hydrogen to sustainably energize HVAC systems more reliably and cost effectively.

Adopting cleaner HVAC systems

Heat pumps, hybrid heating, solar and geothermal for homes; clean, reliable technologies for larger buildings, like geothermal and district energy.
