As extreme weather events accelerate, a new report by the Pembina Institute, Healthy Buildings in a Changing Climate, highlights the critical need for retrofitting existing buildings to safeguard Canadians’ health and safety. Deep retrofits are presented as a strategic investment to enhance occupant health and resilience against these emerging climate realities.
Every year, we’re witnessing an increase in extreme heat events and related emergencies, making it imperative to invest in deep retrofits now. Upgrades to ventilation, heating, cooling systems, and building envelopes can significantly improve health and safety for occupants. The report underscores the urgency of retrofitting Canada’s homes and buildings, originally designed for past climate conditions, to address the rising threats posed by extreme heat, flooding, and wildfire smoke. Vulnerable populations, including the elderly, young children, those with pre-existing health conditions—and low-income households—are particularly at risk.
Coordinated efforts from all levels of government, utilities, insurance and investment sectors, and building owners are needed now to mitigate health risks and ensure safe, resilient homes and buildings. The report also emphasizes how deep retrofits not only reduce emissions but also make buildings reliable, climate-safe, and more affordable to heat and cool, offering a high-return investment for Canadians.
