Climate Resilient Retrofits

Adapting Canada's existing building stock to withstand a changing climate

How can we prepare our homes and buildings to be climate resilient?

This is a question facing communities across the globe, and one that Partners for Action, in collaboration with our partners, is seeking to address through innovative research on climate resilient retrofits. This research aims to understand how to adapt our built environment to withstand natural hazard events.

Why do we need resilient buildings and homes?

Climate change is leading to unprecedented pressure on homeowners and building owners to conduct more frequent or unanticipated repairs, maintenance, and climate resilient upgrades, as well as other changes to their finances, such as increasing insurance, fuel, and utility costs. Several Canadian jurisdictions will be facing concurrent risks related to climate change, such as heat waves and flooding, that will need to be either immediately or incrementally addressed. 
 
Climate change is costing Canadians billions annually

In July and August alone, extreme weather events resulted in $7 billion in insured losses—making 2024 the costliest year in history (Insurance Bureau of Canada, 2024).


Most buildings were not designed for today's climate

Much of Canada's building stock was designed to meet the codes and standards of historical baselines, and are incompatible with today's climate (IISD, 2021).


Disaster losses increased by 1250% from 1970-2019

Extreme weather events in Canada amounted to a total of $18 billion in insured losses from 2010 to 2019 (Canadian Institute for Climate Choices, 2020)


Why retrofit buildings for climate adaptation?

Climate change is causing more frequent and more intense weather and hazard events such as flooding, wildfires and heatwaves, resulting in increased economic, social, and environmental impacts on Canadians. This has put pressure on property owners to consider implementing adaptation measures or face the risk of damages to their homes, and the ensuing need for repairs, upgrades, or relocation. Buildings that were once safe may now be vulnerable to multiple hazards occurring in the same region. Adapting existing structures to withstand the new challenges posed by a changing climate requires innovative solutions that go beyond conventional building codes and standards.

According to the Canadian Climate Institute (2022), spending $1 on proactive adaptation measures now will produce $13-15 in accrued economic benefits related to avoiding future losses and damages.
 

The need for research on climate resilient retrofits

Resilient retrofit research is essential for creating adaptive, cost-effective, and sustainable solutions to protect buildings from the evolving risks of climate changeIt equips homeowners, contractors, and policymakers with the knowledge to tackle multiple hazards simultaneously, reducing long-term risk and enhancing community resilience.


Without robust research, retrofitting efforts may be short-term or inadequate, leaving buildings vulnerable to future, more extreme conditions. Research on resilient retrofits ensures that buildings are adapted not only for current conditions but also for future climate impacts, creating long-term protection for homeowners and communities. As climate change drives the need for building upgrades, resilient retrofits can also be aligned with goals for energy efficiency and sustainability, reducing carbon footprints while enhancing protection.


Our research hopes to provide data and guidance on synergistic retrofits that enhance both resilience and energy efficiency, contributing to broader climate action goals. This research is expected to inform the development of updated building codes, design guidelines, and policies to ensure that new and existing buildings are designed to withstand future climate impacts. It offers data to governments and local authorities to design policies that incentivize resilient retrofits, making communities safer and more prepared for climate change impacts.

Addressing the complexity of multi-hazard risks

Most retrofitting strategies are designed for a single hazard, such as flood protection or fireproofing. However, many areas now face multiple hazards simultaneously. This introduces complexities. For instance, a retrofit that protects against flooding might not work for wildfire defence, or one that reduces extreme heat risks may increase risk for wildfire ignition. 

As such, research that helps to develop multi-hazard solutions that balances and explores these risks can ensure that interventions are effective across different climate threats.

Once we know what makes buildings climate resilient, we can invest in retrofits together with grey and natural infrastructure to reduce disaster risks and impacts on people. And, over the longer term, climate-resilient retrofits will save property owners, insurers, and governments money, and will create added benefits like improved health and reduced carbon pollution.

Climate Resilient Retrofits is a project of Partners for Action (P4A), a research initiative in the Faculty of Environment at the University of Waterloo, with founding funding from the Co-operators Group Ltd. and Farm Mutual Re. Climate Resilient Retrofits has been generously supported by our partners and funders at Halifax Regional Municipality, the National Research Council of Canada, and the Clean Foundation.
