Clear strategy for energy-efficiency upgrades needed for deep emissions reductions

Governments at all levels in Canada are moving toward requiring new homes and buildings to be constructed to low-carbon, ultra energy-efficient standards by 2030, according to a Pembina Institute study.

But Canada still lacks a comprehensive strategy to achieve the significant reductions in carbon pollution from existing buildings that are necessary to meet our country’s climate targets.

The Pembina Institute and The Atmospheric Fund have released a discussion paper entitled Energy Regulations for Existing Buildings.

The paper identifies key opportunities and challenges for the federal government to consider as it works with the provinces to create and implement such a strategy for existing buildings.

Although supporting measures such as financing, incentives, energy labeling, and voluntary programs are critical tools, the paper points out that an ambitious and clear pathway set through building codes and regulations is essential for deep emissions reductions.

“Significantly reducing carbon pollution is essential to making good on Canada’s climate commitments. We need the federal and provincial governments to work together to set out a clear and ambitious pathway to deep emissions reductions in the existing building stock,” said Karen Tam Wu, director of the Buildings and Urban Solutions Program, Pembina Institute.

The Pan-Canadian Framework on Clean Growth and Climate Change committed to the development of a national model code for existing buildings by 2022.

Provinces, territories, and municipalities could then adopt the model retrofit code as part of their building regulations.

Energy use in buildings accounts for nearly a quarter of Canada’s carbon pollution. Every $1 million invested in energy efficiency generates $3-4 million in economic growth.

Establishing the overall level of carbon reductions needed in Canada’s building sector, and setting targets for reductions from existing buildings are key considerations in the development of retrofit code requirements.

Reducing the energy used by existing buildings through codes will result in reduced operating costs for homeowners due to lower energy or maintenance costs, and economic benefits from retrofit activity and investment in the building stock.

 

“While the federal government has set economy-wide emissions targets, it has yet to define the carbon reductions expected from each sector, including the building sector. Establishing targets for Canada’s existing building stock is needed to guide a comprehensive retrofit strategy for Canada — one that includes the development of stronger building codes and regulations,” said Bryan Purcell, director of policy and programs, The Atmospheric Fund.
