CaGBC report recommends nationwide retrofit strategy with potential to cut 51 per cent of emissions from large buildings



Every Canadian stands to benefit from recommendations which could reduce 21 million tonnes of carbon by 2030, help the government achieve its climate change goals, and grow the economy

OTTAWA and VANCOUVER, Sept. 20, 2017 /CNW/ - A new report released today by the Canada Green Building Council (CaGBC) delivers a detailed roadmap for reducing greenhouse gas emissions from large buildings like office towers, recreation centres, hospitals, arenas and schools across the country. CaGBC's A Roadmap for Retrofits in Canada demonstrates the critical role that existing buildings play in realizing Canada's low carbon future. The report provides recommendations to retrofit large buildings that will contribute to achieving a reduction in GHG emissions of at least 30 per cent (or 12.5 million tonnes1) by 2030, with the potential to reach 51 per cent or 21.2 million tonnes. The Roadmap provides government and industry with a targeted plan to yield the greatest carbon savings from buildings and grow Canada's clean economy.

Developed by WSP for CaGBC, this report advances recommendations made in CaGBC's 2016 Building Solutions to Climate Change research by analyzing how the type, size and age of large buildings, along with energy sources and the carbon intensity of regional electrical grids in Canada, can affect energy efficiency and carbon emissions. The report identifies the buildings with the largest carbon reduction potential and recommends provincially-specific retrofit pathways that include a combination of recommissioningi, deep retrofitsii, renewable energyiii, and fuel switching actionsiv.

Among its key findings, the Roadmap concludes that:

"This report makes it very clear that targeted strategic investments in existing buildings represent a massive opportunity for significant carbon reductions across the country," says Thomas Mueller, President and CEO of CaGBC. "We are showing how each region can contribute to meeting Canada's climate change goals through a targeted approach to building retrofit and clean energy. Governments at all levels are encouraged to develop progressive policies and programs to guide investment and support for establishing a robust retrofit economy in Canada."

The report provides the following policy recommendations for the Federal Government:  include a GHG metric in Canada's future retrofit building code; develop regional retrofit roadmaps; prioritize investments in scalable retrofit projects; and supporting mandatory energy benchmarking.

A Roadmap for Retrofits in Canada will be followed by a third CaGBC report, to be published in Spring 2018, which will provide policy options that would overcome barriers that hinder the implementation of retrofit projects and identify the financing mechanisms necessary to stimulate the retrofit economy.

This report was made possible through the generous support of the Real Estate Foundation of British Columbia.

______________________________
1 Net emissions reductions in 2030 are influenced by changes in population and the carbon intensity of the electrical grids (5.6 million tonne reduction) as well as the proposed CaGBC emissions reduction activities (6.6 million tonnes).

i Recommissioning: optimizing the performance and operation of an existing building's system. Following investigation, the measures implemented can include equipment maintenance, adjustments to controls, and minor equipment retrofits. This includes things like upgrading lighting, improving indoor air quality and replacing boilers.

ii Deep retrofits: involves major system and equipment replacement or upgrade. Typically pursued during building renewal events such as envelope and major equipment replacement, new ownership or occupancy, and green building certification. It can include HVAC changes, window replacement, and other envelope and system upgrades.

iii Renewable energy: while many forms of on-site renewable energy exist, including solar thermal, biomass, wind and micro-hydro, solar photovoltaic (PV) electricity generation is most commonly used in existing buildings.

iv Fuel switching actions: switching natural gas and other carbon-intensive heating furnaces, boilers and distributed equipment to low carbon sources like high-efficiency electricity-based systems such as heat pumps.
