Decarbonizing Canada’s Large Buildings is a new report commissioned by the Canadian Green Building Council (CaGBC ) and executed by two consultancies: RDH Building Science and Dunsky Energy + Climate Advisors. Those researchers used “whole-building energy modelling” to evaluate deep carbon retrofit opportunities across 50 different building archetypes, reflecting a range of building types (office, multi-unit residential, and primary school), sizes (low-rise and midrise), ages (1970s and 1990s) and regions (Halifax, Montreal, Toronto, Edmonton, and Vancouver). The researchers developed baselines and assessed business-as-usual upgrades, and also identified and assessed the performance outcomes of deep carbon retrofits. Some highlights from the report: full decarbonization by 2050 is technically viable for all the building archetypes, though some are more financially appealing than others – and office buildings are the “low-hanging fruit.” The key technical solutions identified are to 1. Reduce/replace fossil fuel use for space heating, mainly through electrification, 2. Implement energy demand-reduction measures and, 3. Incorporate and/or install on-site renewable energy systems. The report emphasizes the urgency of action, calling for governments to introduce mandatory building performance requirements, mandatory energy performance benchmarking and disclosure programs, and improved incentive programs, such as innovative loan programs, such as property-assessed clean energy (PACE) and on-bill financing (OBF), among programs.
In calling on policy-makers to ramp up education, low-carbon skills training, and industry capacity, the CaGBC report recommends 1. collaborative training programs, leveraging the existing training opportunities offered by industry associations; 2. Incorporating deep carbon retrofit training into continuing education requirements for architects and engineers. 3. Increased government investment in building-related retrofit training programs offered by many unions and community colleges; 4. Improving industry buy-in by collaborating with manufacturers.
