Canadian Real Estate Leaders Call for Public Disclosure of Building Energy & Carbon Data (Ind. Report)
Canada Green Building Council
The Canada Green Building Council (CaGBC) has released the results of its Disclosure Challenge, an initiative designed to champion the importance of energy bench-marking and data transparency in the Canadian commercial real estate market. The results have CaGBC and initiative participants, including QuadReal, Triovest Realty Advisors Inc., Concert Properties Ltd., Colliers International, and the Minto Group calling on federal and provincial governments to implement consistent building data disclosure regulations and requirements.
For Canada to reach its emissions reduction targets and transition to a low-carbon economy over the next decade it is essential that existing buildings achieve significant energy efficiency improvements. One of the barriers to meeting these goals is the current lack of publicly available data on commercial building performance in Canada.
While energy bench-marking regulations are in effect in Ontario, the Challenge marked the first time Canadian real estate owners have voluntarily disclosed their Canada-wide portfolio data. These five participants publicly disclosed available data for over 11 million square meters of space in buildings spread across the country from Victoria to Halifax including offices, warehouses, residential apartment buildings and retail shops.
Insights from the Disclosure Challenge show:
In comparison with Natural Research Canada (NRCan) average site energy use intensity values, overall participant office buildings performed approximately 10 pct better than the average office in Canada, whereas participant multi-residential buildings were about even with the average.
Average energy use intensity for office and multi-residential buildings in the challenge were 286 kWh/m2 and 256 kWh/m2 respectively. As compared to high-performance efficiency standards for new office and multi-residential buildings in Canada coming into force in different jurisdictions (with a standard of 100 kWh/m2). Disclosure Challenge office buildings were approximately 65 pct less efficient and multi-residential buildings were 61 pct less efficient.
GHG Emissions intensity varied across the country and was generally correlated with the electricity supply grid intensity, so office buildings in Alberta were as high as 170 kgCO2e/m2 and apartments in British Columbia were as low as 24 kgCO2e/m2 .
