Natural Resources Canadas Office of Energy Efficiency offers the ecoENERGY Retrofit Incentive for Buildings, the commercial/institutional component of the ecoENERGY Retrofit financial incentives for existing homes, buildings and industrial processes. This programme targets owners of small and medium-sized buildings in the commercial and institutional sectors, who often lack the financial and technical resources to make energy improvements. Programme participants could receive CDN 10 per gigajoule (GJ) of estimated energy savings, 25 percent of eligible project costs or CAD 50,000 per project. When applying, participants need to provide a pre-project energy audit of the buildings. As well, participants cannot incur any costs related to the project until they receive a signed Contribution Agreement from the Government of Canada. Since August 2008, the ecoENERGY Retrofit Incentive programme for buildings has been open to projects in larger buildings. Businesses and public institutions with 10,000 to 20,000 square metres of floor space are now eligible to receive incentives to undertake retrofit work aimed at improving their energy performance.
