What's different about auditing in Toronto
- Two reporting rules: Ontario Energy and Water Reporting and Benchmarking (EWRB) for buildings of 50,000 sq ft and up, and the City's reporting for 10,000 to 49,999 sq ft, first due July 2, 2027. The audit and the report use the same data, so we do both in one pass. Check which applies.
- Funding for the audit itself: Enbridge Gas pays up to 50% of eligible assessment costs, to $10,000 for commercial buildings and $20,000 for institutions, for customers using 100,000 m³ of gas a year or more, with pre-approval.
- Financing for the upgrades: City of Toronto Energy Retrofit Loans can cover the projects the audit finds; the City asks for an ASHRAE Level 2 or equivalent description of the building.
- A deadline on incentives: current Save on Energy project incentives must be approved by December 31, 2027, before equipment is bought.
