Building Energy & Water Reporting (Benchmarking)
Large-building energy disclosure is law in a growing list of Canadian jurisdictions: Ontario’s Energy and Water Reporting and Benchmarking (EWRB) regulation requires commercial, industrial and multi-residential buildings above size thresholds to report annual energy and water use through ENERGY STAR Portfolio Manager, and municipal programs elsewhere are following. The mechanics are fiddly — utility data aggregation, property attributes, verification requirements — and late or wrong filings are the compliance failure of busy Julys.
Who must report
Ontario’s EWRB phases by size, reaching commercial/multi-residential buildings of 50,000 square feet and up, with annual July 1 deadlines. Requirements include certain-year data verification by a qualified professional. Other jurisdictions — federally influenced programs, municipal climate bylaws — are converging on the same Portfolio Manager infrastructure, which makes one clean setup serve multiple regimes.
What we handle
Portfolio Manager account and property setup with correct attributes (gross floor area definitions trip most self-filers), utility data collection including whole-building aggregate requests to utilities for multi-tenant buildings, meter mapping, submission through the provincial portal, and verification cycles when your year requires them.
Beyond the filing
Benchmarking’s real product is the comparison: your building against its peers, year over year. Scores drive tenant questions, lender ESG reporting and retrofit prioritization — owners who file-and-forget leave the useful half of the exercise unclaimed.
How the process works
- Tell us the building size, type and province/municipality.
- We confirm whether and when reporting obligations apply.
- Portfolio Manager setup and utility data aggregation are completed.
- The filing is submitted before deadline; verification arranged when required.
- Annual recurrence is automatic; scores are reported to you with peer context.

Frequently asked questions
Does EWRB apply to my building?
In Ontario: commercial, multi-residential and some industrial buildings of 50,000 sq ft and larger. Measurement uses specific gross-floor-area rules — buildings near the threshold should verify rather than assume.
What happens if we miss the deadline?
Provincial follow-up and potential enforcement; practically, scrambled filings produce bad data that haunts later years. Catch-up filings are straightforward — start now rather than skip a year.
How do we get tenant utility data?
Ontario utilities must provide whole-building aggregate data on request for EWRB purposes — the request process is exactly the fiddly part we run for owners.
Is our reported data public?
Ontario publishes building-level results after a phase-in. Assume disclosure — which is an argument for making the numbers better, not for avoiding the filing.
