What documentation does a commercial energy audit produce?

A commercial energy audit produces a facility-specific energy baseline model, a ranked list of energy conservation measures with savings, costs, and payback for each, an incentive eligibility summary, and — at ASHRAE Level 2 — the documentation required for NRCan and IESO saveONenergy program applications.

Clear answer, explained.

The primary deliverable is the audit report — a formal document that establishes the facility's verified energy baseline, presents each identified conservation measure with quantified savings and implementation costs, and ranks them by financial return. The baseline model is built from actual utility interval data, not industry benchmarks.

The incentive eligibility summary identifies which programs the facility qualifies for based on the audit scope and identified measures. For Ontario facilities, this typically covers IESO saveONenergy Retrofit Incentive pathways for LED, HVAC, and controls measures. NRCan program eligibility is identified for measures qualifying under federal programs.

For facilities subject to Ontario's Building Energy Performance Standards (BEPS), the audit report provides the energy use baseline documentation that BEPS compliance requires. This makes the audit report a multi-purpose document — capital planning tool, incentive application foundation, and compliance record — rather than a one-time deliverable.


Key points

What this means in practice.

  • The primary deliverable is the audit report — a formal document with baseline, ECM list, and incentive eligibility
  • The energy baseline model is built from actual utility interval data, not industry benchmarks
  • Each ECM is presented with estimated annual savings, implementation cost, and payback period
  • The incentive eligibility summary identifies qualifying NRCan and IESO saveONenergy programs
  • ASHRAE Level 2 reports meet the documentation standard required by most incentive programs
  • The audit report serves as BEPS baseline documentation for Ontario facilities subject to compliance

When this applies

Best-fit environments.

  • You are applying for NRCan or IESO saveONenergy funding and need to know what documentation the audit produces
  • Your facility is subject to Ontario BEPS compliance and you need a verified energy baseline on record
  • You are preparing a capital plan and need the ECM list in a format suitable for board presentation
  • You are managing multiple facilities and need consistent documentation for portfolio-level energy reporting
