Who performs a commercial energy audit in Ontario?

Commercial energy audits in Ontario are performed by qualified energy professionals — typically engineers or certified energy managers (CEMs) with experience in commercial and industrial building systems. For NRCan and IESO saveONenergy program applications, the auditor must meet specific credential requirements defined by those programs.

Clear answer, explained.

For incentive-qualifying audits, the auditor's credentials matter as much as the methodology. NRCan's Industrial Energy Management program specifies that the energy professional performing the audit must meet its credential requirements — typically a professional engineer (P.Eng.) or a certified energy manager with relevant C&I facility experience. IESO saveONenergy has similar requirements for approved energy advisors.

The auditor's sector experience is also relevant. A commercial energy audit for a food processing facility involves different systems — refrigeration, process loads, steam — than one for a warehousing operation or office building. Auditors with experience in the specific facility type will identify opportunities that a generalist may not recognise.

For projects that include both efficiency and solar components, the auditor should have the capability to assess both — or work as part of a team that does. Solar feasibility assessment requires electrical engineering competency to evaluate interconnection headroom, service capacity, and system sizing against the post-efficiency consumption profile.


Key points

What this means in practice.

  • Commercial energy audits should be performed by qualified energy professionals — P.Eng. or CEM with C&I experience
  • NRCan and IESO saveONenergy programs specify credential requirements for the auditor
  • Sector experience matters — auditors familiar with your facility type identify opportunities others may miss
  • Food and beverage, manufacturing, and warehousing facilities have distinct system profiles that require relevant expertise
  • Projects combining efficiency and solar require electrical engineering capability for interconnection and solar feasibility assessment
  • Credential verification is a standard part of program application — confirm the auditor's qualifications before engaging

When this applies

Best-fit environments.

  • You are selecting an energy auditor and want to confirm credential requirements for NRCan or saveONenergy applications
  • Your facility is in a specialised sector — food processing, cold storage, manufacturing — and you want an auditor with relevant experience
  • You are planning a combined efficiency and solar program and need an auditor with capability across both
  • You want to understand the difference between a general energy consultant and a qualified energy professional for incentive purposes
