How to use this guide
Start broad. Verify the exact scope.
An energy audit should produce more than a list of ideas. The useful deliverable explains current conditions, estimated savings, assumptions, costs, priorities, and how recommended work connects to the owner’s operational or compliance goals.
The directory records public audit claims, not audit quality. Confirm the audit level, systems included, on-site work, professional oversight, and intended use of the final report before hiring.
Before hiring
Questions worth asking every finalist.
- What audit standard or level will be used, and why is it appropriate for this building?
- Which systems, utility records, and operating conditions are included or excluded?
- Will recommendations include cost, savings, assumptions, incentives, and implementation sequencing?
- Who signs the report, and what licenses or certifications apply to the work?
