The Home Energy Professional (HEP) Energy Auditor certification is offered by BPI, and is supported by the U.S. Department of Energy (DOE) and its National Renewable Energy Laboratory (NREL).

The HEP Energy Auditor certification demonstrates advanced competency through rigorous online and field exams, and work experience prerequisites.

Once certified, you will be able to evaluate the energy efficiency, health, and safety of a home. You will gain in-depth knowledge of how to use diagnostic equipment and modeling software to identify areas for energy savings, produce an audit report, and develop a prioritized scope of work for your customer.

Bonus: Getting the Energy Auditor certification automatically earns you the BPI Building Analyst (BA) certification.
