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: When you have earned the Energy Auditor certification, BPI will also grant the Building Analyst Professional certification for an administrative fee.

BPI Energy Auditors must recertify every three (3) years.

If you have accumulated and submitted at least twenty-four (24) relevant BPI Continuing Education Units (CEUs) over the course of the time you were certified, you may bypass the online exam when it comes time to recertify. In addition, all candidates must re-take the field exam prior to expiration. Once you are EA recertified, you are automatically agreeing to BPI’s Code of Ethics.

Please refer to the recertification section in the Energy Auditor Certification Scheme Handbook for more information.
