Energy Efficiency Training 

Building Performance Institute (BPI)


BPI is the industry leader in providing professional certifications for the residential energy efficiency workforce.

Obtaining BPI certification enables one to be distinguished as a highly trained and skilled residential retrofit professional and home energy auditor.  BPI is on the frontline of the emerging national home retrofit market and is recognized by the U.S. Department of Energy (DOE) as the benchmark for home performance accreditation.  In fact, many retrofit programs across the country, such as Home Performance with Energy Star, require participating contractors to be certified through BPI or an organization with equivalent standards.[1]

What does this mean for me?

By 2020, there will be an estimated 129 million homes across the nation that would benefit from energy efficiency retrofits.[2] As a result, there is an enormous need for qualified professionals to provide home energy audits and perform retrofits.  BPI gives you the credentials to capitalize on this tremendous opportunity and offers you the expertise to be a part of the movement to advance home performance.

“If you’re looking for certification training to enter the Building Performance Industry, if you’re interested perhaps in gaining a BPI certification, if you’re trying to further your education for whatever reason, I can’t make any stronger recommendation than that you sign up for a course hosted by Apple Energy Group. These guys have got the right stuff. And I think it’ll be well worth your time to stick with your course of study in order to move your career forward. You’ll probably use one of our textbooks in that course and I think that what you’re going to learn is going to be more than you could possibly hope for. Apple Energy Group can do that for you. Good luck in this next career transition.”
