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.

“I have been associated with Apple Energy for a number of years and with Greg Hall personally over the same time period.  During this time period, I have had the opportunity to work with Greg and Apple Energy in several business areas.  I have always been impressed with the professional nature of his company and especially the individuals who are apart of his Apple Energy team.  I am also very impressed with Greg's ability to attract and hire quality young enthusiastic individuals who support his business development programs, while maintaining an extremely capable and experienced technical training staff. These attributes of Apple Energy along with Greg's ability to set strategic objectives create a very dynamic business entity.”
