It's our 20th anniversary. Take a trip through history with us.
  • Welcome!

    In 1993 a group of building tradesmen and weatherization program professionals had a vision for independent, third party verification of worker skills in the weatherization industry. From this vision the Building Performance Institute took its first steps.

    BPI has played a pivotal role in shaping the nascent home performance industry by developing technical standards, credentials and quality assurance relied upon by thousands of contractors. Today BPI certified professionals hold over 35,000 active certifications across all 50 states and four foreign countries. More than 130 energy efficiency programs specify BPI credentials to ensure quality. Over the next 20 years BPI will continue to raise the bar, helping contractors provide safe, high quality and cost-effective home performance solutions to homeowners around the world.

  • 1993

    During a DOE and New York State Weatherization Program sponsored 3-day retreat in New York City, a group of 35 building performance professionals develop a set of principles to serve as the structure and philosophy of a building performance industry. It was from this retreat that the Building Performance Institute took its first steps, as it was decided that certifications, not just training, were critical to ensuring the quality of work performed.

    BPI is established as a program under New York State’s NYSTAR program with a mandate to create a Building Performance Field Manual.

  • 1994

    “We drew a line in the sand between training and certifications.”
    – David Hepinstall
    Association for Energy Affordability (AEA)
    and BPI Chairman of the Board


    The founders specify that BPI’s mission is to develop certifications to verify the knowledge, skills and abilities of workers, and not conduct training directly. From this directive, the concept of joint written and practical exams was born – and that training would be carried out by a third party.

  • 1995

    BPI acquires a facility in Glens Falls, New York to accommodate office space and a “testing house” configured to adequately test candidates on their ability to apply their skills in a real life setting.

    "By setting standards and credentialing contractors, BPI played a pivotal role in shaping the home performance industry by ensuring work is conducted in a safe manner, and based on sound building science.”
