BPI Standards

BPI is a national standards development organization for residential energy efficiency and weatherization retrofit work. As an independent, not-for-profit organization, we bring together leading building science experts from across North America to develop our standards using a consensus-based methodology. Taking a holistic view, we ensure that all styles and ages of dwelling are included, and all climate zones covered.

BPI is accredited by the American National Standards Institute (ANSI) as an approved developer of American National Standards. Through BPI’s Standards Technical Committee and its working groups and dozens of committed industry participants, the BPI Standards program maintains an unmatched reputation as the home performance industry’s leading standards body. BPI functions as a vital connection between companies, contractors and training organizations to ensure the entire home performance and weatherization workforce is following the same strict protocols.

Individuals that have been trained, tested and certified to BPI’s nationally recognized standards use the house-as-a-system approach to improving the performance of existing homes – an approach proven to reduce home owner annual utility bills by as much as 20 percent or more. That's why BPI standards are cited by the Home Performance with ENERGY STAR® program from the U.S. Department of Energy (DOE) and Environmental Protection Agency (EPA), as well as several state Weatherization Assistance Programs.
