We are the nation’s premier standards development organization for residential energy efficiency retrofit and weatherization work. We bring together leading building science experts from across North America to develop our standards using a consensus-based methodology.

In cooperation with these industry stakeholders – including contractors, product manufacturers, building scientists, public program professionals and educators – we have established nationally recognized technical standards in performance contracting for both single-family homes and multi-unit residential structures.

Taking a holistic view, we ensure that all styles and ages of dwelling are included, and all climate zones are covered.

BPI standards or equivalent are cited by the Home Performance with ENERGY STAR^® program from the Department of Energy (DOE) and the Environmental Protection Agency (EPA), as well as several state Weatherization Assistance Programs. We are currently in the process of becoming accredited by the American National Standards Institute (ANSI).
