America’s existing housing needs help. Many of the 130 million homes in this country were constructed before modern energy and building codes were established. These homes often suffer from performance problems ranging from inflated energy consumption to poor thermal comfort to indoor air quality issues.

The Building Performance Institute, Inc. (BPI) is a national standards development and credentialing organization for residential energy efficiency retrofit work. BPI offers professional certification examinations on the assessment and upgrade of residential buildings – both single-family and multifamily. We also provide accreditation to contracting companies committed to whole house home performance, and quality assurance programs that ensure this work adheres to BPI’s nationwide technical standards. 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.

Through a separate division, BPI maintains relations with a network of over 300 test centers that provide BPI written and field exams in their market.

The result? Sustainable, green-collar jobs in local communities that improve the comfort, health, safety, durability and energy efficiency of America’s existing houses.
