America’s Existing Housing Needs Help

Many of the 130 million homes in this country were constructed before energy and building codes were established. These homes often suffer from performance problems ranging from energy consumption to poor thermal comfort to indoor air quality issues.

In response to these issues, the Building Performance Institute, Inc. (BPI) was founded in 1993. BPI has become the nation's premier standards development and credentialing organization for residential energy auditing and upgrade work. BPI is a 501(c)(3) nonprofit organization.

BPI is led by a dedicated Board of Directors and a team of 20+ Client Relations, Marketing, Operations, and Technical staff.


All homes are comfortable, healthy, safe, durable, and energy efficient.


BPI provides quality standards and credentials for evaluating and upgrading the performance of homes.
