The Building Performance Institute has been accredited by the American National Standards Institute as a certifying organization.

ANSI’s accreditation is based on the institute’s residential building envelope whole- house air-leakage-control installer certification program. BPI officials said.

“The development and execution of ANSI procedures is a major undertaking, and BPI has committed considerable resources to ensure its success," said David Hepinstall, BPI chairman. "Many organizations develop industry level certifications for technicians within their sector, but achieving accreditation to this international standard means BPI has put in place processes critical to delivering fair exams at every BPI test center across the country."

Larry Zarker, the institute’s CEO, said the certification will help BPI grow.

"This milestone will carry BPI and the contractors it serves well into the future,” he said. “It allows us as an organization to continue to grow and provide home-performance professionals with the support and resources they need to succeed.”
