The Building Performance Institute has named three companies to provide quality-assurance services to its contractor network.

The Building Performance Institute has picked Conservation Services Group, Energy and Environmental Training Center of Kansas City, and Everblue Energy Inc. to provide quality-assurance services to its contractor network.

"BPI is proud to announce our partnership with these three organizations that have each been widely recognized for their outstanding delivery of quality assurance services in home performance," said institute Chief Executive Officer Larry Zarker. "With the growth of BPI's accredited contractor network across the nation comes our obligation to provide rigorous third-party QA services the market demands. BPI staff can't be everywhere at once. Thus we are confident that these three firms will provide the quality assurance in their respective regions the industry needs to maintain BPI's standards."
