NFRC administers three programs to ensure that the energy performance ratings found on NFRC Labels are fair, uniform, and credible. These programs include: the Product Certification Program (PCP) which establishes the rules under which a fenestration manufacturer can rate and label products; the Certification Agency Program (CAP) which establishes the rules by which our third party licensed Independent Certification and Inspection Agencies (IAs) operate; and the Laboratory Accreditation Program (LAP) which establishes rules and regulations for assuring that test and simulation labs are providing uniform ratings.
