NFRC administers several 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 third-party licensed Independent Certification and Inspection Agencies (IAs) operate; the Laboratory Accreditation Program (LAP), which establishes rules and regulations for assuring that test and simulation labs are providing uniform ratings; the FenStar^® Certification Program, which involves manufacturers involved in the ENERGY STAR^® Program; the Component Modeling Approach (CMA) PCP, which establishes the rules for those involved in the commercial label certificate program; the Calculation Entity Approval Program (CEAP), which provides the rules for those involved in the CMA PCP as ACEs; and more.
