The FenStar® Certification Program is NFRC’s program for ENERGY STAR® product certification. NFRC will be a fully accredited certification body for the ENERGY STAR window, door, and skylight program.

ENERGY STAR partners will need to update their product line information in PESI, update the Schedule II, and sign a new NFRC license agreement. In addition, manufacturers will need to provide copies of the installation instructions provided with ENERGY STAR products, air leakage certification information, and a sample of a products line’s ENERGY STAR and NFRC labels for verification. NFRC will be investigating ways to automate this information if possible (such as getting the air leakage data directly from the CPD) to ease the burden on the manufacturer.

In 2020, ANSI’s National Accreditation Board (ANAB) awarded the accreditation to NFRC after an extensive review process confirmed its FenStar® program meets the ISO/IEC 17065 standard used for certification bodies around the world. NFRC is the only certification organization rating the energy efficiency of windows, doors, and skylights. For more information on this, please click here.

The FenStar Certification Program is a requirement for the U.S. version of ENERGY STAR. It does not affect Canadian products unless those products are sold in the U.S. as part of the U.S. ENERGY STAR program.

No. The ENERGY STAR Partner agreement is still intact and is between the Partner and the EPA. The FenStar Certification Program license agreement does not supersede any of the EPA requirements.
