The National Fenestration Rating Council’s (NFRC) board of directors approved four NFRC documents, which are now open for public review according to the American National Standards Institute’s (ANSI) process. The public review and related comment period are scheduled to run through June 19, 2023.
Among the four documents submitted for public review, comment and the full ANSI consensus process are:
- NFRC 100: Procedure for Determining Fenestration Product U-factors;
- NFRC 200: Procedure for Determining Fenestration Product Solar Heat Gain Coefficient and Visible Transmittance at Normal Incidence;
- NFRC 202: Procedure for Determining Translucent Fenestration Product Visible Transmittance at Normal Incidence; and
- NFRC 500: Procedure for Determining Fenestration Product Condensation Index Ratings.
An announcement for public comment appeared in a Standards Action on May 5, 2023, marking the beginning of the open public comment period. With the documents being available electronically, the comment period is 45 days, ending on June 19, 2023.
All changes subject to public review have been balloted and approved by NFRC membership and its board of directors.
Documents up for review with changes from previous versions are shown in underline/strikethrough format, with additional details. Applications for joining a related committee are available on the NFRC Documents in Public Review page.
NFRC’s Standards Committee oversees the review process. This committee is now in need of a new member in the User category, including:
- Consumers and consumer advocacy organizations;
- Utilities and other energy service providers;
- Architects, specifiers and design professionals;
- Builders and other construction contractors; and
- Similar parties with interests in fenestration issues.
