NFRC Standardizing Energy Performance Reporting for Windows

NFRC labels now include data on visible light transmittance and solar transmittance.

The National Fenestration Rating Council (NFRC) is taking some significant steps forward in its efforts to standardize

energy performance reporting for windows. Most recently, the Council has determined that, as of January 2000, participating manufacturers will be required to certify solar heat gain coefficient and visible light transmittance for all products submitted for certification. Until now only U-value information has been required. Earlier in the year the NFRC updated its comprehensive

Certified Products Directory and approved a procedure for rating and certifying the performance of site-built products. This last change allows the rating system to include many site-glazed systems used in commercial buildings. The NFRC can be reached at 301/589-6372, or on the Web at

www.nfrc.org.
