The National Fenestration Rating Council (NFRC), which establishes objective window, door, and skylight energy performance ratings, has acquired the Efficient Windows Collaborative (EWC) and its proprietary online Window Selection Tool.
As the science behind ENERGY STAR certification for fenestration products, NFRC rates and certifies the energy efficiency of windows, doors, and skylights that make buildings more comfortable and reduce carbon emissions. At the same time, the EWC has been an online resource for consumers to find the high-performance windows specific to their needs. Now, as one well-respected organization becomes a part of another, together NFRC and the EWC will bring a new level of expertise, education, and support to consumers searching for windows for their homes and businesses backed by fair, accurate, and credible ratings.
