Does Window Film Need Another Rating System?
Is there room for another window film rating system? The U.S. Department of Energy (DOE) thinks so. With a $1.6 million cost-shared grant from the DOE, the Window Covering Manufacturers Association (WCMA) launched the new Attachments Energy Rating Council (AERC).
AERC says it “will design and administer a new energy rating and certification program for the fenestration attachment products,” including applied films.
According to the release, the council will gather key market and technical data to develop credible rating, certification, labeling and performance-verification procedures that will be adopted by the attachments industry. “At present there is no accurate method to assess the performance of individual products or for consumers to distinguish among the relative energy-saving performance of competing window attachment products,” the release reads.
Officials at the National Fenestration Rating Council (NFRC), which has a rating system for window film, are unsure what the AERC’s end goal is regarding film.
Ray McGowan, senior program manager at NFRC, says there’s no need for another rating system for window film. “It’d be a waste of their time. We find it a little puzzling since we already have a rating. We certainly don’t want two ratings out there.”
USGlass contacted the DOE regarding already-existing ratings and received this statement: “The department has developed a strategy to support the rapid deployment and installation of energy-efficient fenestration attachments based on its own analysis and stakeholder feedback ... to make it easier for consumers to understand how these products conserve energy and to help them compare various products and models … It is unclear how the NFRC and AERC ratings for window films will compare to one another. The AERC ratings have not yet been finalized."
