A Clear View of Window Energy Savings

A leading energy efficiency group recently highlighted research from Lawrence Berkeley National Lab (Berkeley Lab) as part of a blog post about new in-store labels for window coverings. The labels for attachments such as blinds and shades are informed by a product rating and certification program developed via extensive modeling and research at Berkeley Lab. The text from the American Council for an Energy-Efficient Economy (ACEEE) follows:

Based on a product rating and certification program developed for AERC by Lawrence Berkeley National Lab, the label lets consumers compare expected energy savings for window attachments in warm and cool climates. Participating manufacturers have started to label products they offer for retail sale; labeling information is also available on the AERC website and from specialty dealers and interior designers...
