Hunter Douglas Earns AERC Energy Rating for Window Shades

Hunter Douglas earned an energy performance rating for window coverings from the Attachments Energy Rating Council and the U.S. Department of Energy on their lines of cellular shades and cellular roller shades.

The addition of these new products follows the inaugural AERC rating earlier this year, which recognized storm windows made by Larson Manufacturing.     

“The expansion of the AERC initiative significantly increases consumers’ ability to upgrade window performance by attaching energy-saving shades to their existing windows,” says Ralph Vasami, executive director of the AERC. “When people buy products with the AERC Energy Improvement label, they are helping improve efficiency while also making them more comfortable, private, and stylish.”    

Hunter Douglas is the first company to rate interior window covering products with AERC.    

AERC provides an unbiased, third-party certification of the energy-saving potential of a window attachment product that uses a sophisticated process of material testing and window modeling to gauge the degree to which a window attachment – such as a shade, blind, or storm window – will improve the performance of that window in reducing heating and cooling usage. Products certified by the AERC have two ratings: one for cool climate, which indicates potential energy savings for home heating versus unprotected windows, and another for warm climate, which does the same for air conditioning.
