About the Attachments Energy Rating Council

Analysis conducted by the U.S. Department of Energy (DOE) has shown that window attachments (shades, shutters, storm windows, etc.) have the potential to save significant energy in residential and commercial buildings. The Window Coverings Manufacturers Association (WCMA) was awarded DOE funding to help capture these potential energy savings through the creation of a comprehensive rating, labeling, and certification program for window attachments, which is administered by the newly formed Attachments Energy Rating Council (AERC).

The AERC is an independent, public interest, non-profit organization whose mission is to provide consumers with credible, relevant, and comparable information about window attachments and their performance. AERC serves the public interest by providing accurate and credible information about the energy performance of window attachments, which will help consumers, including homeowners, architects, and builders, make informed decisions about window attachment products.

The AERC is comprised of a diverse group of window attachment manufacturers, component manufacturers, public interest organizations, and utilities who are working together to deliver a successful energy rating program for the window attachment industry.


To provide accurate and credible information about the energy performance of window attachment products, as well as to rate, label and certify the energy performance.


AERC’s goal is to provide consumers and decision makers with credible, relevant, and comparable information about window attachments and their performances.


The AERC Rating and Certification Process

AERC’s Energy Improvement rating and certification program, developed with the support of the U.S. Department of Energy (DOE), has been designed to offer independent and accurate information about the energy performance of window attachment products.

Together, our many program stakeholders work to ensure that the information on the AERC Energy Improvement label is accurate, reliable and consistent. Each product that features the AERC Energy Improvement label has been measured according to stringent standards and have been reviewed and certified by AERC. How to read the label.
