Analysis conducted by the U.S. Department of Energy (DOE) has shown that window attachments have the potential to save significant energy in residential and commercial buildings. In 2014, AERC was formed – with partial funding from the DOE – to provide accurate and credible information about the energy performance of window attachments to help homeowners, architects and builders make informed purchasing decisions.

AERC is comprised of a diverse group of window attachment manufacturers, component manufacturers, public interest organizations and utility companies who work together to deliver the AERC Energy Improvement program in an effort to make buildings everywhere more comfortable and energy efficient.

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.

The AERC Energy Improvement Program Launches in Three Main Phases

The AERC Energy Improvement program is rolling out rated and certified products in three phases; these phases ensure that all products included in the program are rated accurately and fairly. While we are currently anticipating the rollout of Phase 2 & 3 products, all products from Phase 1 are now available and accessible in the Certified Product Search. The directory is continually updated as products are cer0fied.
