Who Can Become a Member?

The AERC is made up of a diverse group of engaged organizations and individuals working together to create a successful energy rating program to help consumers make informed decisions. Organizations or individuals with experience in the window attachments industry and/or energy efficiency are encouraged to join AERC to help drive its development and ensure its success. AERC values a diverse membership that balances industry and public interest participation to help consumers make more energy-efficient choices. AERC members benefit from reduced certification program participation and listing fees.

AERC has four membership categories:


Manufacturer Membership is open to companies that manufacture components, materials, and finished fenestration attachment products. The manufacturer level is based on the company’s prior year’s revenue from North American business related to window attachment products. If a manufacturer owns a subsidiary company or multiple brands, then the subsidiary and/or brands may be covered under the parent manufacturer’s membership, and the organization receives only one vote. A manufacturer that owns a subsidiary company with its own manufacturing location(s) may elect to obtain separate membership for the subsidiary company and therefore a separate vote.

Annual Dues: (based upon annual sales)

Category 1 (< $2 Million Sales) $1,000.
