Energy & Efficiency

NFRC is a non-profit organization that administers the only uniform, independent rating and labeling system for the energy performance of windows, doors, skylights, and attachment products. Our goal is to provide fair, accurate, and reliable energy performance ratings so that:

• Architects, builders, code officials, contractors, homeowners, and others can compare different products and make informed product choices.

• Building officials, state government employees, and others involved in code development and enforcement can determine if products meet local codes.

• Government- and utility-run energy efficiency programs can establish performance requirements and standards.

• Manufacturers have a fair and level playing field to compare products and an accurate method of showing the energy benefits of new designs or technology.


AAMA Mission
Since 1936, the American Architectural Manufacturers Association has stood as a strong advocate for manufacturers and professionals in the fenestration industry and dedicated to the promotion of quality window, door, curtain wall, storefront and skylight products. And today, as the leading trade association representing both the residential and commercial sectors and all framing materials, our mission remains strong. Building on a solid foundation of achievement in these areas, we continue to:

• Lead efforts to address the technical and marketing needs of fenestration product manufacturers, suppliers and test labs
• Work to improve product, material and component performance standards for the fenestration industry
• Address regulatory issues that affect our membership
