Independent Verification Program

As a Partner in the ENERGY STAR program, you have made a business choice to be part of a brand that communicates the message about the energy efficiency of windows, doors, and skylights to consumers. The National Fenestration Rating Council (NFRC) is the leading expert in the certification and testing for windows, doors, and skylights, and is recognized by the EPA as a Certification Body (CB) for the ENERGY STAR program.

To ensure that ENERGY STAR products continue to perform in the marketplace as originally designed and certified, ENERGY STAR requires that all products bearing the logo be made available for independent verification testing. Therefore, NFRC has implemented an Independent Verification Program (IVP) to verify the performance ratings of ENERGY STAR qualified products. In order to meet the requirements as a CB, each Partner must fill out and submit an application form.

Step 1

Apply either online or by downloading the application form and submitting it via email to ivp@www.nfrc.org or by fax (301-220-3129; Attn: IVP Enrollment). Be sure to review NFRC 713 in our program documents for information about the IVP before submitting an application.

Step 2

Complete the enrollment process by accessing the online tool to designate the ENERGY STAR product lines.

You can also download the ENERGY STAR Product Line Identification Manual for instructions on using the tool.
