EPA Ensures ENERGY STAR Program Integrity

To maintain consumer trust and oversight of ENERGY STAR certified products, homes, and commercial facilities, the Environmental Protection Agency (EPA) undertakes a range of efforts to protect the ENERGY STAR trademark. Across all aspects of the ENERGY STAR Program, formal partnership agreements clearly outline the terms and conditions for using the ENERGY STAR name and marks as described in the ENERGY STAR brand book.


To earn the ENERGY STAR label for products, manufacturers are required to sign a formal agreement with EPA and products must be third-party certified against strict performance requirements. Third-party certification ensures products are properly tested and reviewed prior to being labeled. It also eliminates the competitive advantage associated with possible cheating and preserves the label’s value in the marketplace.

EPA currently oversees third-party certification and manages certified product lists for more than 80,000 product models, including oversight of more than twenty certification bodies and more than 500 recognized labs. EPA also oversees post-market testing of a subset of all products each year to ensure product performance, as well as periodic audits of product labeling on shelves at major retailers to monitor use of the mark. Learn more about measures related to ENERGY STAR products.

ENERGY STAR Residential New Construction

To earn the ENERGY STAR, a new home or apartment must undergo a rigorous process of third-party inspections and testing to verify that all applicable program requirements are met. For site-built homes and apartments, this verification is performed by an independent home energy rating company, and under the oversight of an EPA-recognized Home Certification Organization (HCO) or a Multifamily Review Organization (MRO), depending on the verification method used. For homes built in a factory environment, a Plant Certifier, operating under the oversight of an EPA-recognized Quality Assurance Provider (QAP) ensures that a manufacturing plant has systems in place to consistently build ENERGY STAR certified homes and performs ongoing quality control testing. To be recognized as a Home Certification Organization, Multifamily Review Organization, or recognized Quality Assurance Provider, an organization must submit an application to EPA demonstrating that it meets the program’s eligibility criteria and can successfully perform the required roles and responsibilities outlined in the application.

ENERGY STAR Commercial Buildings

To earn the ENERGY STAR, buildings achieving a score of 75 or higher using Portfolio Manager must undergo verification by a Licensed Professional (Professional Engineer or Registered Architect). The Licensed Professional must verify that all energy use is accounted for accurately, that the building characteristics have been properly reported (including the square footage of the building), that the building operates in accordance with industry standards for indoor environment criteria. Learn more about building certification.

ENERGY STAR Industrial Plants

To earn the ENERGY STAR, industrial plants achieving an energy performance score of 75 or higher must have a Professional Engineer certify that the information used to calculate the plant‘s 75 or higher energy performance score is correct. In addition, the plant must satisfy EPA environmental compliance criteria screen. Learn more about plant certification.

The program’s emphasis on testing, independent review, and compliance screening bolsters its integrity and ensures that consumers can trust ENERGY STAR certified products, homes, and commercial facilities to deliver the energy savings promised by the label.
