How Do Products Get the ENERGY STAR® Label?

If you’re looking for a product that gives you tremendous energy efficiency while being environmentally friendly, you’re looking for a product with the ENERGY STAR® label on it. The label was established to reduce greenhouse gas emissions and other emissions, and to make it easy for consumers to distinguish and purchase energy-efficient products that are durable and certain to perform.

In this blog, your replacement window contractor, Renewal by Andersen® of San Francisco explains how products get the ENERGY STAR label.


Products can get the ENERGY STAR label by meeting energy efficiency requirements set by the Environmental Protection Agency (EPA). These are the standards that they have to meet:

  • The products must contribute significant amounts of energy savings across the country.

  • Energy efficiency should be broadly available and not tied to proprietary technologies only offered by a specific manufacturer.

  • A certified product must address the needs or the pain points demanded by the consumers, aside from increased energy efficiency. For instance, windows should provide a certain amount of daylighting while increasing the home’s energy efficiency.

  • If the product is more expensive than a regular, less-efficient product, the consumer must be able to recuperate their expenses through increased utility bill savings within a reasonable period.


Much like other certified products, ENERGY STAR windows do not have to possess specific technologies to be certified. However, windows are independently tested, certified and verified by the National Fenestration Rating Council® (NFRC). Once these windows pass the NFRC ratings, they also have to meet the energy efficiency requirements set by the EPA.

Qualified windows feature high-quality, low-maintenance frame materials that are highly sought after by consumers. They also have multiple panes of glass with a gap filled with air or gas like argon in the middle. This makes them more energy-efficient and damage-resistant than other windows. Not to mention, they also grant you a peaceful environment since they block out a significant amount of outdoor noise.
