The Various Ways a Product Earns the ENERGY STAR® Label

Replacement windows and entry doors can help your home become energy-efficient and allow you to save up on your utility bills. There are various ways to tell if a product is energy-efficient, one of them is to look for an ENERGY STAR® label. How does a product earn this much-coveted label, though?

The Various Ways a Product Earns the ENERGY STAR® Label

In this post, Renewal by Andersen® of Central Illinois discuss how a product earns the ENERGY STAR label.

Manufactured by ENERGY STAR Partners

Whether it’s a replacement window or a storm door, the first requirement a product must meet to earn the ENERGY STAR label is that it must be manufactured by ENERGY STAR partners. Two of these partners are Renewal by Andersen and ProVia® Door, Inc., both of which supply the best energy-efficient windows and doors on the market.

Independently Tested by the National Fenestration Rating Council

Another requirement a product has to meet before earning the ENERGY STAR label is that it must be tested, certified and verified by the NFRC. The NFRC is a third-party organization that helps consumers compare window, door and skylight performances. They provide performance ratings in five categories: U-Factor, Solar Heat Gain Coefficient (SHGC), Air Leakage (AL), Visible Transmittance (VT) and Condensation Resistance. All of these can affect a product’s energy efficiency.

Meet the Specifications Set by the Environmental Protection Agency

The EPA also has some involvement in how a product becomes ENERGY STAR-certified. They set various specifications based on a set of guiding principles that the product must meet. For instance, before attaining the ENERGY STAR label, a product must contribute significant energy savings nationwide. The product must also deliver features and performance demanded by consumers apart from the increased energy efficiency.

"I would recommend RBA of Central Illinois for QUALITY windows and doors. Compared to our old cheap, thin vinyl windows, Andersen blows them away. You can easily tell by how well the sliding doors fit and close, and how heavy duty they are. We also cannot hear the wind rushing through the house in inclement weather anymore! And the black window frames we went with are amazing to look at. Aaron, Al, Darrell, and Cory all were professional and went all out to finish the job, given the weather they had to deal with. I would definitely recommend. They were also on top of communicating with me given the weather delays, and what I could expect for them coming out. Five stars!"
