What’s the Difference Between ENERGY STAR® and the NFRC?

New windows can transform your home from the inside out. They can make your living space easier to heat and cool, helping reduce your energy costs. That’s why you should consider energy efficiency ratings and choosing replacement windows. 

You might come across ENERGY STAR® and National Fenestration Rating Council (NFRC) ratings in your search for energy-efficient products. Read on to learn the difference between them.  

The ENERGY STAR® Certification

Whether planning a window replacement or siding installation project, it pays to invest in energy-saving materials. When looking for new windows, look for products certified by ENERGY STAR. It is a widely recognized program initiated by the U.S. Environmental Protection Agency (EPA) to help individuals choose products that reduce their energy consumption and carbon footprint. Goods bearing the ENERGY STARhave been independently certified to meet stringent energy efficiency requirements set by the EPA.

ENERGY STAR evaluates windows based on their ability to lower energy bills. According to its criteria, by replacing old single-pane windows with those that are ENERGY STAR certified, homeowners can save up to 13% on their energy bills. Moreover, this program categorizes windows based on climate zones, helping consumers purchase products suitable for their location. 

The NFRC Label

The NFRC is a non-profit organization that provides a standardized method to report the energy performance of windows, doors and skylights. Unlike ENERGY STAR’s categorical certification, the NFRC label offers specific performance ratings to help consumers compare products.

This label includes ratings for U-factor, solar heat gain coefficient (SHGC), visible transmittance, air leakage and condensation resistance. These ratings will help you assess a window’s ability to insulate and transmit solar radiation. While the ENERGY STAR certification tells you that a product is generally efficient, the NFRC label specifies how it’s efficient.
