What is the best way to tell if a window is energy-efficient? Look for the ENERGY STAR® label on products. This badge is only given to windows that have met the government-run agency’s high-performance standards. The ENERGY STAR symbol also guides consumers in identifying and purchasing energy-efficient products that allow them to save on energy bills without sacrificing performance and comfort.
But how exactly do products like replacement windows earn an ENERGY STAR certification?
About the ENERGY STAR® Label
ENERGY STAR has become the standard and symbol for energy efficiency. It was created with the goal of reducing greenhouse gas emissions and other pollutants, which are often produced by inefficient energy use. The ENERGY STAR mark also assists consumers in selecting and purchasing energy-efficient items that help them save money on their utility bills while maintaining performance and comfort.
How Do Windows Earn this Label?
ENERGY STAR-certified windows prioritize energy efficiency. These windows are manufactured with the following features to maximize performance and energy savings:
- Double- or triple-glazing with a sealed insulating glass unit
- Low-emissivity (Low-e) glass
- Inert gas (argon or krypton) in the sealed unit
- Low-conductivity or “warm edge” spacer bars
- Insulated frames, sashes and door cores
- Strong air tightness
Energy-efficient replacement windows make homes more comfortable in cold weather and hot temperatures alike, saving you money as a homeowner and help the planet by slowing greenhouse gas emissions. Additionally ENERGY STAR windows increase comfort, reduce noise levels and filter more ultraviolet (UV) rays than traditional windows.
Who Tests All of These Windows?
The National Fenestration Rating Council® (NFRC) operates a program that tests and certifies windows, doors and skylights for their energy performance. The NFRC certification label is on all ENERGY STAR window and door products.
The ENERGY STAR qualification primarily takes into account the U-factor and solar heat gain coefficient (SHGC) numbers.
