energy efficient windows

Energy efficient windows can help you save money on heating and cooling costs. 

You have heard this all before, and you may be somewhat hesitant to think that new windows could really make that much of a difference to your home’s energy costs. However, consider this fact from the U.S. Department of Energy’s website:

“Heat gain and heat loss through windows are responsible for 25%–30% of residential heating and cooling energy use.” Let that statistic sink in as you consider whether you should buy replacement windows for your home.

How Energy Efficiency Is Measured

The DOE and other government agencies are interested in decreasing the energy usage of Americans. That’s why there are labeling systems designed to help consumers make good choices. Make sure you read the window labels when purchasing replacement windows for your home.

NFRC label

The government sponsors the National Fenestration Rating Council, a nonprofit organization that supports an energy efficiency certification and labeling program for windows, doors, and skylights. It’s worth noting that NFRC labels don’t rate products as good or bad. Instead, the NFRC labels help homeowners compare various brands’ energy performance and energy-saving features. 

  • U-Factor — The U-value measures how a window keeps heat from escaping the room. A low U-factor (between 0.20 and 1.20) means better insulation. 
  • Solar Heat Gain Coefficient — Solar heat gain coefficient measures resistance against increased heat from solar radiation. Low E coatings (or low emissivity coatings) on the glass help give these windows a desirable score between 0 and 1. 
  • Visible Transmittance — Visible transmittance measures how well a window allows natural light into your space. The good news is that low e coatings don’t hinder visible light.
  • Air Leakage — Of course, air leaks can decrease a home’s energy efficiency. 

Energy Star label

Energy Star ratings take into account the data that is collected from the NFRC. An Energy Star label means that the product has met the strict energy efficiency requirements set by the government. You probably have seen the Energy Star logo on various products, including refrigerators, furnaces, or any product you would purchase that could substantially affect your energy bills.

In short, if you are interested in energy savings, look for Energy Star windows. 

An Important Thing to Consider When Buying an Energy Efficient Window

We know your mind is probably spinning with all there is to know about buying energy efficient windows. But unfortunately, we have only scratched the surface. For example, you probably have questions about replacing single pane windows with triple pane windows. You may also want to know if you should select argon or krypton gas to prevent condensation and improve energy efficiency.

While these are important topics that can affect your energy bill, it’s also worth noting the importance of hiring an expert for your window installation project. Your windows will only perform well when installed properly.
