Why Energy Efficiency Matters
Energy efficiency can mean doing different things around the house to prevent heat loss or limit the amount of heat that enters a home. Evaluating your windows and patio doors can help make your home more energy efficient.
Energy efficiency means using less energy to perform the same function. An easy example to think about is energy efficient lightbulbs. An energy efficient lightbulb will still light a room, but use less energy to do so. Energy efficiency, however, is not the same as energy conservation, which means reducing a good or service to save energy. Using the lightbulb example, turning off a light is energy conservation.
Energy efficient windows are windows designed to prevent hot air from leaving your home or prevent cool air from escaping your home. Windows use glass coatings to do so and some coatings work best in different climates.
An easy way to find energy efficient windows is to look for windows with the ENERGY STAR® logo. Windows with the ENERGY STAR logo have met ENERGY STAR standards for energy efficiency. A National Fenestration Rating Council sticker can further explain the energy efficiency of a window. A NFRC label helps you compare energy-efficient products by examining things like U-factor, Solar Heat Gain Coefficient (SHGC), Visible Transmittance (VT), and Air Leakage.
The NFRC estimates the average American household spends $1,500-$2,500 annually on energy bills with 45% of that going toward heating and cooling costs.
The U.S. Department of Energy estimates a homeowner can save between $101-$583 a year on average, if they’re replacing single pane windows with ENERGY STAR windows. For double pane windows, those savings range between $27-$197.*
*Ranges are based on the average savings among homes in modeled cities. Actual savings will vary based on local climate conditions, utility rates, and individual home characteristics.
Tax credits for energy efficient windows can vary between legislative sessions. Energystar.gov has the most up-to-date information on energy efficient tax credits.
Determining when it’s time to replace your windows can depend on the specific issue you’re facing. If you’re experiencing a broken window or damaged frame, you’ll likely want to take immediate action – but if you’re looking to refresh your home you might take a little more time to decide.find out why
The U.S. Department of Energy estimates that 30% of a home’s heating energy is lost through windows while 76% of sunlight that falls on standard, double pane windows turns into heat during the summer.Ways you can save
