The United States Department of Energy (DOE) estimates that heat gain and loss through your house’s windows account for up to 30% of your home heating and cooling energy usage. Poorly insulated windows also force your HVAC system to cycle longer, and the additional wear and tear can shorten the lifespan of your unit. Here are some ways to lower your monthly energy bills by minimizing heat loss and gain through your windows.
Single-Pane Versus Double-Pane Windows
All newly constructed homes now include double-paned windows, but they weren’t common in houses until the 1970s. Single-paned windows aren’t nearly as effective at preventing heat transfer as double-paned windows, so it’s always a smart investment to upgrade your windows. Double-paned windows also include dense gases such as krypton or argon between the panes for an additional level of insulation.
Window Energy Efficiency Ratings
If you’re in the market for new windows, be sure to review their features carefully. Manufacturers measure a window’s energy efficiency rating in terms of its U-value or R-value. A lower U-value means that it allows less heat transfer, while a higher R-value means that it offers increased insulating ability. Be sure to also look for the window’s solar heat gain coefficient (SHGC). SHGC measures the amount of heat transfer generated by sunlight, which is always important to know in Arizona’s arid desert climate.
