Starting in October 2023 - Energy Star window changes
The ENERGY STAR program, a joint initiative of the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE), has long been a trusted source for consumers seeking energy-efficient products. In October 2023, the program raised the bar for residential windows with the introduction of Version 7.0 standards. These changes mark a significant step towards greater energy savings and environmental protection.
What's New in ENERGY STAR 7.0?
The most notable change is the increased stringency of energy efficiency requirements. To earn the ENERGY STAR label, windows must now meet higher standards for:
U-Factor: This measures how well a window insulates, with lower numbers indicating better performance. The new standards require lower U-factors, meaning windows must be more effective at preventing heat transfer.
Solar Heat Gain Coefficient (SHGC): This measures how much solar heat enters through a window. The updated standards adjust SHGC requirements to balance the need for solar heat in winter with the desire to minimize it in summer.
Impact on Consumers
These energy star window changes have several important implications for homeowners:
Greater Energy Savings: Homes with ENERGY STAR 7.0 certified windows can expect significant reductions in energy consumption compared to homes with older, less efficient windows. This translates to lower energy bills and a smaller carbon footprint.
Tax Credit Opportunities: Homeowners who install ENERGY STAR 7.0 certified windows may be eligible for federal tax credits, further incentivizing the adoption of energy-efficient home improvements.
