As energy efficiency standards continue to change, Energy Star 7.0 is the latest update every homeowner should know about, especially if you’re thinking about replacing your windows in 2026. These new standards raise the bar for how windows are evaluated for energy performance, which can directly affect your home’s comfort, energy bills, and even resale value.
Whether you’re trying to stay warm during brutal Wisconsin winters or cut cooling costs in summer, here’s what Energy Star 7.0 means for you.
What Is Energy Star 7.0?
Launched by the U.S. Environmental Protection Agency, Energy Star 7.0 sets stricter guidelines for how windows, doors and skylights qualify for Energy Star certification.
In short, windows now need to be even better at keeping heat in during the winter and blocking it out in the summer to earn the label.
Why This Matters for Wisconsin Homes
Living in a state that sees both subzero temperatures and hot, humid summers, Wisconsin homeowners benefit more than most from high-performance windows. With Energy Star 7.0:
- You get higher efficiency ratings on qualifying products.
- Your home stays warmer in winter and cooler in summer.
- You may be eligible for federal tax credits or utility rebates on qualified windows.
