Energy costs are rising, but so are energy efficiency standards. If you’re a Wisconsin homeowner considering window replacement, you need to know about Energy Star 7.0 before making any decisions. Windows affect your comfort, utility bills, and even your eligibility for tax credits, so it is essential to be an informed shopper.
What is Energy Star 7.0?
Energy Star 7.0 is the latest version of the EPA’s energy efficiency standards for residential windows, doors, and skylights. It significantly tightens the performance requirements for windows to qualify as “Energy Star certified.”
If you’re shopping for replacement windows today, the bar is higher than it was just a few years ago.
Why It Matters in Wisconsin
In a climate like ours, where winter temps often dip below zero, and summers bring 90°F+ days, window performance is critical. Poor insulation and outdated glass technology can lead to:
- Drafty rooms in winter
- Overheated living spaces in summer
- Sky-high energy bills all year round
Energy Star 7.0 helps ensure the windows you buy are built to handle extreme weather.
Do Renewal by Andersen Windows Meet Energy Star 7.0?
Yes, and many of our window packages exceed these standards.
Our windows feature:
- Fibrex® composite frames for superior insulation and strength
- High-Performance Low-E4® SmartSun™ glass, our most energy-efficient option

Bottom line: we design and install windows that stand up to Wisconsin weather year-round.
Why Installation Still Matters
A top-tier window can still underperform if it’s not installed correctly.
That’s why Renewal by Andersen handles everything in-house. We ensure:
- Airtight seals

It’s not just the window, it’s the entire system.
