- Colorado Springs: This jurisdiction has delayed full adoption until 2027 and maintains slightly more flexible thresholds, requiring a U-value of 0.35 and an SHGC of 0.30.
- Energy Star Alignment: The new thresholds are designed to align with the Energy Star window requirements 2026 Colorado standards. Selecting high-performance products, such as fiberglass windows, helps meet these benchmarks.
- Tax Credit Eligibility: Homeowners who install windows meeting these heightened standards may become eligible for the Energy Star Most Efficient 2026 tax credit, helping to offset the cost of high-performance upgrades.
