Learn about the new ENERGY STAR 7.0 program. Beginning in 2023.

Energy Star Requirements for Windows and Doors Have Changed! But Windows Plus Has You Covered.

Make sure your new windows and doors meet the new ENERGY STAR standards.

What's new with ENERGY STAR?

Beginning in October 2023, ENERGY STAR 7.0 raises the bar on window and door efficiency requirements:

  • The minimum efficiency ratings for ENERGY STAR have changed.  Windows and doors need to be more efficient than ever to qualify for ENERGY STAR certification.
  • To be eligible for tax credits, windows now have to exceed the new ENERGY STAR minimum efficiency ratings, and be qualified as “Most Efficient” by ENERGY STAR.

EnergyStar Ratings for Cincinnati
How does the new ENERGY STAR program affect windows & entry doors?

Replacement Windows (North-Central Region):

  • For ENERGY STAR qualification, the minimum U-Factor rating has lowered from ≤ 0.30 to ≤ 0.25.
  • The Solar Heat Gain Coefficient (SHGC) rating is unchanged at ≤ 0.40.
  • To be eligible for tax credits, windows must now meet the “Most Efficient” certification, with a U-Factor ≤ 0.20.
  • Note that ENERGY STAR qualification alone does not qualify for tax credits on windows, unless they’re certified “Most Efficient” with a U-Factor ≤ 0.20!

Entry Doors (North-Central Region):

  • ENERGY STAR qualification & tax credit eligibility depends on the amount of glass in the entry door.  
  • For opaque doors (without glass), the U-Factor is unchanged, at ≤ 0.17.
  • For ≤ 1/2 lite doors (half-glass or less), the minimum U-Factor has lowered from ≤ 0.25 to ≤ 0.23.
  • For > 1/2 lite doors (more than half-glass), the minimum U-Factor has lowered from ≤ 0.30 to ≤ 0.26.
What are the tax credit changes with the new ENERGY STAR program?
  • Tax Credits for Eligible Windows:  30% of the window cost, up to $600 for eligible windows. 
  • Tax Credits for Eligible Exterior Doors:  30% of door costs up to $250 per door, with maximum credit $500.
  • Maximum Annual Tax Credit: There is a $1,200 aggregate yearly tax credit maximum
  • Timing:  The new 25C tax credit is effective from January 1, 2023 through December 31, 2032.
