What to Know about ENERGY STAR Windows
Your Climate Zone
When it comes to energy efficiency, different climate zones may make a window more or less energy efficient. For example, Florida is in a Southern climate zone per ENERGY STAR certifications.
U-Factor
U-factor is a key metric used by the ENERGY STAR program to determine a window’s insulation. For Southern climate zones, the program recommends windows have a U-factor rating under 0.32.
SHGC
SHGC, or Solar Heat Gain Coefficient, is a measure of how much of the sun’s heat gets through a window. ENERGY Star windows must have an SHGC of 0.23 or lower to qualify as compliant.

Land O’ Lakes ENERGY STAR Windows FAQs
Are ENERGY STAR Windows Worth It?
Purchasing windows that have earned ENERGY STAR certification may be initially more costly than getting basic windows that lack energy efficiency-enhancing features like low-e glass, improved insulation, argon gas fill, and extra layers of glass.
However, the cost over time of the “cheaper” window may be higher in the long run.
ENERGY STAR certified windows provide a consistent long-term savings on energy bills since your home’s climate control system doesn’t have to work quite as hard, saving electricity for your home.
Additionally, because there’s less air leakage with an ENERGY STAR window, you can enjoy enhanced comfort in your home with fewer drafts and less air infiltration.
According to data from an ENERGY STAR estimate, the average homeowner in Jacksonville, FL can save around $536 a year if they replace their clear, single-pane glass windows with ENERGY STAR-compliant windows. However, that’s just an average based on a $0.15 electricity billing rate.
The more energy your home uses to maintain a comfortable temperature, the bigger the savings you can realize for putting in ENERGY STAR v7.0-compliant windows. So, if your home typically needs more energy to keep cool in summer and warm in winter, you stand to save even more money each year by replacing your windows.
In addition to the monetary savings, adding ENERGY STAR windows to your home helps reduce your carbon footprint. This makes them an ideal upgrade for any homeowner who wants to be more environmentally-conscious.
What Is an ENERGY STAR Window?
An ENERGY STAR window is a window that has been certified to meet certain energy performance standards set by the EPA, which are independently tested by the NFRC.
These windows help homeowners reduce their energy consumption for their home’s climate control systems, leading to reduced energy bills and a greener environment.
What are the standards a window needs to meet to be ENERGY STAR v7.0 compliant? The answer actually changes from one “climate zone” to the next.
In northern climate zones, a window would need to have a u factor of 0.22 or less and an SHGC of 0.17 or more to be considered ENERGY STAR certified. However, here in Florida, which is in the Southern climate zone, the u-factor of a window has to be 0.32 or less and the SHGC has to be 0.23 or less.
Why is there a difference between requiring low SHGC in Florida vs higher SHGC in Northern climates? Because, in Florida, the goal for the majority of the year is to keep your home cool. Meanwhile, in northern climates, the goal is to keep the home warmer.
Higher Solar Heat Gain Coefficient values allow more of the sun’s heat inside the home. That’s desirable in the north, but bad in the south where temperatures run high and your air conditioner has to work overtime year-round.
Do ENERGY STAR Windows Qualify for Tax Credits?
ENERGY STAR certified windows can qualify for environmental tax credits IF they meet the “ENERGY STAR Most Efficient” criteria for the climate zone you’re installing your windows in.
If you go to the NFRC’s Certified Product Directory (CPD) search page and find your window on it using the CPD number, check to see if the window has a green shade for your climate area. If it does, it may qualify for “energy efficient home improvement” tax credits.
These tax credits for the 2025 fiscal year can be worth up to $3,200 off your federal income taxes.
However, it is important to note that windows will only count for a part of that maximum tax credit. According to the IRS website, windows can earn up to $600 total tax credits. To get the maximum tax credit, you’ll need to make broader improvements to your home’s energy efficiency. For example, energy efficient doors can earn a tax credit of $250 per door (up to $500 total), and adding new insulation can earn up to $1,200 in tax credits (which also helps ensure you get the biggest energy savings for your home).
What Are the Climate Zones Per ENERGY STAR?
ENERGY STAR separates the USA into four distinct Climate Zones:
- Northern
- North-Central
- South-Central
- Southern
Florida is wholly within the “Southern” region of the ENERGY STAR Climate Zone Map. We’re one of only two states to fall completely within this zone (the other being Hawaii).
So, when checking the ENERGY STAR certification for windows, make sure that they’re certified for the Southern Climate Zone.
Can a Single Window Meet ENERGY STAR Requirements in Every State of the USA?
What makes a window energy-efficient in a northern state may actually make it less energy efficient in a southern state like Florida. However, there are some window products on the market that are universally ENERGY STAR certified in all 50 states of the USA. So, the answer is “Yes, but it’s not likely to meet the ‘Most Energy Efficient’ requirements for tax credits.”
As noted by the ENERGY STAR FAQ page: “A window with a U-factor of less than or equal to 0.27 and a Solar Heat Gain Coefficient (SHGC) of less than or equal to 0.25 could earn the ENERGY STAR in all climate regions.”
However, to get the biggest energy efficiency benefits in Florida, you’ll want to get a window that is tailored for energy efficiency in southern climate zones.
Will Low-E Glass Meet ENERGY STAR Requirements?
Energy Star v7.0 has some strict requirements for windows, doors, and skylights. Using low-e glass in your window or door can help it meet these requirements, but that alone doesn’t guarantee compliance.
When buying new windows and doors, look at the U-Factor and Solar Heat Gain Coefficient (SHGC) figures for that product to see if they meet the program’s requirements.
For windows in the southern U.S. to meet Energy Star v7.0 standards, they must have a U-factor of 0.32 or less and an SHGC of 0.23 or less. Door requirements would be 0.50 or lower U-factor and 0.25 or less SHGC.
Look for the ENERGY STAR mark on the product and verify it through the Energy Star product finder page.
