1	U.S. Department of Energy. Savings estimates based on population-weighted regional annual energy use for a 2,000 sq. ft., single-story, detached house with 300 sq. ft. of
window area, gas heat, and electric air conditioning. Estimates use the Energy Information Administration's 2005 average gas prices and year-to-date through June 2006
electricity prices. Double-paned, clear-glass may not be applicable to all jurisdictions due to mandatory building codes. Actual savings will vary by climate region and
home characteristics.
2	The savings estimates apply to both new construction and replacement applications with the following two exceptions: savings from double-paned, clear glass windows
in new construction in the West South Central and East North Central are $85 and $80 respectively.
MORE THAN JUST DOLLAR SAVINGS
New ENERGY STAR-qualified windows can help reduce your energy bill up to 15%.
Estimated savings vary from region to region depending on current heating and
cooling costs and are generally greatest where there are hot summers, cold
winters or both.
In addition, ENERGY STAR-qualified windows, doors, and skylights do more than
just lower energy bills—they deliver more comfort, create less condensation,
and protect your valuables from sun damage better than conventional clear-glass
double-paned alternatives.
BENEFITS WHEN IT'S COLD
PROTECTION FROM WINTER CHILLS
On cold winter nights, do you avoid seats near the window? The cold, inside surface
of an inefficient window pulls heat away from your body, so you can feel chilly in a
sweater with the thermostat at 70 degrees. With ENERGY STAR-qualified windows,
the interior glass stays warmer, so you can enjoy your window seat even when the
temperature outside dips well below freezing.

When shopping for windows, look for the ENERGY
STAR label to determine if the product is qualified
in your area. For more purchasing tips, visit
www.eneravstar.aov/windows.
REDUCED CONDENSATION
On winter mornings, is the fog on the inside or the outside of your windows? If an
inefficient window or window frame gets too cold, indoor moisture can condense
or even freeze on the interior surface and then pool on the sill. Over time, chronic
condensation can damage sills, cause paint to crack, and encourage the growth of
mold. Advanced technologies enable ENERGY STAR-qualified windows to keep the
interior of the glass and frame warmer, reducing the potential for condensation and
ensuring a clearer view on winter mornings.
BENEFITS WHEN IT'S WARM
SHIELDING FROM SUMMER HEAT
In summer, do your windows seem like giant heat lamps? A typical double-paned,
clear-glass window allows approximately 75% of the sun's heat into your home.
Most ENERGY STAR-qualified windows transmit much less heat, usually without
reducing visible light. You get the light but a lot less heat.
SAFEGUARDING VALUABLE INTERIORS
Your favorite photograph, your child's artwork, even your couch can fade or discolor
after repeated exposure to direct sunlight. Most Low-E coatings—the same coatings
that keep out the summer heat—can reduce fading by up to 75%. These coatings act
like sunscreen for your house, blocking damaging ultraviolet rays without noticeably
reducing visible light.

Orienting windows to the south and planting trees
on the east and west helps reduce energy use.
FINANCIAL INCENTIVES
FEDERAL TAX CREDITS
Consumers can receive a tax credit of 10% of the cost (up to $200 total) for purchasing
ENERGY STAR-qualified windows and skylights. The incentive is even higher for
exterior doors, which may qualify for a tax credit of 10% of the cost (up to $500).
Some restrictions apply. Visit www.eneravstar.aov/taxcredits for more information.
Please consult a tax professional for complete guidance.
LOCAL REBATES
Financial incentives for purchasing ENERGY STAR qualified windows, doors, and
skylights are available in several states. (See chart to the left). For a more detailed
list and contact information, visitwww.eneraystar.gov/rebatefinder.
ENERGY SAVING TIPS
PROPER INSTALLATION
To get the most out of your windows, doors, and skylights, have them installed
by trained professionals according to manufacturer instructions. Otherwise, your
warranty may be void. When hiring a contractor, interview candidates and ask
for references.
WINDOW ORIENTATION
When building a new home, or planning a major addition, consider this: orienting
windows to the south and using roof overhangs can help reduce energy use by
providing shade from the sun in the summer and solar heat gain in the winter.
Overhangs are much less effective against the lower angles of the east and west
sun, therefore reducing the size and number or east and west facing windows
can help reduce energy use.
PLANT A TREE
Strategically planting deciduous trees near south, east, and west-facing windows
will provide needed shade in the summer, but let the sun's heat in during the winter.
HOME SEALING
If you add up all the hidden air leaks in your home, they can equal a hole the size of an
open window! To maximize home efficiency, seal all the gaps where air can leak in or
out, including those around windows, doors, wiring holes, recessed lights, plumbing
vents, your attic hatch, and more. Stopping drafts can make you feel more comfortable
and reduce energy bills. To find out more, visit www.eneravstar.aov/homesealina.

ENERGY STAR CRITERIA
The ENERGY STAR criteria for residential windows, doors, and skylights are tailored
to four Climate Zones: Northern, North/Central, South/Central, and Southern. A product's
energy efficiency for a given climate is based on its impact on heat gain and loss in
cold weather, and heat gain in warm weather. Windows that are energy efficient
in Florida will not necessarily be energy efficient in Michigan and vice versa.
The current four-zone criteria for ENERGY STAR windows, doors, and skylights went
into effect in August of 2003 and was subsequently amended to include alternative,
performance based, criteria for the Southern and South/Central zones (excluding
California). The amended criteria went into effect in September of 2005.
To be eligible for ENERGY STAR, products must be rated, certified, and labeled
for both U-Factor and Solar Heat Gain Coefficient (SHGC) in accordance with the
procedures of the National Fenestration Rating Council (NFRC) at levels that meet
the following ENERGY STAR qualification criteria in one or more Climate Zone.

17	Zero energy savings and positive dollar savings occur simultaneously because electric cooling costs per Btu through June 2006 in California were
more than three times those for gas heating per Btu. The greater savings per Btu of electricity outweigh the increased heating costs leading to
overall monetary savings.
18	Anomolies such as negative savings (costs) occur when the cooling energy savings from ENERGY STAR qualified windows are less than the heating
energy penalty, resulting in slightly greater average energy use than double clear windows.
