DOE Program Offers Volume Pricing on Efficient Windows


WASHINGTON – May 27, 2010
Builders, agencies and volume buyers in search of more
energy-efficient products at cost-effective prices will have a new place to
look.  The U.S. Department of Energy
launched the Highly Insulating (R-5) and Low-E Storm Windows Volume Purchase
Program and Web site
( with an announcement at the National
Association of Home Builders (NAHB) headquarters in Washington, D.C.


Researchers at the Department of
Energy’s Pacific Northwest National Laboratory (PNNL) in Richland, Washington, have been working with window
industry professionals for the last 12 months in an effort to bring
manufacturers and distributors of high performance, energy efficient windows
together with homebuilders, weatherization agencies, educational institutions
and others capable of purchasing large volumes of these windows.


With a reasonably low minimum
order requirement of 15-20 windows, purchasers will be able to peruse the new
program’s Web site to select a Highly Insulating (R-5) or Low-E storm window
from more than 30 manufacturers who have met the requirements of the
program.  Buyers interested in
pricing and specifying more efficient windows simply need to access the
program’s Web site  and
begin their search.


 “The volume purchase program brings new
and emerging technologies to the mainstream market at competitive prices,” said
Graham Parker, project manager for PNNL. 
“High performance windows are ready to enter the market at just the right
time,” said Parker, “when the nation is trying to address energy efficiency, job
creation and savings for consumers.”


While double-pane, low-E, R-3
(U-factor 0.3) windows have typically been considered the standard of energy
efficiency for more than a decade, triple-pane windows (typically R-5/U-factor
0.2) can reduce average heat loss through the window by more than 30 percent,
when compared to R-3 windows in residential buildings situated in northern
climate zones. In situations where full window replacement is not an option,
low-E storm windows can be used to reduce heat loads by up to 20 percent,
allowing them to pay for themselves in just five years in a climate such as


Although triple-pane windows have
been available for decades they have existed primarily as niche products whose
prices made them unsuitable for mainstream market adoption.  The savings for both R-5 windows and
low-E storm windows are a significant improvement over products available today,
and many meet DOE’s price premium target over R-3 (U-factor 0.3) windows of less
than $4 per square-foot.


On the Web site, buyers select
the window type of interest from the homepage.  The buyer then selects the window sizes
of interest from a menu of size and corresponding price ranges for each (lowest
to highest price for that size range). 
A dropdown menu will then appear showing all the qualified suppliers
offering windows of that size range as well as the color and type of frame
material available, and their shipping region in North
.  Clicking on
the link for the supplier will take the buyer directly to that supplier’s Web
site for completing the sale.
