R5 Window Program May Expand to
The Department of Energy (DOE) is considering
expanding its R5 volume purchase program to include a commercial aspect,
according to a recent webinar on the topic.
“We’re considering adding different window types, windows for more commercial
building applications,” said Graham Parker of Pacific Northwest Laboratories,
who was one of several speakers.
He added that the commercial component would focus mainly on high-rise
buildings above three stories.
In addition, Parker advised that his company, which has worked with DOE
on the program development, is looking at raising the structural performance
grade required by the program, “as suggested by window vendors and buyers.”
DOE also is considering changing some of the specifications required of
the windows included, Parker said; for example, the possibility of adding
a regional solar heat gain coefficient to the program.
Targeted audiences of the R5 program include homebuilders, contractors,
weatherization agencies, apartment owners and operators, non-profit agencies
and state and local governments.
Christian Kohler, with the windows and daylighting research group of the
Lawrence Berkeley National Laboratory, explained that one goal of the
program is to reduce carbon emissions, “starting with buildings.”
“The window is responsible for 15 to 17 percent of energy use,” he said.
“That represents $13 billion a year in energy costs.”
Nils Peterman of the Alliance to Save Energy, a program led by the University
of Minnesota, explained that one important aspect of the R5 program is
the breadth that it covers.
“Another important aspect is that all the different components of the
window are being accounted for—it’s not just the glass or frame system,”
