STAR® Update: USGlass Talks to AGC Flat Glass
As part of its continuing coverage of the proposed changes to the
ENERGY STAR windows program, USGlass magazine spoke to Serge Martin,
vice president of marketing for AGC Flat Glass North America, for
the glass company's view of this important matter.
"At AGC we think it's time to finally say it: Consumers often buy
the wrong windows, featuring a glass that does not maximize their
energy efficiency-because the glass was not designed and specified
with their true regional energy needs in mind," says Martin.
He says it's time to end the one-size-fits-all approach to glass.
He gives the example of a window you can find at Home Depot that
is advertised as suitable for any region.
"How can a window in Michigan be the same window that should be
used in South Florida?" he says. "It just doesn't make sense."
While he is pleased to see that the Department of Energy (DOE)
is looking at making the criteria more stringent, he does have some
"We need to make sure we will not end up with a mild compromise.
We need to do something deeper," he said.
However, he does concede that major logical changes, such as requiring
triple-glazed glass in certain regions, would require time for companies
to implement, he says that more appropriate coatings are readily
available from all glass manufacturers.
"A first step towards low solar heat gain low-E glass made sense
in the past," says Martin. "But now it is time to strengthen the
requirements. Some products are worse performers than clear glass…"
In addition to talking to USGlass, AGC is taking steps to raise
awareness in the industry regarding this important issue through
interaction with its customers and other marketing methods.
"We're trying to raise awareness to code bodies, etc., so the appropriate
changes are made," he says.
