Door and window manufacturers who want to give their input on the latest Energy Star draft, may want to plan to attend the U.S. Environmental Protection Agency’s (EPA) stakeholder meeting to be held August 27 in Washington, D.C., and via webinar. The purpose of the meeting is to discuss the Draft 1 Version 6.0 Criteria Revision and Analysis. The registration deadline for the meeting and the webinar is Monday, August 20.

The meeting and webinar are scheduled to last from 9:30 a.m. to 3:30 p.m. and a draft agenda is available. However, space is limited so those who want to attend should email and specify whether they want to attend via webinar or in person.

Some in the industry already have weighed in on the draft that was released in late July. Steven Toth, owner of Cadillac Windows based in Southfield, Mich., says that instead of worrying about lowering U-factors, which in many cases means moving to triple-pane glass, that the EPA should propose a deadline for new technologies.

“Glass companies, in coalition with window manufacturers, need to develop new products that not only improve the U-values but also include an accelerated test for structural integrity over say, a five-year period,” says Toth.

Robert Maynes, director of marketing and international sales, Mathews Brothers in Belfast, Maine, says he is hoping to attend the meeting via webinar, and spoke to DWM about some concerns he has in the draft.

“We see a problem with use of low-E on surface 4,” he says. “As a company we choose not to do that. We think the drawbacks far outweigh the benefits so we would like to see a condensation resistance factor number on there.”

He also says that Energy Star shouldn’t be driven solely by chasing a particular U-value. “We would like to see a visual transmittance (VT) number as well,” he says. “We have a product that allows us to meet a particular U-value without sacrificing VT and without using a coating on surface four … Sometimes in order to get a good U-value you may be sacrificing other factors.”

Stay tuned to for more on the stakeholder meeting.
