EPA’s Anderson Reveals Details on Most Efficient Program for Windows

August 27th, 2012 by DWM Magazine

The Environmental Protection Agency (EPA) hosted a stakeholder meeting today in Washington, D.C., where door, window and skylight companies had the opportunity to offer their views on the latest Energy Star draft, as well as hear about important program updates. This included an update on the future of the Energy Star program reported by Christian Kohler, Lawrence Berkeley National Laboratory, and an update on the Most Efficient program for windows.

First, Kohler posed to attendees, “where do we go from here?” His answers included the increased use of triples in Northern climates, minimum solar heat gain coefficient (SHGC) requirements and dynamic SHGC in all climates. He added that there is potential to look at building orientations within the realms of Energy Star.

“I know it would be a pain for the Energy Star label to take orientation into consideration, but it can make a difference,” he said.

He also mentioned the Most Efficient program as part of Energy Star’s future and Doug Anderson, project manager for the Energy Star Program, offered some additional insights, though he couldn’t divulge all of the specifics just yet.

“We have a good idea of what we want to do and we will propose it in September,” he said.

He affirmed that windows will be folded into the current Energy Star Most Efficient program, which is currently in place for other Energy Star programs. Anderson says the windows program will be similar to what EPA has in place for heating and cooling equipment.

“The program will not include prices,” he said. “I know that was an issue in the windows volume purchase program.”

He added that the agency is considering using the same U-factor specified for the windows volume purchase program, and that the EPA plans to propose a minimum VT rating and will require NAFS certification. Manufacturers will have to fill out forms affirming their products are NAFS certified and then the product lines will be listed on the Most Efficient website beginning in January 2013. Finally, the SHGC will be in line with the latest Energy Star criteria.

Additionally, the Most Efficient designation won’t include a label to be affixed to products, but it may be included in store signage, websites, displays, etc. A stakeholder webinar will take place in mid-September, and the final criteria will be published in October.
