EPA Rep Gives Picture of Current and Future Energy Star MarketFebruary 16th, 2012 by DWM Magazine
Emily Zachery, D&R International, gave an update on the Energy Star program for Windows, Doors and Skylights during the recent meeting of the Insulating Glass Manufacturers Alliance (IGMA), and gave a picture of Energy Star market share for doors, windows and skylights.
According to Zachery, a Ducker Research Study looking at the Energy Star Market Share Data for 2010 shows that windows comprise 81 percent of the market, doors 71 percent, and skylights 99 percent.
Despite the change in criteria in January 2010, windows market share increased 5 percent, doors 1 percent and skylights held firm at 99 percent.
Zachery’s presentation also included a review of the preliminary criteria range as well as other information regarding doors and windows qualifying in various zones.
Statistics were given regarding items such as the U-factor distribution of doors by glazing level (middle), and attendees were given a picture of windows meeting current equivalent energy performance criteria (bottom).
Finally, an update was given on the next criteria revision in which the EPA is slated to announce its draft criteria and analysis report in March 2012. Margaret Webb, IGMA executive director, says many of the questions from attendees centered around the NFRC’s blind verfication program and questions regarding the proposed Energy Star requiements.
“I think everyone’s leery of this blind verification program and it’s costs,” says Webb. “Plus the[Energy Star] performance requirements keep ratcheting up without enough time in between for the industry to keep up. R&D takes some lead time and the government folks don’t seem to appreciate that. ”
More information on the proposed revisions, as well as submitted public comments, may be found on the Energy Star website.
