EPA Rep Gives Picture of Current and Future Energy Star Market

February 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.

  1. re, “Plus the[Energy Star] performance requirements keep ratcheting up without enough time in between for the industry to keep up.”

    The writer doesn’t appreciate the fact that ENERGY STAR does not want the industry to “keep up”. They want ENERGY STAR products to be dominant at the top end (25%) of any product category. This means that, if an industry does a great job in meeting the requirements across the board, they have no choice within their overall strategy but to raise the bar yet again.

  2. This moving-target mindset has produced a series of unintended consequences:
    1. Plastic (vinyl) windows with their limited virtues of low cost and low frame u-values have become the dominant residential product.
    2. Architects want to specify green products and gain LEED certification for their commercial projects. The easy spec is to plug in Energy Star u-values, even though Energy Star is not a commercial program.
    3. With the resulting u-value-driven competition among manufacturers, more and more commercial projects end up with either plastic windows or highly modified (expensive) aluminum windows.

    As with most central planning, the broad result is lower quality and/or higher costs. All for the sake of a few u-value points.
