From Energy to BIM
AAMA Members Accomplish Much at Summer Meeting
by Debra Levy
When members of the American Architectural Manufacturers Association (AAMA) met in June for its summer Conference in Hershey, Pa., there were two large issues looming before window manufacturers. Both of these involved regulations in California that are most likely moving nationwide.
The first is the adoption of the California Air Resources Board’s (CARB) regulations about formaldehyde emissions by the Environmental Protective Agency, effective January 1, 2009. These regulations, which have been particularly difficult for window manufacturers in California, were expected to expand nationwide next year but as of press time, it seems this won’t happen nationwide for now (for more on this issue, see article on page 20).
The second was a discussion of another California regulation, AB 2505, which concerns PVC packaging (see news story on page 12). It, too, is expected to expand to include the whole nation. “This is really going to be difficult on a lot of window manufacturers,” said one manufacturer representative, who requested to remain unnamed. “All our company does is ship in PVC—and this will require major review.”
“It was one thing when it was just California,” said another, “but this will affect everyone now.”
Wind-Driven Rain Standard is Delayed
The vast majority of door and window testing is based on AAMA/WDMA/CSA 101/I.S. 2/A440, says AAMA president and CEO Rich Walker. “But the water penetration test pressures are much higher than 101/I.S. 2/A440, and AAMA 520 includes the ASTM rapid pulsating pressure test. This more closely represents the conditions during a hurricane,” he says.
The standard was balloted through the general AAMA membership and all comments were resolved. “However, after it was learned that further pulse testing was required to ensure repeatability, the Certification Policy Committee recommended that the new document undergo a 12-month review of validation testing and analysis before publication,” says Walker.
To make sure this occurs, all accredited labs will have the opportunity to evaluate the standard through testing.
So What Exactly Does Green Look Like?
Members of the group discussed energy performance requirements of fenestration products and there are four potential alternatives that were discussed.
1. Establish minimum, mandatory entry-level criteria that are tied to compliance with an independent thermal rating program such as Energy Star. While this sets a convenient baseline for energy performance it also has two substantive limitations: ties the program to criteria that are outside AAMA’s control; and defaults the available marketplace to the approximately 25 percent being targeted by the Department of Energy (DOE);
2. Define prescriptive, possible code based, minimum requirements for energy performance;
3. Establish a features based, non-prescriptive path that gives points for energy performance components such as low-E glass, low conductivity frames, warm-edge spacers, etc.; and
4. Disregard energy performance altogether in favor of currently established programs and focus on ‘renewable/recyclable’ qualifications. This addresses the more typical aspects of green programs but also allows a window with a U-factor of 0.75 to be used in Minnesota.
Rogers said the task group is targeting AAMA’s 2009 Annual Meeting for submittal of the first draft specification document.
It was also reported that AAMA has sent a letter to the U.S. Green Building Council (USGBC) requesting that the two groups work together on the development of sustainability guidelines for fenestration projects.
The recycling of windows—not just the glass in them—was also discussed. “We have to create an end-of-life reclamation for windows,” said Matt Dewitt of Omniglass. “The perception is that windows themselves cannot be actively recycled.”
During the conference, DeWitt chaired the first meeting of the Fiberglass Green and Sustainability Committee as it began the task of developing a scope and mission. “This is going to be a difficult task,” said DeWitt, “but that was true of the vinyl group when it started out as well.”
By the end of the meeting, the group had developed a draft of a scope, which includes identifying the strengths of fiberglass, developing technical solutions to improve the message; and developing communications to disseminate the message.
DOE Representative Forecasts Future Changes for Industry
He talked about what types of changes to expect from DOE in the future. “You’ve seen the ‘Efficient Windows’ program for residential windows,” he said. “We are moving toward something similar in the commercial arena.” LaFrance said while the original proposal for the revised Energy Star criteria was expected to include three phases, DOE is now reducing that to two phases. He also mentioned that it is being developed under the assumption that “krypton gas is not available,” citing the recent shortage of the gas in industrial markets. (See related story in the June 2008 issue of DWM, pages 4 and 6).
“I realize that some of the things we propose increase costs,” he said, “but if those things are mandated, then it’s better, because it applies to everyone.”
LaFrance also took the skylight industry to task. He mentioned that the Preliminary Energy Star Criteria for Skylights did not show much improvement over the last one. “I don’t know why skylights can’t do better,” he said, adding that he expects changes in other areas as well.
“There is no reason you can’t add insulating glass criteria to the codes,” he said, “none.”
“DOE has recognized that you shouldn’t use the same glass in Maine that you use in Texas, and you’ll see that reflected,” he said.
Outlining Industry Trends
Michael Collins #1, vice president of Jordan, Knauff and Company, an investment banking firm in Chicago, specializes in the door and window industry and writes a monthly column in DWM magazine. He gave an expansive overview of what’s happening in that industry and crammed tons of statistics into his one-hour presentation. Among his comments about the U.S. housing market were
At the bottom of a business cycle such as this one, Collins says there is a “festival of wealth destruction” that takes all types of wealth out of the market. He also reminded the audience that the commercial market lags behind residential by 12 to 18 months.
Collins expects the nonresidential construction market to grow five percent this year, but he cautioned about the factors that are hurting the business. “There seems to be a lack of coordination among the various standard and code writing organizations; this creates an artificial tax, or a lot of additional cost for the industry,” he said.
He said the glass industry continues to defy description. “There are some companies that pay up to 25 percent more for exactly the same glass as another company buys. There is no good reason for this. I had someone tell me that if the glass industry woke up, they would buy their glass by the pound, rather than the square foot.”
“We are still seeing a ton of activity in door and window companies,” he said. “And the multiples have remained a steady four to seven times EBITA, saving the best nugget of information for close to the session’s end. “The problem is that the EBITA has come down in the last 18 months, not the multiples.”

“First we had line drawings, then AutoCad that you see so prominently today. The difference is that when you make DWG files, the lines and arcs don’t know what they are-a square is a square. With BIM they can live and breathe intelligently. Those squares have information saying whether it’s a door or a window or a piece of glass. The whole process is parametric.”
Collins used EFCO Corp. as an example (“I’ll pick on Dave Hewitt because he’s not here,” he joked.). “EFCO offers one window with more than 6,000 variables. With other programs you have to draw that 6,000 times. With BIM, you make one window and then 6,000 parametric variables. The new generation of Internet-driven design engineers will design this way. It’s already here.”
AAMA Awards its Annual Scholarships
AAMA’s next meeting will be held September 21-24, 2008, at the Hyatt Regency Hill Country Resort and Spa in San Antonio.
