Technical Update: Industry Efforts Keep GANA Members Busy

Members of the Glass Association of North America (GANA) kept busy last month when they met for the association’s Fall Conference, October 13-16 at the Hyatt Regency in San Antonio. Sessions included presentations on codes and standards developments, new technologies and innovations and much more.

The Laminating group is working on a number of projects. The hurricane product substitution document is going through its five-year review update, which the group hopes to ballot soon and possibly publish before Annual Conference. Likewise, the Laminated Glazing Reference Manual, also being updated, has been submitted to staff for review. It, too, will hopefully be published by Annual Conference.

Several presentations were on the Energy Division agenda. Tom Culp of Birch Point Consulting, GANA’s energy consultant, gave an update on various code changes and revisions (see this month’s GANA Perspectives on page 8 for more on this).

There have also been discussions regarding the National Fenestration Rating Council (NFRC) and how to proceed with the Component Modeling Approach (CMA) program. One matter was a software issue that’s now been resolved. Overall there are concerns with the program. Options under consideration include continuing it as is; making changes to it; a merger with the American Architectural Manufacturers Association (AAMA) 507 thermal performance report, or ending it. Culp said there is still a strong need to implement and improve accuracy in the CMA calculations, even if this is used with AAMA 507.

The Fall Conference covered topics such as codes and standards, as well as educational documents, manuals and presentations.
Dr. Helen Sanders also gave a report about the joint GANA/Insulating Glass Manufacturers Alliance (IGMA) Life Cycle Analysis (LCA) Task Group, and talked about the importance of eco-labeling. She said in LEED V4, environmental product declarations (EPD) are included as requirements under materials and resources. In the Green Codes LCA is currently optional, but mandatory in the next revision cycle.

A Product Category Rule (PCR) for windows was published in September. Efforts are now underway to develop a PCR for fabricated glass, including coated, heat-treated, laminated and insulating. Sanders expects a draft for review within a couple of months.

The Tempering Division is continuing to work on a number of documents, including GIBs and an update to the Engineering Standards Manual. GANA technical director Urmilla Sowell discussed the joint efforts with the International Window Cleaners Association (IWCA) to update the Proper Procedures for Cleaning Architectural Glass GIB.

During the BEC session, members discussed the possibility of creating a certification program that would be geared toward individual contract glaziers. The idea would be to educate them about GANA materials and other documents in a professional way.

Stanley Yee with Dow Corning covered the activities of the Building Envelope Commissioning task group. It will inform the glazing industry about what building envelope commissioning is, standards that are applicable and what to expect as it becomes more common.

The Decorative Division also covered a number of working items, including American Institute of Architects educational presentations, GIBs, manuals and more.

One new group will work on viewing quality of decorative glazing products in interior and exterior applications. It will report back during the Annual Conference, March 2-5, 2016, in Palm Springs, Calif.
