WDMA Wins Key Votes at IgCC Hearings

The scope of the International Code Council's International Green Construction Code will remain limited to commercial construction due to the initial approval of one of the Window and Door Manufacturers Association's proposed amendments at hearings conducted last week in Dallas, the organization reports. Other amendments backed by WDMA removed onerous requirements for comprehensive building service life plans and the installation of permanent shading devices on the exterior of buildings. 

"WDMA's proposals, which received broad support at the hearings, improve the IgCC by exempting most residential construction in-line with the original intent of the IgCC, which was to cover commercial construction," says Jeff Inks, WDMA VP of code and regulatory affairs. "This will avoid conflicts that would be created in jurisdictions that may adopt the IgCC, but already have or wish to establish residential green building programs based on the National Green Building Standard, LEED or other criteria"

WDMA proposals also improve the code by eliminating mandatory building service life requirements which would have mandated the development of comprehensive 60-year "Building Service Life Plans," for every building that included minimum 40-year service life requirements for fenestration, the organization reports. WDMA's amendment makes them an elective based upon the intended service life of the building and building assemblies rather than subjective minimums such as 40 or 60 years.

The elimination of mandatory permanent shading requirements removes significant additional and unnecessary costs to building construction that only discourage the use of dynamic glazing and other innovative products because no credit for their use is given, WDMA officials also note.

Other beneficial amendments based on WDMA proposals and those submitted by other stakeholders impacting the window, door and skylight industry include the removal of unjustified exterior sound transmission requirements for windows and doors and clarification of criteria for required environmental friendly building materials, the organization reports.

Development of the first edition of the IgCC will continue through the end of the year with a second set of ICC hearings scheduled for November 2-6 in Phoenix. All amendments will be final after that, with ICC expected to publish the first edition in March 2012.
