Many Approved ICC Code Proposals
Will Affect Glass Industry

A number of code proposals pertaining to the use of glass and glazing products were up for discussion when the International Code Council (ICC) held its committee action hearings April 21-30 in Dallas. Proposals were presented on behalf of a number of industry organizations, such as the Glazing Industry Code Committee (GICC) and the American Architectural Manufacturers Association (AAMA), among others. Take a look at this recap of some proposals and their results.

• A proposal to revise Table C407.5.1(1) in the International Energy Conservation Code (IECC) was approved. Presented by Thomas Culp of Birch Point Consulting LLC on behalf of the GICC, the change adjusts the wording in the table to read “Opaque Doors” rather than “Doors.” It also changes “Glazing” to “Vertical Fenestration Other than Opaque Doors.”

According to Culp, “This corrects the terminology in the performance path table to be consistent with the rest of the chapter. Doors can include both glazed and opaque doors, but the intent was clearly meant to be opaque doors, since it is referring to only the U-factor in Table C402.2 ... This proposal clarifies the three fenestration rows as ‘opaque doors,’ ‘vertical fenestration other than opaque doors’ and ‘skylights.’”

• A proposal that will adapt the IECC commercial portion to note that doors with more than 50-percent glass area “shall meet the provisions of Section C402.3.3 for vertical fenestration” also passed. The proposal, CE133-13, was put forth by Jeremiah Williams of the U.S. Department of Energy. In addition, the change adds a section to the code that defines “opaque doors” as “doors that are at least 50-percent opaque in surface area.”

• CE36-13, which aimed to add a requirement that the location of daylight zones on floor plans be included in construction documents to section C103.2 of the IECC, “Information on construction documents,” was approved. The proposal, filed by Culp on behalf of the GICC, “will help code enforcement by reformatting this section as a clear list rather than a cluttered paragraph, and also adding a requirement to show the location of daylight zones on floor plans, which will aid enforcement when daylight zones are used in sections C402.3.1-C402.3.3 (window and skylight area and properties), C405.2.2.3 (daylight controls) and C406.3 (efficient lighting path).”

• The committee also approved CE75-13, which will adapt section C401.2.2 of the IECC. The change was proposed by a variety of groups including the Alliance to Save Energy and the Energy Efficient Codes Coalition. Proponents noted that “the purpose of this code change is to create a new code section to clarify that whenever an entire new fenestration product or assembly replaces some or all of an existing fenestration product … the new fenestration product must meet the U-factor and SHGC requirements of the fenestration table. Section C401.2.1 of the 2012 IECC already requires that additions, alterations and repairs comply with C402 (thermal building envelope) – as a result this proposal does not add any additional requirements. However, this proposal will further clarify the application of the requirements, increase effective enforcement, and reduce the likelihood of confusion and differing interpretations.”

• CE148, also proposed by Culp on behalf of the GICC, was approved. It will adjust section C402.3.2 of the IECC to change the definition of “minimum skylight fenestration area” to apply to a space greater than 2,500 square feet, rather than the previous 10,000 square feet.

• RE5-13, proposed by Shaunna Mozingo of City of Cherry Hills Village, representing the Colorado Chapter of ICC Inc., was approved and removes Section R202 from the IECC. The section had defined entrance doors as “fenestration products used for ingress, egress and access in nonresidential buildings, including, but not limited to, exterior entrances that utilize latching hardware and automatic closers and contain over 50-percent glass specifically designed to withstand heavy use and possibly abuse.”

• RE68-13, proposed by Daniel Walker of Thomas Associates Inc., representing the National Sunroom Association, sought to revise section R402.3.5 of the International Residential Code (IRC). It proposed setting the U-factor requirements the same for all the climate zones where requirements exist, and “would correct [a] discontinuity in the code between the requirements in Climate Zones 2, 3 and 4.” The proposal was approved.

• EB37-13, proposed by John Williams, chair of the ICC’s ad hoc committee on healthcare, and Carl Baldassarra, chair of the ICC code technology committee, was approved as submitted. The proposal suggested that in section 805.5.2, nursing homes be added to the types of buildings in which the code requires that “all transoms in corridor walls in work areas shall either be glazed with ¼-inch (6.4 mm) wired glass set in metal frames or other glazing assemblies having a fire-protection rating as required for the door and permanently secured in the closed position or sealed with materials consistent with the corridor construction.”

• EB15-13, proposed by Jeff Inks of the Window and Door Manufacturers Association (WDMA), was approved with modifications. The proposal sought to adapt sections 702.4, “Window opening control devices,” and section 702.5, “Emergency escapes and rescue openings.”
