The International Code Council (ICC) approved a proposal related to unit skylights during its recent code development hearings in Dallas. The proposal, S176-12, sought to add a reference to “tubular daylighting devices” to section 2405.5.5 of the code.

The proposal, put forth by Julie Ruth of JRuth Code Consulting, representing the American Architectural Manufacturers Association (AAMA), will require that tubular daylight devices “be tested and labeled as complying with AAMA/WDMA/CSA 101.I.S./A440.” Previously, the section of the code only referenced unit skylights.

“The overall intent of this proposal is to clarify the requirements for tubular daylighting devices, within the context of skylights and sloped glazing in the IBC,” Ruth wrote in the proposal.

The committee approved the proposal with a slight modification that replaces the words “design pressure” with the words “performance grade rating” in the exception to Section 2404.2, according to AAMA.
