ANSI released several door-, window- and wood-related standards revisions, which are all part of the International Green Construction Code: ANSI/ASHRAE/USGBC/IES – Standard 189.1-2011 Standard for the Design of High-Performance Green Buildings.
The standard was originally published in 2009, so the current 2011 version is a revision. A supplement was published in 2013, and there is a proposed 2014 addendum currently out for public comment, according to ANSI.
The first, a revision of 9.4.1.3 for Bio-based Products, states that “A minimum of 5 percent of building materials used, based on cost, shall be bio-based products. Bio-based products shall comply with the minimum bio-based contents of the USDA’s Designation of Bio-based Items for Federal Procurement, contain the ‘USDA Certified Bio-based Product’ label, or be composed of solid wood, engineered wood, bamboo, wool, cotton, cork, agricultural fibers or other bio-based materials with at least 50 percent bio-based content.”
Additionally, 9.4.1.3.1 Wood Building Components has been revised to read, “Wood building components including, but not limited to, structural framing, sheathing, flooring, sub-flooring, wood window sash and frames, doors and architectural millwork used to comply with this requirement shall contain not less than 60 percent certified wood content tracked through a chain of custody process either by physical separation or percentage-based approaches. Acceptable certified wood content documentation shall be provided by sources certified through a forest certification system with principles, criteria, and standards developed using ISO/IEC Guide 59, or the WTO Technical Barriers to Trade. Wood building components from a vendor are allowed to comply when the annual average amount of certified wood products purchased by the vendor, for which they have chain of custody verification not older than two years, is 60 percent or greater of their total annual wood products purchased.”
Standard 8.3.6.6 Flashing of Fenestration, Door Assemblies, Mechanical Equipment and Other Penetrations of Building Envelope also was revised, now reading, “Flashing or sealants shall be installed around fenestration, door assemblies, and penetrations associated with mechanical equipment and utility services, except where there is a mechanism for drainage to the outdoors or where the materials are designed for long term contact with water.”
