Starting March 15, 2019, the 45-day public comment period for the Draft Standard of the 2020 edition of the National Green Building Standard (NGBS) is open.
As part of the American National Standards Institute (ANSI) consensus process, ANSI accredited Home Innovation Research Labs opened a public comment period here with a PDF of the Second Draft Standard, including all changes approved by the Consensus Committee during its meeting in February 2019, along with a web submittal form including submission comment guidelines and instructions. To submit comment on the changes shown as underline/strikethrough text in the Second Draft Standard may do so until the deadline April 29, 2019.
As an ANSI-approved standard, the National Green Building Standard is subject to periodic review and updates as a way to ensure that advances in building codes, technology, and other developments can be considered for incorporation. Initiated in 2007 by the International Code Council (ICC) and National Association of Home Builders (NAHB), the 2008 National Green Building Standard (NGBS) was developed by a 42-member Consensus Committee and approved by the American National Standards Institute (ANSI) in January 2009, making it the first point-based rating system for green residential construction, remodeling, and land development to be approved by ANSI. The 2020 NGBS has an expanded scope that allows for the rating system to be applied to mix-use buildings where the residential portion is greater than 50 percent of gross floor area.
