Comment Period Now Open for NGBS Changes

green puzzle houseThe draft of the 2020 edition of the National Green Building Standard (NGBS) is now open for comment.

Builders, remodelers, code officials – in fact, all members of the public – are invited to take a look at the proposed changes to the standard and submit their opinions. The deadline is Nov. 12.

The changes on the draft are presented an underline-crossout version of the 2015 NGBS.

As an American National Standards Institute (ANSI)-approved standard, NGBS is subject to periodic review and updates as a way to ensure advances in building codes, technology and other developments can be considered for incorporation.

Originally developed by NAHB and the International Code Council, the first edition of the National Green Building Standard was written by a 42-member consensus committee and approved by 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 mixed-use buildings where the residential portion is greater than 50% of gross floor area.

Among other proposals in the draft:

  • A brand-new Chapter 13: Commercial Spaces New Construction for use in mixed-use multifamily buildings
  • A new Chapter 12: Certified Compliance Path for Single-Family Homes, Townhomes, and Duplexes that may be of interest to production builders
  • A new performance path for water efficiency, the Water Rating index, in Section 804 and Appendix F

Home Innovation Research Labs is once again administering the NGBS development process. For additional information, go to HomeInnovation.com/NGBS.
