Initiated in 2007 by the International Code Council and the National Association of Home Builders, the 2008 National Green Building Standard (NGBS) was the first point-based rating system for green residential construction, remodeling, and land development to be approved by the American National Standards Institute (ANSI). The 2024 NGBS includes numerous changes, such as updating the reference standards to align with more modern versions of the I-codes, and introducing new compliance pathways for existing buildings and buildings located in the Tropical Climate Zone.
The 2024 National Green Building Standard (NGBS) Draft Standard's 45-day public comment period began on Aug. 18, 2023, and research, testing, and consulting firm Home Innovation Research Labs, an ANSI-Accredited Developer, is the administrator for the standard development process.
A PDF version of the Draft Standard, including all changes approved by the Consensus Committee, can be accessed online and is accompanied by a web-based form for submitting comments. Anyone interested is eligible to submit comments on all changes shown in the draft version. Only the marked changes and sections directly affected by those changes are open for comment.
The deadline for submitting comments is Oct. 2, 2023.
Any questions regarding the public comment period or any part of the standards development process should be submitted via Home Innovation's online contact
