2024 NGBS Comment Period Closing Soon
Home Innovation Research Labs recently released a draft of the 2024 National Green Building Standard (NGBS). The 2024 NGBS Draft 1 includes many changes, such as updating the reference standards to align with more modern versions of the I-codes and introduces new compliance pathways for existing buildings and buildings located in the Tropical Climate Zone.
As an ANSI-approved standard, the NGBS is subject to periodic review and updates to ensure consideration of advances in building codes, technology and other developments. Initiated in 2007 by the International Code Council (ICC) and NAHB, the 2008 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).
Anyone may submit comments regarding the changes shown in the draft version. Only the marked changes and sections directly affected by those changes are open for comment. Comments must be submitted by Oct. 2, 2023.
