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 the National Association of Home Builders, 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). The 2024  NGBS DRAFT 2 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.
