Since 2009, the ICC-700 National Green Building Standard (NGBS) has offered a flexible, rigorous, and affordable path to residential third-party green certification. Over 225,000 homes and apartments have earned NGBS Green Certification, and over 130,000 homes are in-process to earn certification. ANSI recently approved the 2020 NGBS version, the fourth version to date, with an expanded scope that applied to mixed-use buildings, assisted living facilities, hotels, dormitories, and more. The 2020 also includes: a streamlined certification for single-family homes; a certification path for commercial space of mixed-use buildings; greater flexibility for existing buildings being renovated or converted; a new performance path for water efficiency; and new practices that are designed to promote resiliency, universal design, and wellness.
