NAHB Green Standards

NAHB collaborated with the International Code Council (ICC) to develop an ANSI standard for green building practices. This standard, known as the National Green Building Standard (NGBS), provides a system for certifying homes as green buildings, awarding points to homes based on the design and material choices made in constructing the home. The NAHB credits listed in this brochure are based on the final version of the standard, approved by ANSI in early 2009.
