What criteria does NAHB GREEN use to score homes?
NAHB Green is based on the NAHB Model Green Home Building Guidelines, which were developed in 2005 for single-family homes. Builders also have the option of scoring homes to the National Green Building Standardâ„¢ which adds guidance for remodeling and multifamily construction; and suggests higher thresholds and new requirements in many existing categories. The Standard was recently approved by the American National Standards Institute (ANSI), an organization whose approval ensures that a balanced committee vetted the criteria through a transparent and rigorous process; and that the result is unbiased toward any interests.
