NAHB Green Building Standard
NAHB Green Building Standard

ANSI Approval

The NAHB (National Association of Home Builders) developed the NAHB GREEN BUILDING STANDARD to establish a much needed nationally recognizable standard definition of GREEN BUILDING.  The resulting ANSI (American National Standards Institute) approved ICC (International Code Council) 2008 NATIONAL GREEN BUILDING STANDARD is now available for use in the certification of residential construction to bronze, silver, gold and emerald levels.

It is the only Green Building program in the U.S. to receive ANSI approval.

The Standard

The NAHB GREEN BUILDING STANDARD is a comprehensive systems approach to building and certifying a GREEN HOME.  It uses a points system where the builder must meet certain mandatory requirements and then can select from many building technologies and products to earn additional points to achieve the desired certification level. To learn more, visit www.nahbgreen.org.

To receive certification a builder must meet requirements in all of these areas:

  1. Lot design, preparation and development.
  2. Resource efficiency and Durability
  3. Energy efficiency
  4. Water efficiency
  5. Indoor environmental quality
  6. Building Owner Education in the operation and maintenance of the home

Independent Verification

The NAHB Research Center trains, tests, and accredits Verifiers who review the design and inspect the home during construction to verify that all green practices that the builder claims toward green certification have actually been incorporated into the home.
