NAHB Green

National Green Building Certification is a green residential standard from the National Association of Home Builders (NAHB) and approved by the American National Standards Institute. It's applicable for new and remodeled single-family and multifamily homes as well as residential subdivisions.

Projects can be scored on a point basis to the Bronze, Silver, Gold or Emerald level, each one indicating progressively higher point totals in energy efficiency, resource efficiency, water efficiency, indoor environmental quality, lot and site development and homeowner education and home maintance. Single-family new home projects can also be scored to the Department of Energy's Building America program using the same online tools.

Many of the mandatory measures found in The National Green Building Standard are consistent with the International Code Council's I-Codes. Additionally, the baseline for energy savings has been updated to IECC 2006

The NAHB Research Center trains and accredits local third-party verifiers and after two inspections, the paperwork is sent to the Research Center for approval.
