Look for this mark. It’s proof that your home is green!
The foremost green rating system for residential construction in the United States, the ICC 700 National Green Building Standard can be used for rating new and remodeled single- and multifamily buildings as well as residential subdivisions. It is the first and only such residential green rating system to have earned the approval of the American National Standards Institute (ANSI).
What is green building? Green homes incorporate environmental considerations and resource efficiency into every step of the building and development process to minimize environmental impact.
The Rating System:
The National Green Building Standard (ICC 700 or “the Standard”)* is the only residential green building rating system approved by ANSI, the American National Standards Institute, as an American National Standard. The Standard provides practices for the design, construction, and certification of green residential buildings, renovations, and land developments. It also sets requirements and environmental performance levels for green buildings and developments.
Under the Standard, green building practices are assigned point values. A home can attain one of four performance levels — Bronze, Silver, Gold, or Emerald — depending on how many green practices are included in the single-family home or the multifamily building. For a building to attain any certification level, all of the applicable mandatory provisions must be correctly implemented. In addition to the mandatory provisions, the Standard requires the home to include sufficient green practices in each of the six categories of green building practices to meet the category minimums for each green level. As an ANSI-approved green building rating system, the Standard provides builders with a credible definition of green home. Since it provides a flexible, expansive point-based system for certification, it also offers builders a process to build affordable green homes that meets their goals, appropriate for the climate, and meets the needs of the market and homebuyers

Green Approved Products:
Green Approved Products are products that the NAHB Research Center has approved as being eligible to contribute points toward certification of a building under the National Green Building Standard™. Such products, when appropriately used, enable builders to earn points toward certification of the building. The NAHB Research Center Green Approved mark is intended to assist builders, designers, and specifiers in identifying products that can contribute points toward building certification. The NAHB Research Center Green Approved mark is also intended to facilitate the verification of the “green” practice incorporated into the building during field inspections by providing the accredited verifier with assurance that the product is eligible for the points claimed by the builder. All buildings for which certification by the NAHB Research Center is sought are required to be inspected by independent, third-party, accredited verifiers to confirm that the building has incorporated sufficient “green” practices to earn the points claimed for the certification level sought by the builder.
