Types of Certification Available for Green Residential Construction

  1. Many standards to choose from:
    1. LEED for homes
    2. NAHB Green Building Certification http://www.nahbgreen.org/Certification/homecertification.aspx
    3. Energy Star
    4. Proposed Standard 189, Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings, is being developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) standard

e. American National Standards Institute (ANSI). The resulting ANSI approved ICC-700-2008 National Green Building Standard defines green building for single and multifamily homes, residential remodeling projects and site development projects while still allowing for the flexibility required for regionally-appropriate best green practices. Similar to the NAHB Model Green Homebuilding Guidelines, a builder, remodeler or developer must incorporate a minimum number of features in the following areas: energy, water, and resource efficiency, lot and site development, indoor environmental quality, and home owner education. The more points accrued, the higher the score. The Standard, however, includes more mandatory items and suggests that higher thresholds be met in several categories. A new threshold - "Emerald" - was added to denote the highest achievement in residential green construction.
