National Green Building Standard

  • Oregon , Washington , Idaho , Montana
  • Home Certification Programs

NGBS Green certification, based on the National Green Building Standard™ ICC/ASHRAE – 700, goes well beyond saying a home is energy efficient; it provides independent, third-party verification that a home, apartment building, or land development is designed and built to achieve high performance in six key areas: Site Design, Resource Efficiency, Water Efficiency, Energy Efficiency, Indoor Environmental Quality, and Building Operation & Maintenance. A new or renovated green home or multifamily building can be awarded a Bronze, Silver, Gold, or Emerald certification level, depending on the number of green practices successfully incorporated in its design and construction.
