ICC 700 National Green Building Standard (NGBS)

The National Green Building Certification (NGBS) is built on the ICC 700-2008 National Green Building Standard™, a comprehensive benchmark for sustainable construction and remodeling. This nationally recognized certification is the only residential green building rating system to complete the full consensus process and achieve approval from the American National Standards Institute (ANSI). Its primary objective is to establish a clear and consistent definition of green building practices across the United States.

What Does NGBS Cover?

The NGBS is designed to accommodate diverse residential projects, including:

  • Single-family homes

  • Multifamily housing

  • Residential remodeling

  • Site development projects

It ensures flexibility to account for regionally appropriate green practices, while maintaining a robust framework for sustainable building standards.

Five Key Categories of Sustainability

The certification focuses on five pivotal aspects of sustainable construction, each seamlessly integrated into the building process:

  1. Energy Efficiency: Optimizing energy use to reduce consumption and lower carbon footprints.

  2. Water Conservation: Implementing strategies to conserve water resources, ensuring long-term availability.

  3. Resource Efficiency: Promoting the use of sustainable and recycled materials in construction.

  4. Indoor Air Quality: Enhancing the health and comfort of occupants through improved ventilation and reduced pollutants.

  5. Site Design and Development: Encouraging eco-friendly practices for site selection, preparation, and landscaping.

Achievable Certification Levels

Projects certified under the NGBS can earn one of four distinct certification levels, depending on the extent of their adherence to the Standard:

  • Bronze: Entry-level achievement showcasing significant green features.

  • Silver: Advanced efforts in sustainable building practices.

  • Gold: Exceptional commitment to environmental responsibility.

  • Emerald: The highest level, reflecting superior sustainability and energy efficiency.
