NATIONAL GREEN BUILDING STANDARD
The National Green Building Standard (NGBS) goes well beyond saying a home is energy efficient; it provides independent, third-party verification that a project is designed and built to achieve high performance. NGBS offers four levels of certification including Bronze, Silver, Gold and Emerald and can certify single family or multifamily renovations or new construction as well as land development projects.


NGBS relies on six key areas to achieve high performance: Site Design, Resource Efficiency, Water Efficiency, Indoor Environmental Quality, and Building Operation & Maintenance.
Southface verifies homes to the rigorous requirements of the ICC 700 National Green Building Standard™ - the only residential green building rating system approved by ANSI as an American National Standard. NGBS provides practices for the design and construction of all types of green residential buildings, renovations, and land developments.
NGBS's stringent third-party verified certification program ensures homes and apartments are built in compliance with the program standards and focuses on three primary attributes that are highly marketable to today's discerning consumers.
- Healthy Homes - limiting pollutants and contaminants in the home and preventing moisture problems that can contribute to mold and attract pests
- Lower Operating Costs - reducing utility costs through cost-effective energy and water efficiency practices, durable construction and product selection, and providing technical and educational resources to ensure the home's optimum performance
- Sustainable Lifestyle - promoting walkability and preserving natural resources through responsible land development practices
