National Green Building Standard (NGBS)

Image result for NGBS logo


The National Green Building Standard™ certification 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.

 Testing Homes to the Highest Green Standards

 We certify homes to the rigorous requirements of the National Green Building Standard™ (NGBS) – the only residential green building rating system approved by ANSI as an American National Standard. The NGBS provides practices for the design and construction of all types of green residential buildings, renovations, and land developments. 

Our stringent third-party verified certification program ensures homes and apartments are built in compliance with the NGBS and focuses on three primary attributes that are highly marketable to today’s discerning consumers:

 Healthy Homes

  • Providing fresh air ventilation that improves indoor air quality
  • Limiting pollutants and contaminants in the home
  • 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
  • Controlling maintenance costs through durable construction and product selection
  • Providing technical and educational resources to ensure the home’s optimum performance

Sustainable Lifestyle

  • Promoting walkability
  • Reducing home maintenance through enhanced durability
  • Preserving natural resources through responsible land development practices
