The Existing Buildings (EB) Standard provides a method for assessing existing commercial and multifamily buildings relative to the tenets of integrated design and contemporary best practices for high-performance green buildings. The assessment method addresses the evaluation of buildings with respect to reducing life cycle resource consumption, waste, and global/regional/local environmental impacts contributing to human and ecological system health, and provides performance feedback to owners and communities on indicators such as energy and water performance.
The EB Standard applies to a broad range of existing commercial and multifamily building types, including offices, multifamily, health care, data centers, schools, universities, laboratories, industrial, retail, etc.
ANSI/GBI 02-2025, Assessment Protocol for Existing Buildings, was published in the summer of 2025 and is now in Continuous Maintenance.
