Existing Buildings

Once published, the Existing Buildings (EB) Standard will provide 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. This 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 provide performance feedback to owners and communities on indicators such as energy and water performance.

The EB Standard will apply to a broad range of existing commercial and multifamily building types, including offices, multifamily, health care, schools, universities, laboratories, industrial, retail, etc.

The Standard will include a points-based assessment and rating system that allows users to identify solutions for actions likely to achieve performance levels commonly accepted for desirable environmental and related efficiency outcomes.

The six Assessment Areas within the Standard include Environmental, Social, & Governance (ESG) Management, Site, Energy, Water, Materials, and Indoor Environmental Quality.

The Existing Buildings Draft Standard is expected to be published by ANSI in the summer of 2023 and released to the public as Green Globes for Existing Buildings 2023 in fall 2023.
