This is a legacy version of the WELL Building Standard. Please check the latest version here.

Organizational Structure

WELL is the culmination of seven years of rigorous research in collaboration with leading physicians, scientists and industry professionals. The WELL Building Standard® was pioneered by Delos and is managed and administered by the International WELL Building Institute (IWBI). The WELL Building Standard is third-party certified through IWBI’s collaboration with the Green Building Certification Institute (GBCI) – the certification body for the LEED® Green Building Rating System.

International WELL Building Institute, PBC (IWBI)

The IWBI is a public benefit corporation (B-Corp) that is dedicated to transforming buildings to support the health and wellness of the people who live, work and go to school in them. Public benefit corporations are an emerging U.S. corporate structure for corporations committed to balancing public benefits with profitability – harnessing the power of private capital for greater good. Delos created the IWBI as a subsidiary devoted exclusively to managing and sharing the WELL Building Standard globally pursuant to a Clinton Global Initiative commitment to improve the way people live by developing spaces that enhance occupant health and quality of life.

The IWBI has committed to direct 51% of net profits, after taxes, generated by WELL Building Certification project fees toward charitable contributions and impact investment focused on health, wellness, and the built environment.
