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, is administered by the International WELL Building Institute™ (IWBI™), and is third-party certified through IWBI’s collaboration with Green Business Certification Inc. (GBCI) – the certification body for the LEED Green Building Rating System.

International WELL Building Institute, PBC (IWBI)

IWBI is a public benefit corporation whose mission is to improve human health and well-being through the built environment. Public benefit corporations like IWBI are an emerging U.S. structure for corporations committed to balancing public benefits with profitability – harnessing the power of private capital for greater good. IWBI administers the WELL Building Standard (WELL) – a performance-based system for measuring, certifying, and monitoring features of buildings that impact the health and wellbeing of the people who live, work, and learn in them. Fulfilling the vision of IWBI Founder Paul Scialla, IWBI has a pioneering altruistic capitalism model that will address social responsibility and demonstrate a sustainable model for philanthropy. IWBI has committed to direct 51% of net profits received from WELL Certification project fees toward charitable contributions and impact investment focused on health, wellness, and the built environment. IWBI was established by Delos in 2013 pursuant to a Clinton Global Initiative commitment to improve the way people live by developing spaces that enhance occupant health and quality of life by sharing the WELL Building Standard globally.
