Welcome to WELL

At the International WELL Building Institute (IWBI), we’re committed to transforming health and well-being with our people-first approach to buildings, organizations and communities. Since the launch of our WELL Building Standard (WELL) in 2014, 2,000+ companies, including over 100 of the Fortune 500, have adopted WELL as an evidence-based roadmap for scaling health across their organization.
