The built environment directly impacts human health and well-being, yet most green certification systems prioritize energy efficiency over occupant health. The WELL Building Standard (WELL), launched in 2014, addresses this gap by focusing on the health and comfort of building users. Despite its growing importance, limited academic research systematically examines its global implementation. This study will fill this research gap by analyzing 1559 WELL-certified projects worldwide using the WELL database. The results reveal that 50% of certifications are concentrated in China and the United States, while regions such as Africa and Latin America show minimal adoption. Most projects are office buildings (83%), with fewer in education, healthcare and residential sectors. Additionally, most certified projects have achieved Gold or Platinum levels, and there has been a notable increase in certifications since the COVID-19 pandemic. By identifying geographic and typological disparities, this research provides a global overview of WELL adoption and offers insights for practitioners and policymakers seeking to promote healthfocused building practices.
