A building standard that focuses on best practices in design and construction that contribute to the health and wellness in building occupants. The WELL BUILDING STANDARD was created by the INTERNATIONAL WELL BUILDING INSTITUTE (IWBI), a public benefit corporation founded in 2013. The standard is administered by GREEN BUSINESS CERTIFICATION INC (GBCI). The standard itself was launched in October 2014 following six years of research and development which explored the health and wellbeing impacts that buildings have on their occupants. It integrated scientific and medical research and literature on environmental health, behavioural factors, health outcomes and demographic risk factors that affect health with best practices in building design, construction, and management. A second version of the WELL standard was launched in 2020 and incorporates ten concepts including: air, water, nourishment, light, movement, thermal comfort, sound, materials, mind, and community.
