What Is the WELL Building Standard?

The WELL Building Standard is a performance-based certification system for buildings and organizations that focuses on human health and wellbeing. Developed by the International WELL Building Institute (IWBI) and launched in 2014, WELL evaluates how the built environment impacts the health, comfort, and productivity of the people who occupy it.

Where LEED focuses primarily on the environmental impact of buildings (energy use, water consumption, materials, site), WELL focuses on occupant impact. WELL and LEED are complementary — many projects pursue both certifications simultaneously — but they address different outcomes. A building can be LEED Platinum and have poor indoor air quality, inadequate lighting quality, or thermal discomfort. WELL addresses those gaps.<
