What is the difference between the WELL Building Standard® and LEED certification?

Where LEED is concerned with building sustainability and operations,, the WELL Building Standard ® focuses on the wellbeing of the building’s occupants themselves, the people. It starts with the LEED indoor air quality standard, then adds ratings for factors affecting people: natural light, access to windows, physical space and planning, comfort, and even access to nutrition. The WELL Building Standard tells us about the impact of a building on human beings.
