WELL, unlike most other systems, does not primarily assess the environmental impact of a building, but rather the health impact on the people in it: air quality, light, exercise, nutrition, mental health and community.
This is increasingly becoming an independent argument for companies competing for skilled workers, regardless of the building's climate footprint. Anyone who only treats WELL as an addition to an environmental certification that is already planned overlooks the fact that the criteria are different and require separate specialist planning, for example when it comes to air quality and lighting.
