v1 of the WELL Building Standard focused on seven concepts: Air, Water, Nourishment, Light, Fitness, Comfort and Mind. When v2 was launched, the concepts were updated to reflect an even more holistic approach to human health and wellness. The resulting 10 concepts in WELL v2 are Air, Water, Nourishment, Light, Movement, Thermal Comfort, Sound, Materials, Mind, and Community. You might say, WELL is like a nutrition label for your building. It provides transparency on the quality of our built environment.
