The International Well Building Institute is based is California. It has developed a set of standards to ensure that a level of health and well-being is enjoyed by building occupants where these standards are followed.
The standards are tied into medical research, evidentially backing up the design decisions. WELL call their work the evolution of sustainability, and I agree, putting the person and their well-being at the centre of the project creates a filter for all decision making that will lead to the healthy and sustainable choice. The WELL system ensures that Air, Water, Light, Comfort, Fitness, Nutrition and the Intellect are all reinforced through design, and not compromised.
Gaining this accreditation took a few months of focused study which will inform all of my forthcoming designs. It also enables me to assist in the management of larger projects that may wish to follow these principles and even seek Project certification in WELL.
