How can well-being attributes, impacts and value be incorporated into architecture, design, buildings and construction? Can well-being impacts be measured in terms of the mental, physical, emotional, and spiritual well-being of people who live and work in these new well-being-by-design buildings and homes? Can well-being impacts translate into greater productivity at work, a greater feeling of meaningfulness and flow at work and improved financial performance of enterprises? I believe well-being is the new frontier in building standards. Measuring well-being, however, must use both objective metrics such as the new WELL building standards/criterion and also subjective well-being measures that come from well-being surveys of employees, tenants or occupants and customers who experience the well-being attributes of built spaces.
