Living Building Challenge
WELL Building Standard
Leadership in Energy and Environmental Design (LEED) is a building certification program created by the U.S. Green Building Council (USGBC) and is defined as providing “a framework for healthy, efficient, carbon and cost-saving green buildings. LEED certification is a globally recognized symbol of sustainability achievement and leadership.¹” Lighting can contribute to the Energy and Atmosphere (EA), Sustainable Sites (SS), Environmental Quality (EQ) and Materials Resource (MR) sections².

How Does Lighting Contribute?
“WELL is a performance-based system for measuring, certifying, and monitoring features of the built environment that impact human health and well-being, through air, water, nourishment, light, fitness, comfort and mind. WELL is grounded in a body of medical research that explores the connection between the buildings where we spend more than 90 percent of our time, and the health and wellness impacts on us as occupants. WELL Certified™ spaces can help create a built environment that improves the nutrition, fitness, mood, sleep patterns and performance of its occupants.” Lighting is one of 10 “Concepts” or categories in the WELL Building Standard. The Light concept promotes exposure to light and aims to create lighting environments that promote visual, mental, and biological health³." Lighting can also contribute points in the materials transparency concept.

“The Living Building Challenge is an attempt to dramatically raise the bar from a paradigm of doing less harm to one in which we view our role as a steward and co-creator of a true Living Future. The Challenge defines the most advanced measure of sustainability in the built environment today and acts to rapidly diminish the gap between current limits and the end-game positive solutions we seek⁴.”
