The concept of biophilia—first coined by American biologist Edward O. Wilson in the 1980s, theorizes that humans have a biological need to connect with nature on physical, mental, and social levels, and that this connection affects our personal well-being, productivity, and societal relationships. The concept is easy enough to understand on a micro level. We are all inspired by nature in some way, and respond positively to fresh air, landscape views, and natural light. But on the macro level—as a design concept that can shape the entire built environment—biophilia is somewhat more complex. An offshoot of the sustainability movement, biophilic design seeks to integrate nature and structure by focusing on bringing nature into indoor space, incorporating materials and patterns that evoke nature, and planning open space configurations that allow for expansive views.
