We spend 90% of our lives indoors, yet we underestimate how much the interior of buildings influences thoughts, feelings, and behavior. This course will examine how the incorporation of natural elements like sunlight and plants indoors improves mental health. Through tours of innovative “green” buildings, students will learn how their homes, schools, and workplaces can be designed to enhance human flourishing. At the conclusion of the course, students will be empowered to advocate for changes in the built environment.
