In this course, students focus on the massing and orientation of architectural form and fenestration to integrate daylight with interior space and programming. Electric lighting is addressed as a secondary complement to the primary focus of natural light. Particular attention is given to the relationship between diurnal patterns, qualitative aspects of habitation, energy conservation, solar heat gain, and illuminance requirements. Design aspirations are rigorously investigated through analog and digital analysis tools in order for students to better understand the relationship between aesthetics and performance.
