This seminar course will support students in integrating daylight concepts into their ongoing studio projects. With an emphasis on the perceptual, qualitative, and emotional aspects of daylight, the ultimate objective is to achieve an awareness of how daylight both shapes and is shaped by architecture. To do this, we will adopt a ‘design decision support approach’ that embeds daylight within the design process. In combination with theoretical inputs, daylight performance evaluation will be mostly driven by “why” questions, encouraging deeper conversations in the form of discussions and desk critiques. To support the ideas generated by the design decisions, evaluation tools—including simulation-based analyses, heuristics, and scale modeling—may be employed depending both on the previously acquired knowledge of the students and the specific needs of their studio projects. The work will be assessed primarily based on each student’s learning journey, rather than the final daylight performance of their projects.
