Daylighting is inherent in architectural design and is one of the main drivers of a building’s technical performance and its resulting human comfort and health. Students in the Fall 2009 Daylighting class taught by Marilyne Andersen, Associate Professor at MIT, worked in interdisciplinary teams to analyze designated portions of the second floor extension to the swissnex Boston building in Cambridge MA. With the aim of developing integrated solutions for façades on every side of the building, they focused on issues of glare, illumination, overheating, the ensuing energy requirements and the visual interest of the spaces. This publication documents the creative solutions that the students developed to answer this multi-faceted problem using models, data analyses, and simulations. Their work illustrates how challenging and inspiring it can be to answer a seemingly simple question, “What is good daylighting?”.
