Research Project: Architectural Daylighting

The particular area of architectural design we explore is daylighting: the use of windows and reflective surfaces to allow natural light from the sun and sky to provide effective and interesting internal illumination. Appropriate daylighting strategies can reduce energy consumption not only for lighting, but also for heating and cooling through solar gain management, which altogether account for half of a building's energy requirements and about 20% of total U.S. energy consumption. Our focus is on creating innovative tools that allow designers to explore alternative designs and new technologies for improving the sustainability of their buildings.
