Susan Ubbelohde is Associate Dean for Faculty Affairs and Professor of Architecture. Professor Ubbelohde and her partner George Loisos lead an office of unconventional practice, bringing research methods and physical and computer modeling to a wide range of architectural design solutions. The firm has pioneered new methods of energy conservation, production and analysis; lighting and daylighting design and analysis; natural ventilation analysis; concept design and fabrication of light emitting and controlling elements including light sculptures. Most projects are collaborations with other firms where L+U contributes tools and processes to reveal aspects of building performance. The firm works closely with University researchers, LBNL and other research institutions to bring the most sophisticated and appropriate technology to the practice of architecture.
