BIM in Small-Scale Sustainable Design

François Lévy, AIA, AIAA,is a registered Texas architect and researcher. He holds an MArch and an MS in architectural engineering from The University of Texas at Austin, where he has been lecturing since 1998. Mr. Lévy has been practicing architecture since 1993, and established his own firm in 1997. His architectural projects have attracted regional and national press, including Dwell magazine and HGTV. In addition to leading CAD and BIM seminars to professionals, his areas of research interest are sustainable architecture, cooling through passive ventilation, and space architecture.
