BIM in Small–Scale Sustainable Design

The only book focused on BIM strategies for sustainable design in small– and medium–scaled architecture projects Though they are rarely addressed in the same book, building information modeling (BIM) and sustainable design have a lot in common: both are changing the way architects think about the buildings they design, and both have been considered more relevant to large projects than small. In this groundbreaking guide, François Lévy demonstrates that sustainable design has an even greater relative impact on small–building performance than large, and that BIM′s well–known efficiencies lower overall costs at any scale and can be easily applied to sustainable design. Using real–world examples, this practical desktop resource presents proven methods for using BIM to deal with such essential sustainability issues as natural ventilation for cooling, passive solar heating, and more. It places particular emphasis on using BIM–enabled quantitative analysis to evaluate design alternatives early in the design process, when problems can be corrected and architecture can be optimized easily and at little cost. In addition, BIM in Small–Scale Sustainable Design : Features case studies of eleven small–scale projects in which BIM methodologies were applied to sustainable design issues and problems Addresses critical topics, including site analysis and massing analysis, solar geometry and daylighting, passive heating and cooling, rainwater harvesting, onsite energy systems, materials and waste, and much more Surveys leading BIM applications and complementary software Includes a discussion on collaboration with consultants and other software users, such as energy modelers Complete with coverage of integrated design and other NAAB APR requirements, BIM in Small–Scale Sustainable Design is a must–have resource for architects, engineers, students, and construction professionals involved in sustainable design projects.

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.
