The built environment is a complex system, contradictory, and constantly changing. It embodies the complex, historical evolution of human knowledge, desires and technology. Computer simulations enable designers to better respond to the increasing complexity of cities, buildings, and the lives of the occupants within them. Simulations support specific disciplinary expertise and enable interdisciplinary collaboration. They can address many scales from the urban to the building component. Innovation in computer simulation questions disciplinary boundaries and derives knowledge from the convergence of different fields. The 8th annual Symposium on Simulation for Architecture and Urban Design (SimAUD) tackles the interdisciplinary aspects of the development and use of simulations to measure, predict, assess, comprehend and manage the performances of buildings and cities, in regard to their technical and nontechnical requirements.@en
