Abstract
At present, few computational methods exist that support architect in predicting how their design will be used and experience after its construction. The research described here aims at establishing a new approach for the computational simulation of building occupancy, focused on a clear definition of use scenarios as specific structures of active entities called Events. They allow the formalization of parts of building use process in terms of Actors involved, Activities performed and Space where these events takes place. This modeling framework is functional to simulation environment, where scripted building use process is effectively computed and simulated..
