Learning how to model and simulate dynamical systems such as a building does not have to be restricted to specialists who have learned the physics, applied mathematics, and engineering necessary for the task. Modern software tools allow for a new approach to modeling which makes it accessible to a much wider group of scientists, eng neers, and architects. This paper presents an integrated modular method for training students in the methodoIogy of modeling and simulation. Students can leave the process at different levels allowing them to either appreciate the content of models of dynamical systems and intelligently use existing models; to be able to quickly build simple models themselves for testing ideas; or to become full-fledged modelers.
