The course deals with BIM issues with an emphasis on the application of Building Service-Systems, TZB, to digital building models. In the exercise, a model will be developed on available software (student licenses). The model will include both 3D element modelling and product demonstration from specific suppliers of building or technical components. Students will learn how to create and edit a spatial model, including all installations, from which they can easily get 2D documentation, as well as realistic visualizations.
