Shape, Space And Building Element: Development of a Conceptual Object Model for the Design Process

Abstract

The paper describes the first steps taken in the search for a central object model presenting all possible data, concepts and operations concerning the architectural design process. From the early design stage, an architectural model can be built on computer. A central object model of this process is essential: a model describing geometrical shapes, spaces, building elements and user activities, together with all the basic operations these entities can undertake. The model could provide the necessary information for the performance of tests to assist the designer (energy calculation, stability check, costs ...). Appropriate interfaces between the object model and existing software packages allow different actors in the design process to make use of the model's data. First, the conceptual model for CAAD in the design process is described. The second part deals with the methodology used for developing the object model: M.E.R. O.DE (Model-driven Entity-Relationship Object-oriented Development) proves to be a firm base to start our design. Finally, we present some aspects of the first prototype for such a central object model.
