||The validation of integrated CAD in building engineering design
||The need and the urgency to develop integrated CAD software for building design are well established in industry and academia alike. The means and the approach to achieve this objective are however not soclear and do not meet with general agreement. Even the final product itself - integrated CAD - has different meanings for different people.Like other research groups in building studies, we have developed a number of integrated building design systems in the last few years thateffectively combine different activities and types of expertise in a unified approach. For these successful research initiatives, the fundamental issue of validation remains a very difficult one to answer properly. On the one hand, reference cases do not exist to benchmark the operation of an integrated system, as in the case of experimental or empirical processes. On the other hand, no clear guidelines have emergedyet from commercial software developers in the construction industry that claim to have achieved 'integrated CAD' as soon as some form of file transfer exists between an application software and a CAD package.From the study of some integrated CAD systems for building design recently developed in industry and at the CBS, this paper will attempt tocircumscribe the main aspects of the validation issue, e.g. what are the characteristics of integrated CAD ? what kind of performance is expected from such systems ? are current systems delivering what building design practitioners need ?
