Virtual prototyping for open building design

This paper re-visits the basic premises of open building: designing for change as well as for stability, including the users in the design decision-making processes, and disentangling the building systems into the levels and allowing replacement; then, addresses the limitations of conventional design media in terms of the capabilities to support these aims. It is discussed that the design media should be predictive, dynamic, and interactive. Virtual prototyping as an enabling technology is reviewed and proposals are made for the future use of this technology for open building design.
