Communicating performance assessments of intermediate building design states

Collaborative building engineering is a team effort in which many elements have to be combined into a unified structure. The aims of the architect, the engineer and all the other players have to merge into a seamless design process. This paper deals with the exchange of information among the design team members, and introduces methods that enhance a particular subset of the exchanged information, i.e. the information related to performance of intermediate designs. A new technique is introduced to control the invocation of performance assessments as the design evolves, based on the availability and level of uncertainty of input data.
