This paper presents a model of an architectural design process for multi-performances which incorporates a constructivist approach of multi-criteria decision support. This approach seeks to reconcile the value system of decision makers, as it believes that they do not have the same goals. Thus, the aim is to reach a space of consensus among decision makers (in the case of the design, among experts/designers). This space of consensus must aggregate multiple views of reality arising from each participant. We started from the hypothesis that the incorporation of such an approach helps to reconcile conflicting goals of the project and, therefore, for collaboration among experts since the early stages of design. The proposed model is result of a research based on a Design Science Research approach. This methodological approach suggests the proposition of an artifact to solve a practical problem. In this case, the practical problem is the compatibility of multiple performance dimensions in the project. The proposed artifact is the model of an architectural design process for multi-performances. The application and testing of the model occurred through a didactic experiment. It is expected, through this research, a model of design process that systematizes the participation of experts and promotes collaboration in order to reach compatible goals of different dimensions of performance in a design solution.
