This paper explores through professional case studies how design solutionsproduced by expert teams compares to those developed through systematicparametric analysis. While the expert intuition of either single designer or teamshelps to rapidly identify relevant aspects of the design problem and produceviable solutions, it has limitation to address multi-criteria design problems withconflicting objectives and searching for design alternatives. On the other hand,parametric analysis techniques in combination with data analysis methods helpsto construct and analyze large design spaces of potential design solutions. Forthe purpose of this study, the specifications of geometric features and materialproperties of the building envelopes proposed by the expert design teams definethe base line to measure the extent of the performance improvements of twotypically conflicting objectives: Daylight quality and energy consumption. Theresults show consistently significant performance improvement after systematicoptimization.
