The early design process has the most salient design decisions for architects. It is crucial to observe the impact of these design decisions in terms of performance-based design. However, because of the large amount of variance of the performance criteria in the early design parameters, the decision-making is highly arduous. The current study proposes a method to quantify output uncertainty and presents the relationship between independent and dependent variables for providing insight into the decisionmaking process. The energy simulations for hypothetical office building based on TS-825 requirements were executed with cooling and heating demand (kWh/m2 -year) outputs for two different regions, i.e., Erzurum as a cold climate and Izmir as a hot-humid climate. Researchers computed the input parameters' impact on building performance with quasi-random statistical sampling and filtering techniques. Respectively, ineffective parameters eliminated with factor fixing and factor prioritization (i.e., first-order) was realized to sort the most effective parameters with Morris Local Sensitivity Analysis. The interaction (i.e., second-order) between independent variables was analyzed using Global Sensitivity Analysis of Sobol'. The output weighting process was applied for rating each result combining the performance based on output variablesfor the factor mapping. It is the presentation of 100 best solutions in the aspect of the effective range of the input parameters for the mostsignificant reduction in the variance of the output variables. The results were presented with Parallel Coordinate Plot (PCP) for each climate as a comparison. Consequently, the study showed how climate conditions are essential for building energy demand, and design options could be analyzed based on the impact of design decisions.
