Design of buildings has evitable importance from worldwide energy consumption point of view as
well as people’s quality of life point of view. Energia Design Synthesis (EDS) method considers both;
i.e. it is a unique technique ensuring de facto optimal buildings performing highest energy efficiency
while offering best comfort. As part of the method, first geometry generation rules complemented by
energy and climate-related rules are determined; then all feasible and potentially optimal building
combinations are generated, and other cases are excluded. As an extensive preparatory work, a large
number of complex dynamic thermal simulations (IDA ICE) were performed. Based on the simulation
data, some parameters were selected, that are considered to be of the highest importance from both
energy and comfort point of view. Nevertheless, based on the results of the simulations, a good practice
is to judge the most influential parameters and their dependencies. General sensitivity analysis can be
considered as a potential tool to support this process, i.e., it allows us to identify the most important
parameters in relation to the overall building performance. Here, for this case Sobol’ indices are applied,
which is a variance-based statistical technique for global sensitivity analysis. During the work individual
importance of the selected energy and comfort design variables as well as their joint effect is measured
and evaluated. Besides the building envelope determining variables of wall window ratio, orientation and
structures, diverse energy and comfort performance related design variables of the building geometry
were assessed and prepared for the analysis. The most relevant design variables affecting thermal and
visual comfort as well as energy efficiency were selected for future development of the optimization
method.
Keywords: sensitivity analysis, building simulation database, evaluation
