Abstract: Though uncertainty and sensitivity analysis methods have been widely applied in the context of building energy modelling (BEM), only a limited amount of studies have investigated their performance at building stock scale. This paper aims at broadening the knowledge of global sensitivity analysis (GSA) application at building stock level by applying the Sobol’ SA at an internally developed building stock model. Further, the influence of the building stock size on the GSA model results will be addressed as well as the robustness of the GSA indices.
