Contrasting the Capabilities of Three Different Sensitivity Analysis Methods for Building Energy Model-based Investigations

Steffen Petersen, Martin Heine Kristensen

Abstract: When using building energy models (BEM) for building design, it is often valuable to conduct a sensitivity analysis (SA) to help designers to focus their efforts on design variables that drive the majority of the building performance indicators such as energy use. In this study, three different SA methods (Local, Morris and Sobol’) were applied to two different BEMs (hourly dynamic and monthly quasi-steady-state) for SA analysis in two different stages of the building design process. The finding is that the choice of appropriate SA method depends on the purpose of the SA; whether it is a screening of equally probable design options, or a more thorough quantification and ranking of parameter uncertainty.
