A set of applications of global sensitivity analysis to building thermal modeling is discussed. The aim is to demonstrate the interest of such tools for model analysis and to encourage their use. Indeed, since the last ten years important improvements have been made in the field of sensitivity analysis and especially in computational methods based on the analyse of variance (ANOVA). Yet, their use in the field of building performance modelling is uncommon. After recalling the concept of ANOVA-based sensitivity analysis and the associated sensitivity indices, we describe some computational methods to compute the global sensitivity indices of model input factors. The emphasis is on the methodology that is computationally cheapest but provides more information. For illustration, they are applied to an actual test-cell thermal model.
