ABSTRACT
This paper demonstrates that the homogenizability condition is not fulfilled for a macro-heterogeneous material like masonry. Homogenization can thus not be applied to reduce the size-problem of numerical simulation of moisture and heat transfer in masonry under atmospheric excitation. Instead, it will be verified that the internal redistribution of moisture – presumed to result from the spatial variation of the wind-driven rain exposure over a facade – is negligible, and that the hygrothermal response of a masonry facade can hence accurately be determined by ‘sampling’.
