Hygrothermal simulations comparative study: Assessment of different materials using WUFI and DELPHIN software

Abstract

In building simulations for hydrothermal evaluation there are many uncertainties related to the materials properties, to the initial and boundary conditions and to the calculation methods used for the models. The aim of this paper is to perform a series of hydrothermal simulation with two disseminated solvers: WUFI Pro 4.2 and DELPHIN (Version 5), in order to compare their results, specify the differences between them and identify both their limitation and potentialities. The simulations consider the EN 15026; diverse materials like brick, concrete and plaster, different simulation times (60-days and 2-years) and steady climatic conditions or real climatic data from Munich. Obtained results from the two software programs are very close.
