Multiyear hygrothermal performance simulation of historic building envelopes

The objective of this work is to quantify the effects short-term climate change with a multiyear (MY) approach on results heat and moisture transfer simulations an historic building located in Udine (Italy) evaluate if single year simulation could be representative obtained MY. hygrothermal performance related risk are evaluated for brick wall without insulation, MY 25 years three selected form software DELPHIN used damage indicators calculated using simplified methods (number days unfavourable conditions). Depending considered, have different studied wall. that use weather file allow obtain more accurate than one-year simulations, but effort time required interpretation not acceptable. It then shown choice crucial analysis considering one necessary damages mechanisms.
