Modelling Wind-Driven Rain Impact on Plastered Facades Using Direct Measurements, EN ISO 15927-3 Calculations and CFD
Wind-driven rain (WDR) is a major moisture source for exterior walls and a key factor in the hygrothermal performance of unventilated facade systems, particularly those relying on moisture buffering. Accurate representation of WDR in hygrothermal modelling is essential, yet most approaches use vertical rain and wind da...
