Despite the establishment of computational fluid dynamics (CFD) as a tool for calculating the amount of wind-driven rain (WDR) falling onto building facades, very few efforts have been made towards the validation of CFD for this purpose. This article presents part of a detailed validation study that was conducted, supported by a new, high-resolution wind, rain and WDR database for a low-rise building. It will be shown that numerical simulation, if conducted with care, can provide quite accurate predictions of the amount of WDR impinging on the building facade and that the main discrepancies are due to a simplification of the upstream wind conditions in the numerical model.
