An existing numerical technique for driving rain simulation based on Computational Fluid Dynamics is incorporated into a practical numerical method that allows estimating the spatial and temporal distribution of rain over land or on obstacles. The method is applied here to determine the driving rain load on the facade of a low-rise building for a series of spells. The numerical results are experimentally verified by comparison with full-scale measurements. It is shown that the numerical method can accurately estimate driving rain loads on buildings. A new averaging technique for climatic data to be used in driving rain estimation is proposed. Its performance is compared to that of currently used averaging techniques and shows to be good whereas the other averaging techniques can yield large errors.
