Abstract

Three different calculation models for wind-driven rain (WDR) are compared: the semi-empirical model in the ISO standard for WDR (ISO), the semi-empirical model by Straube and Burnett (SB) and the CFD model by Choi, extended by Blocken and Carmeliet. This paper builds further on the comparison of these models for idealized building configurations and fixed wind and rain conditions in [Blocken et al., 2010. Comparison of calculation models for winddriven rain deposition on building facades, Atmospheric Environment 44(14): 1714-1725]. In the present paper, these models are applied to a high-rise monumental tower building, for a transient rain event, and the model results are compared with full-scale measurements. The agreement between the CFD results and the measurements is quite good at the upper part of the facade, while the ISO and SB model show large discrepancies at these facade positions.
