Abstract
The theme involving the driving rain has been the subject of various studies that seek to contribute to the understanding of this phenomenon and its interaction with the buildings. In this sense, research discusses some aspects related to driving rain, such as the development and application of a methodology for quantifying wetting areas on models exposed to experimental driving rain, and the determination to the direction of the driving rain, in Porto Alegre city—Brazil, through the use of semi-empirical method, more specifically, a wind-driven rain relationship formula. The findings of this study demonstrate that the building facades oriented to the East/South quadrant have higher incidence level of driving rain, considering the Porto Alegre City-RS-Brazil. Furthermore, considering the application of the methodology, it was found, based on the images obtained in the experimental tests that both the building shape and the surroundings influence the degree of driving rain wetting on the models facades. In this way, the model with a square base and without surroundings showed the least amount of wet area when compared to the others.
