Roof overhangs are a common feature that can be used to protect the building façade from wind-driven rain (WDR) as field measurements and CFD modelling have shown. However, the quantitative evaluation of the effectiveness of overhangs in protecting the building façade requires further investigation. A six-storey mid-rise building with a flat roof located in Vancouver, British Columbia, Canada has been selected for the experimental study. The study involves the analysis of the spatial

This paper presents the experimental setup, preliminary result analysis including the spatial variation of catch ratios on the building façade, and the performance assessment of a 1.2 m overhang under two rain events.
