There is an increasing number of cases of building exterior materials that contribute to improving environmental performance such as louvers and vertical pins in recently constructed office buildings. Since these exterior materials are composed of relatively fine installation pitches or have a complex cross-sectional shape, noise (hereinafter referred to as wind noise) may be generated inside and outside the building when wind acts. It is common to require a preliminary review for the purpose of preventing wind noise in advance. As a preliminary review method for wind noise, a prototype test sample for the exterior material of the target building is installed in the wind tunnel, and the occurrence of wind noise is checked by applying winds of various wind directions and wind speeds. Punching metal is widely used as an exterior material for urban buildings. In the case of punching metal, it is known that wind noise occurs when strong winds occur. In this study, a wind tunnel test was conducted on the wind noise characteristics according to the thickness and hole size of the punching metal. As a result of the wind tunnel test, it was confirmed that the wind noise generated from the exterior of the punching metal is determined by the diameter of the hole, the thickness of the plate, and the wind speed.
