Abstract A facade element of a hospital building was tested in the wind tunnel of the Federal Research Institute in Vienna. This element consisted of six main parts: the window, the window frame, the inspection walkway in front of the window, the console, the handrail of the walkway and the sunshades. The last three parts were believed to be especially susceptible to wind-induced vibrations. An original facade element was mounted in the test section of the MTI wind tunnel. The natural frequencies of the main parts were determined and the wind-induced vibrations were measured at wind velocities between 10 and 110 km/h. The angle of attack was changed between 0 and 90 degrees according to the flow around the building. The most remarkable result was the detection of a strong wind-induced acoustic radiation at narrow limited velocity ranges around 55 and 110 km/h. This sound was produced by the grid of the walkway. The other vibration phenomena were of minor importance. The design of the grid was changed as a result of the wind-tunnel tests. The facade elements were installed one year ago and there have been no complaints since then about excessive noise on windy days.
