This websites explains the combination of factors that need to be avoided for whistles prevention. A beautiful new building... and then it turns out to whistle in windy weather. A horrendous scenario for the area and the designer. With the current (Computational Fluid Dynamics) simulations it's hardly impossible to estimate the 'whistle risk' beforehand, see background information.

For me as a Building Physicist, this was the trigger to examine known whistling buildings and objects and compare this with the current fluid dynamic theory. There appear 4 principles that all need to be fulfilled to create a whistle, or in this case, to be avoided.

Are you in a design process? Is a whistle currently disturbing you? Like to discuss different ways to reform the whistle, feel free to contact me.
