The aerodynamic characteristics of windbreaks, resulting in empirical design rules

Abstract This paper presents studies of windbreaks as an aid to town planning. Pedestrian comfort is quantified in terms of the sizes of areas having a specified wind-speed reduction, resulting from the use of windbreaks. The paper is divided into three main parts. The first deals with single windbreaks, and the second with combinations of windbreaks. In the third part, spectral methods are used to verify that windbreaks do not produce fluctuations predominantly at any particular frequency, and hence cannot be “tuned” to provide enhanced comfort.
