Although several methods for assesing characteristics of environmental winds around a high-rise building have been introduced, these methods seem to be aiming at relatively flat and low built-up areas. Since heights of buildings is actual urban areas are various, it is not appropreate to apply these methods to practical cases. In this paper, an experimental equation to estimate wind velocity around a high-rise building in an urban area with buildings of a variety of heights is presented, and the applicability of the equation is studied by witd-tunnel tests using a model of an existing urban area. As the result, it is learned that calculated values obtained from the proposed equation are in good agreement with those from experimental and that the equation can be put to practical use.
