THE INFLUENCE OF THE URBAN DESIGN ON THE AIR EXCHANGE IN CITIES. SELECTED PROBLEMS IN POLISH REALITY
Abstract
The progress of the architecture and urbanism raises problems requiring interdisciplinary research conducted with the use of advanced experimental techniques and computer simulation. The fields of this research include aerodynamics, especially in intensively developed area of Environmental Wind Engineering (EWE). Aerodynamic phenomena occurring around buildings have a significant impact on the quality of the climate in the cities. This paper deals with the issue of dependence of air exchange in urban spaces on the building forms used in them and on relative position of these buildings. The author considered this issue in two different scales in the scale of the city as a whole and the scale of urban development. The conclusions are focused on the problems of the densification of the urban development of Polish cities, which, if not controlled enough, may contribute to reducing the air exchange.
