Abstract:

Flow patterns at ground level in groups of buildings result from the complex interaction between the wind (impact, average speed distribution with height, and turbulance) and the buildings themselves (shapes, sizes, arrangements, etc). The increase in the number of very tall structures and the more or less arbitrary, with respect to wind, placing of large structures have frequently demonstrated the lack of adaptation of the structural environment to wind phenomena. Manifestation at ground level, such as zones of high speeds or eddies, make the approach to buildings uncomfortable (sometimes even dangerous) for the pedestrian. Elimination of these problems requires better knowledge of air flows around structures and formulation of practical plans that the architect or city planner can use in designing larger structural units. This report summarizes work carried out at the CSTB institute in Nantes in 1973 and 1974 and gives the main results of the study. A guide is included which furnishes simple rules or practical advice that can be used by architects and city planners.
