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.
