GENERIC MODELS FOR PEDESTRIAN-LEVEL WINDS IN BUILT-UP REGIONS

Wind conditions over streets in built-up cities were examined in a bou ndary-layer wind-tunnel model study. Presented in this paper are resul ts of wind speeds affected by a number of parameters such as the spati al density of street blocks, the building height over surroundings, th e relative location of buildings and the direction of approaching wind . Based on literature information and current findings, some generic m odels have been established with the empirical relations between wind conditions and building configurations. These models can be applied fo r the preliminary estimation of pedestrian-level wind environmental co nditions in built-up regions.
