Pedestrian wind comfort near a super-tall building with various configurations in an urban-like setting

Pedestrian-Level Urban Wind Flow Enhancement with Wind Catchers

Dense urban areas restrict air movement, causing airflow in urban street canyons to be much lower than the flow above buildings. Boosting near-ground wind speed can enhance thermal comfort in warm climates by increasing skin convective heat transfer. We explored the potential of a wind catcher to direct atmospheric wind into urban street canyons. We arranged scaled-down models of buildings with...

Wind Interference Effect on Tall Building

When a building is located in an urban area, it is exposed to a wind of different characteristics then wind over an open terrain. This is development of turbulent wake region behind an upstream building. The interaction with upstream building can produce significant changes in the response of the tall building. Here, in this paper, an attempt has been made to study wind induced interference eff...

Child pedestrian injury in an urban setting: descriptive epidemiology.

OBJECTIVE To describe the epidemiology of pedestrian injuries to children and adolescents (ages <20 years) in an urban setting, providing analyses of environmental and pedestrian variables. METHODS Anonymous data were obtained for all motor vehicle crashes occurring in New York City over a seven-year period (1991-1997). RESULTS Among 693,283 crashes, 97,245 resulted in injuries to 100,261 p...

Pedestrian wind comfort: Feasibility study of criteria homogenisation

CFD simulation for pedestrian wind comfort and wind safety in urban areas: General decision framework and case study for the Eindhoven University campus

Wind comfort and wind safety for pedestrians are important requirements in urban areas. Many city authorities request studies of pedestrian wind comfort and wind safety for new buildings and new urban areas. These studies involve combining statistical meteorological data, aerodynamic information and criteria for wind comfort and wind safety. Detailed aerodynamic information can be obtained usin...
