The Pedestrian Level Wind Environment Test is performed to evaluate the comfort and safety of pedestrians near the building. When a tall building is built, the wind flow pattern around the structure creates unexpected currents with varying speeds, which can significantly affect the pedestrian experience at ground level. These effects can lead to discomfort, making walking difficult, or in extreme cases, pose safety hazards due to strong gusts.
Generally, the pedestrian wind environment is assessed using wind speed ratios and the probabilities of specific wind speeds and directions occurring near the target area. This evaluation helps identify areas where wind conditions may exceed acceptable comfort or safety thresholds, allowing for potential design modifications. The test considers multiple factors, including seasonal variations, surrounding structures, and localized turbulence effects, to ensure accurate results.
