Abstract: The pedestrian wind environment around a commercial center in Beijing was investigated in the wind tunnel. The pedestrian level wind velocity distributing could be attained by analyzing the result of test points arranged around the models. Based on the pedestrian level wind comfort criteria, which categorized different ranges of wind velocity as being appropriate for certain types of pedestrian activities and gave the corresponding acceptable frequencies of occurrence, the pedestrian wind environment was assessed quantitatively combined with the local wind climate statistic records. Some useful guide was provided to improve the comfortability in the potential uncomfortable or dangerous locations.

Key words: pedestrian wind environment, wind tunnel, pedestrian level wind comfort criteria
