    Abstract

    ![CDATA[This study focuses on the pedestrian-level wind environment and pollutant dispersion from an upstream or downstream line source representing vehicular emission from a line of stopped buses. Buildings with a lift-up design may have a number of impacts on the pedestrian-level wind and pollutant dispersion environment. Three building configurations that resulted in the lowest wind speed zones were identified from a previous study. A 3.5 meter high open ground floor was added to each of the three configurations, and scale models of the three designs were studied in a wind tunnel to assess their influences on airflow, ventilation and pollutant dispersion around the buildings. Undesirable areas of low wind speed and excessively high wind at the other extreme, pollutant dispersions from the respective line sources upstream and downstream were compared, and the practical implications to the wind and thermal comfort and pollutant dispersions are discussed.]]
