Effects of building lift-up design on pedestrian wind environment

![CDATA[Building with a lift-up design may have a number of impacts on the pedestrian-level wind and thermal environment. Based upon the earlier wind tunnel tests that identified some building configurations that resulted in the lowest wind speed zones, a 3.5 meter-tall open ground floor was added to each of the three configurations, and scale models of the three designs were studied I a wind tunnel to assess their influences on airflow and ventilation around the buildings. Undesirable areas of low wind speed leading to poor air ventilation and at the other extreme, discomfort due to strong wind conditions are both identified in the results, and their practical implications are discussed.]]
