Construction Sequence Based Influence of High-rise Urban Development on Pedestrian Wind Comfort in Lujiazui, Shanghai

Abstract

Abstract. Pedestrian wind comfort is becoming an important factor of evaluating the urban quality, because it influences the urban micro-climate, heat island effect, building energy consumption and the vitality of the city, especially in high-density and high-rise areas. This paper has selected one typical district -Lujiazui Central Business District (CBD), with a large number of skyscrapers, for analyzing the relationship among urban physical data, construction sequence and outdoor wind environment. Firstly, Computational Fluid Dynamics (CFD) has been applied to simulate the outdoor natural ventilation in different development stages in Lujiazui district. Then, pedestrian wind comfort will be evaluated, which integrated with the fourth dimension (buildings' construction completion time) for regression analysis. This research results will provide the government and designers feasible urban design recommendation for establishing sustainable outdoor urban environment.
