Abstract

The impact of the general layout of commercial streets and their orientation relative to prevailing wind direction on urban comfort due to natural ventilation is unknown. To study the natural airflow pattern in the commercial street mall, this research investigates the impact of different building layouts on airflow characteristics. To do this we conduct a parametric CFD simulation for 12 simulation cases, in which the commercial street layout changes to include secondary streets in four different cases. All cases are also subjected to three different wind directions. The study highlights that different wind orientations can significantly impact pedestrian comfort in shopping centres. Also, the presence of side streets can cause severe discomfort in cold climates while they could be utilized for comfort in temperate climates. The study is important for the purpose of architectural design where architects need to understand the implications of the different design layouts and wind angles on pedestrian comfort in commercial streets
