Abstract In the last decades, Parametric design has developed greatly and its goals have expanded to include environmental, social and other goals. This research deals with the possibility of parametric urbanism in optimising outdoor thermal comfort in hot climates, in the regard of climate change and the urban expansion that Egypt is currently witnessing. This is through a specific methodology that was divided into three main parts. The first is the theoretical part to review the development of parametric architecture and urbanism, the different approaches of parametric urbanism, and the most used tools in the parametric design and environmental simulation. The analytical part aims to analyse the microclimatic factors affecting the outdoor thermal comfort, the most appropriate optimisation strategy in the hot climate, the most suitable approach and index in assessing outdoor thermal comfort. Additionally, it also analyses the urban geometry indicators influencing outdoor thermal comfort, the geometrical ranges in the Egyptian codes, and the most used urban pattern in the residential areas of Greater Cairo. The Final part is the practical study, it presents the detailed steps in modelling the case study to assess the outdoor thermal comfort in the hot climate. It was found that Grasshopper, Ladybug can successfully be used in modelling and simulating the outdoor thermal comfort. The outdoor thermal comfort in the hot climates can be optimised by the shading strategies. The sky view factor, floor area ratio, are the most influential urban indicator affecting outdoor thermal comfort in the hot climate, as the outdoor thermal comfort can be significantly optimized by decreasing sky view factor and increasing the floor area ratio, which can be achieved by increasing surrounding buildings’ heights. Moreover, the east and west sides of the urban space are the strongest in impact on outdoor thermal comfort in summer as concluded from the simulation. |
