Abstract

Rapid urbanization and overpopulation, along with a lack of green space, led to an increase in air temperature, lowering the rate of thermal comfort in dense urban areas, decreasing air quality, and increasing the urban heat island (UHI) phenomenon, particularly in existing cities. As a result, the research aims to reduce the UHI effect and improve the thermal performance of existing Egyptian cities by adopting green infrastructure (GI) principles and demonstrating their effectiveness on the UHI phenomenon. This research concentrates on the UHI phenomenon as one of the environmental issues facing urbanization and includes a review of green infrastructure (GI) as one of its mitigation strategies. In addition to analysing different existing urban neighbourhoods that used green infrastructure (GI) in their urban design to evaluate its effectiveness on urban thermal performance, The research also includes an applied study for one of the areas of the city of Mahalla Al-Kubra, Gharbia Governorate, Egypt, in which different green infrastructure (GI) scenarios are studied and analysed using the environmental simulation program ENVI-met to identify their effect on thermal performance by analysing the air temperature, mean radiant temperature (MRT) and the predicted mean vote (PMV), which affect the UHI phenomenon.
