Developing Heat Mitigation Strategies in the Urban Environment of Sydney, Australia

Heat island effects raise the ambient air temperature in metropolitan areas by 4–5 degrees Celsius and can reach 10 at their maximum. This phenomenon magnifies cities’ energy difficulties while reducing comfort. Mitigation strategies have been developed recommended to deal with issue. Methods increase albedo utilisation of vegetation appear be most promising, a reasonably high heat reduction capacity. paper examines mitigation techniques effectiveness under Sydney’s climate conditions compares strategies. We implement two perspectives, namely urban greening (green roofs, green pavements) (street, roof), characterise surface structures, Envi-met software is employed for our simulation method. show cooling potential 4.1 °C along this precinct during heatwave period. Scenarios that high-albedo material on road, pavements rooftops full maximum potential. The higher predicted peak temperature, up 1.18 °C, having no or little impact minimum temperature. outdoor thermal comfort based PMV indices varies between −0.33 scenario seven large layout 3. However, presents more acceptable comfort, but layouts are hot condition.
