Analyzing the Impact of Urban Planning and Building Typologies in Urban Heat Island Mitigation

Urban and building typologies have a serious impact on the urban climate determine at large magnitude of overheating heat island intensity. The present study aims to analyze various city planning characteristics mitigation island. effect height, street width, aspect ratio, built area orientation, dimensions open spaces distribution ambient surface temperature in is analyzed using Sydney Metropolitan Area as case for both unmitigated mitigated scenarios. Fourteen precincts are developed simulated ENVI-met simulation tool. temperature, wind speed extracted. parameter ‘Gradient Temperature Decrease along Precinct Axis’ (GTD) introduced cooling potential precincts. In precincts, GTD ranges between 0.01 K/m 0.004 K/m. non-mitigated 0.0093 0.0024 A strong correlation observed all with without mitigation, their corresponding average (Height buildings Width streets). higher ratio precinct, lower potential. It also that Built Ratio contribution measures.
