Optimization of urban morphology to enhance outdoor thermal comfort: A microclimate analysis

Climate-aware urban environments pose a significant imperative to obtain thermally comfortable outdoor areas. The present study addresses the optimization of urban block morphology in Guelma City, Algeria, to enhance thermal performance in a semi-arid climate. Using in-situ measurements and simulation generated by the ENVI-met simple forcing scheme, the impact  f urban morphology on the variation of outdoor comfort factors, including air temperature, relative humidity, and wind speed  arameters, is identified. The conducted investigation illustrates building configuration, orientation, and street canyon geometry as key indices affecting thermal comfort. Results pointed out urban green cover’s role in mitigating heat island effects. In conclusion, the study underscored the significance of an interconnected analysis of urban patterns and heir correlated influence on urban microclimate for achieving thermally comfortable outdoor environments.
