This study investigates how different vegetation species and intensities affect pedestrian comfort in a hot and humid city. The study was conducted in three stages: Firstly, five different scenarios (unvegetated, sparse tree crown-low density, sparse tree crown-high density, dense tree crown-high density and dense tree crown-low density) were investigated to enhance pedestrians’ thermal comfort. Secondly, the ENVI-met model was used to evaluate the microclimatic changes for these different vegetation scenarios in pedestrian line. Finally, the results of the study suggest the need for further investigation to study whether the thermal mass effect of the plants increases the simulation accuracy regarding outdoor thermal comfort.
