Urbanization process has dramatically influenced urban climate and environment. In the urban planning and design practice, there are several important parameters such as sky view factor, floor area ratio, site coverage ratio and building stories. These parameters can determine the urban morphology. This study shows the impact of urban morphology parameters on urban microclimate. It aims at provide suitable ranges of parameters which are beneficial for the thermal comfort of urban pedestrians. As a result, recommendations are given for government agency and urban planners in the urban design process.
