(Background/Question/Methods ) Urban heat islands caused by urban development may cause severe illnesses and affect people’s outdoor activities. In an outdoor environment, a person's thermal comfort varies with dynamic weather conditions and thermoregulatory system. However, most outdoor thermal comfort models in the literature have been developed based on steady-state conditions or data for a specific point in time. Therefore, an accurate predictive model is required to evaluate the dynamic thermal comfort considering the accumulated heat stress according to the distance in the outdoor space. In order to develop a dynamic thermal comfort model, this study expanded the two-node model by measuring the response of human subjects from the south of Korea, outdoor environment parameters, and physiological factors for experimenters. We then analyze the performance of the dynamic thermal comfort model in the outdoor environment and the critical parameters affecting thermal comfort with respect to climate and Physiological factors. It was concluded that the model proposed in this study adequately reproduced the dynamic thermal environment in an outdoor environment. The findings should provide valuable insights for informing urban planning designers on formulating effective strategies to improve the thermal environments in the outdoor urban areas in the temperate climate zone.
