Abstract:
With the continuous growth of urban development and outdoor activities, residents are spending more time outdoors. The quality of outdoor environment and thermal comfort significantly impacts the physical and mental health of residents. However, the issue of winter outdoor thermal comfort has received limited attention. Using Chongqing Three Gorges Square in a hot summer and cold winter area as a case study, this research addresses the problem of winter outdoor thermal comfort. By conducting measurements of the winter thermal environment and administering thermal comfort questionnaires, the study utilizes the Rayman software to calculate the PET (physiological equivalent temperature) values as parameters for thermal comfort evaluation. A functional relationship between TCV (thermal comfort voting value), TSV (thermal sensation voting value) and PET is established. This relationship helps define the winter thermal comfort range for various outdoor environmental spaces. Additionally, a comprehensive winter comfort evaluation model suitable for hot summer and cold winter areas is proposed. The findings of this research serves as essential reference data for advancing the study of outdoor thermal comfort in regions characterized by hot summers and cold winters.
