RESUMO
Outdoor thermal comfort is significantly relevant to human's quality of life. Thus, it has been frequently studied by investigators. This study explored people's thermal responses to environments and the subjective factors that might affect thermal comforts with respect to two urban parks in Xindu, a satellite city in the Chengdu Plain (CDP). CDP is located at the southwest of China, which has a subtropical climate. The environment from each of the two parks was studied using current micrometeorology and hoped-for landscape changes (tree canopies, artificial canopies, non-canopying plants, and water surfaces); subjective factors included gender, age, body mass index, clothing isolation, and physical activities. It was found that canopies were the most preferred objective cooling elements, while individual thermal perceptions varied subjectively by age. The highest proportion of volunteers voted for tree canopies as their favourite thermal adjusting element. It was observed that those aged above 55 showed low thermal sensitivity. The remaining group's neutral temperatures (indicated by physiologically equivalent temperature, PET) were close, at approximately 25 °C. This study provides significant direction for future urban planning and landscape design.
