Thermal Comfort in Pedestrian Spaces of Mountain Cities in Humid and Cold Environments

[en] This study aimed to explore the microclimate and outdoor thermalcomfort characteristics of pedestrian spaces in mountain cities under humid andcold conditions. It focused on rainy and cloudy winter days in a typical moun-tain city (Chongqing), employing a combination of onsite thermal environmentmeasurements and survey questionnaires. The research analyzed the Thermal Sen-sation Votes (TSV), thermal comfort evaluation indices (Universal Thermal Cli-mate Index—UTCI, Physiological Equivalent Temperature—PET), and thermalenvironment parameters at representative sites. The findings revealed that firstly,outdoor thermal comfort and perception on cloudy winter days was minimallyinfluenced by the microclimate. In contrast, on rainy winter days, it was sig-nificantly impacted by black globe temperature and wind speed. Secondly, thecorrelation between PET and Mean Thermal Sensation Vote (MTSV) was foundto be higher than that between UTCI and MTSV, indicating that PET might bemore aligned with the local climate and pedestrian activities. Lastly, the studydetermined the neutral PET range for different weather conditions in the area andcompared it with existing research to identify discrepancies. This paper offers areference for the neutral thermal comfort range in pedestrian spaces in regionswith hot summers and cold winters under humid and cold winter climates, pro-viding theoretical support for urban planning and design, with an emphasis on theresults being presented in the past tense to reflect completed experiments.
