“…The most comfortable, preferred PET in winter for PBWh was 30.1 • C, while for PCfa it was 27.6 • Cgreater than NPET (approximately 7.5 • C). This is in line with the study conducted in Xi'an's cold region, which found a comfortable sensation at 29.7 • C [85].…”

To date, studies of outdoor thermal comfort (OTC) have focused primarily on physical factors, tending to overlook the relevance of individual adaptation to microclimate parameters through psychological and physiological behaviors. These adaptations can significantly affect the use of urban and outdoor spaces. The study presented here investigated these issues, with a view to aiding sustainable urban development. Measurements of OTC were taken at a university campus and in urban spaces. Simultaneously, a large-scale survey of thermal adaptability was conducted. Two groups were selected for investigation in a cold-winter-and-hot-summer (CWHS) region; respondents came from humid subtropical (Cfa) and hot desert (BWh) climates, according to the Köppen Climate Classification (KCC). Results showed that: (1) neutral physiological equivalent temperature (NPET) and preferred PET for people from the Cfa (PCfa) and BWh (PBWh) groups could be obtained with KCC; (2) PCfa adaptability behaviors were, subjectively, more adjustable than PBWh; (3) Clothing affected neutral temperature (NT), where NT reduced by approximately 0.5 °C when clothing insulation rose 0.1 Clo; and (4) Gender barely affected thermal acceptance vote (TAV) or thermal comfort vote (TCV) and there was a substantial relationship between thermal sensation, NT, and PET. These findings suggest ‘feels like’ temperature and comfort may be adjusted via relationships between microclimate parameters.

This study uses the universal thermal climate index (UTCI) and whole-body and local cooling assessment to determine the thermal benchmarks and cold risk for children in China’s severe cold regions. The relevant measurements and survey were conducted in four open spaces at a children’s park in Harbin, China. The findings of the study are as follows: (1) In winter, solar radiation and global temperature affects winter thermal sensation in male and female children the most. (2) Female children have a lower neutral UTCI (6.0 °C) than male children (7.3 °C), and female children have lower upper and lower thresholds of the neutral UTCI range (1.3–13.4 °C) than male children (0.6–14.1 °C). (3) Children who engaged in light-intensity activities, were exposed to cold winds, and touched cold surfaces with their bare fingers are at risk of whole-body and local cooling. (4) Children prefer exercising (PFemale = 35.5%, PMale = 48.3%) and moving to sunshine for thermal adaptation (PFemale = 31.1%, PMale = 26.4%). (5) Winter travel guidelines, cold-risk-prevention measures, and safety guidelines for winter outdoor activities are proposed. The results provide references for the design of open spaces in urban parks in China’s severe cold regions.

In recent decades, urban planners have endeavoured to mitigate climate change, by adaptation programs in order to alleviate its adverse effects on human health and wellbeing. Outdoor thermal comfort as an environmental factor affects human health, as proven by various research studies conducted in different climates. The aim of this paper is to explore the components of urban heat island, outdoor thermal comfort, and urban form. The relationship between these keywords and variables that affect outdoor thermal comfort was also analysed. The research method is descriptive-analytical and besides that, the qualitative research method has been used. The components of each keyword have been extracted based on professional theories. Finally, the ideal model of outdoor thermal comfort is proposed. This paper gives a comprehensive view to urban heat islands, urban form and outdoor thermal comfort
