“…Therefore, the need to mitigate these effects with shaded areas is reaffirmed. According to several researchers, thermal comfort is influenced by the socio-cultural, physiological, psychological and thermophysical factors of individuals [23][24][25][26][27][28][29]. In addition, the type of activity a person is performing outdoors should be considered in the thermal comfort assessment [30,31].…”

“…Other outdoor thermal studies were carried out in arid and dry climate cities [18] and in a slightly hot summer [22]. According to Peel [44], the city of Cordoba (Spain) is representative of many climatic zones in southern Europe, as in [20] and similar in [21,23,25,26]. It is classified as a Mediterranean climate (Csa).…”

“…Previous outdoor thermal comfort studies were carried out using a simulation through Envi-Met software [18] or using meteorological data measured by a stationary weather station [20][21][22][23]25,26] located far away from the city center. In contrast, in this experimental study, data were measured in situ on a tourist route using a mobile measurement pole to register a complete set of climatic variables, as in [23].…”

Heat waves are increasingly frequent in Europe, especially in South European countries during the summer season. The intensity and frequency of these heat waves have increased significantly in recent years. Spain, as one of the southern European countries most affected by these recurring heat waves, particularly experiences this phenomenon in touristic cities such as Cordoba. The aim of this study was to perform an experimental assessment of outdoor thermal comfort in a typical three-hour tourist walkable path of the historical center of Cordoba. The experimental study was carried out in the three-hour period of higher temperatures from 16:30 to 19:30 h CEST (UTC+2) on a normal summer day (6 July 2023), a day with a heat wave (28 June 2023) and a day with a higher heat intensity, called a super heat wave (10 August 2023). Environmental conditions such as a radiant temperature, ambient temperature, wet bulb temperature, air velocity and relative humidity were measured at three different heights corresponding to 0.1 (ankles), 0.7 (abdomen) and 1.7 (head) m. The results show extremely high levels of heat stress in all bioclimatic indices throughout the route. Cumulative heat stress ranged from “very hot” conditions at the beginning of the route to becoming “highly sweltering” at the end of the route. The average temperature excess over the thermal comfort threshold was very high and increased with the heat intensity. In addition, a correlation analysis was carried out between the bioclimatic indices studied, with the UTCI index standing out for its strong correlation with other thermal comfort indices. The findings emphasize the need for interventions to improve the urban environment and promote better outdoor thermal comfort for city dwellers through measures such as green infrastructure, UHI mitigation and increasing public awareness.

“…Furthermore, cloud cover plays an important role in computing the mean radiant temperature [31][32][33][34][35]. Several studies reported that personal parameters on a personal level such as age, gender, clothing, and activity levels influence human thermal stress [36,37]. Human thermal perception should be estimated by complex models due to food and beverage intake and clothing insulation [38][39][40].…”

Changes in extreme human bioclimate conditions are accepted evidence for and serve as a broad measure of anthropogenic climate change. The essential objective of the current study was to investigate past and future thermal bioclimate conditions across West Bengal (WB), India. The daily physiologically equivalent temperature (PET) was calculated by considering definite climate variables as inputs. These meteorological variables were captured from the Coordinated Regional Downscaling Experiment (CORDEX)-South Asia. The initial results from this research work present the mean monthly distribution of each PET class over the considered stations of WB during the period (1986–2005) and three future time periods: (i) near future (2016–2035), (ii) mid-future (2046–2065), and (iii) far future (2080–2099). It was observed that the months from April to June comprise heat stress months in terms of human thermal perception, whereas thermally acceptable conditions begin in November and continue until March for most stations. Results from future PET changes over WB in the context of the reference period (1986–2005) reveal a prominent increase in warm and hot PETs for all future time periods in two different greenhouse gas emission scenarios. During the far-future time period, stations within a kilometer of the Bay of Bengal such as Digha, Diamond Harbour, Canning, and Baruipur account for the highest percentage in the warm PET class (35.7–43.8 °C) in high-end emission scenarios. Simultaneously, during the period from 2080 to 2099, Kolkata, Dum Dum, Kharagpur, and Siliguri will experience a PET greater than 43.8 °C for close to 10% of the days in the year and more than 10% in Sriniketan, Malda, Asansol, and Birbhum. During the far-future period, a negative change in the very cool PET class (<3.3 °C) indicating a decrease in cold days was the largest for Darjeeling.

“…A comfortable outdoor environment can not only prolong the duration of outdoor activities and reduce the use of air conditioning, thus, reducing building energy consumption ( 5 ), but also optimize urban space utilization and enhance outdoor activities, social solidarity ( 6 , 7 ), public health ( 8 , 9 ), and tourism ( 10 ). Relevant studies conducted in different climate zones have shown that the regional thermal benchmarks of outdoor thermal comfort (OTC) need to be calibrated, due to the possible differences in their thermal history ( 11 ), social culture ( 12 , 13 ), and thermal adaptation of local residents ( 14 ), along with other factors. Therefore, determining the outdoor thermal benchmark of a region can help urban planners to design and plan open urban spaces effectively to enhance outdoor thermal comfort and improve urban microclimate ( 15 ).…”

Thermal comfort is an important indicator for evaluating the environment of urban public space, and appropriate thermal comfort can effectively prolong the duration of outdoor activities. In the existing studies, there is a lack of thermal comfort comparison between hot spots and cold spots. In this study, we selected the coastal city of Dalian in China as our study area and conducted field investigations on the thermal comfort of two landmark resorts, namely, a downtown commercial street and coastal leisure park. The study was conducted on typical summer days and consisted of interviewing several residents to understand their thermal comfort requirements. We investigated the thermal expectations of the interviewees through meteorological measurements and questionnaires. The universal thermal climate index (UTCI) was used to determine the thermal benchmarks of the on-site subjects. The results indicated that (1) globe temperature and air temperature were the most important factors that affected thermal comfort, followed by relative humidity and wind speed in summer daytime. (2) Shaded spaces are more comfortable than open spaces, and tree shade is preferred over artificial shade in coastal park. (3) The neutral UTCI (NUTCI) of the respondents were 24.1°C (coastal park) and 26.0°C (commercial street); the neutral UTCI ranges (NUTCIR) were 20.8–27.4°C (coastal park) and 23.3–28.7°C (commercial street). (4) The upper thermal acceptable range limits of the coastal park and commercial street were 30.2 and 32.1°C, respectively, which were substantially higher than the upper NUTCIR limit, indicating that the residents in Dalian were well-adapted to hot weather. The results can provide a good reference for determining ideal design strategies to optimize the thermal environment of urban outdoor recreation spaces in summers and improve the quality of life in coastal cities.
