Introducing more trees, changing building density and surface cover and materials are examples of planning measures that can be used to mitigate heat stress. One challenge as an urban planner is to have knowledge on which mitigation measure to implement to achieve the highest cooling effect with regards to outdoor heat stress at different spatial scales. The aim of this high-resolution modelling of outdoor thermal comfort on city-wide domains is to examine how different real-world urban settings reduce or exacerbate heat stress with regards to building density (plan area index), tree fraction, and ground cover. Here, we exploit the open-source tool Urban Multi-scale Environmental Predictor (UMEP), to investigate how real-world data on building density, tree fraction, and ground cover influence thermal comfort in the three largest cities in Sweden. Mean radiant temperature (T<sub>mrt</sub>) and two thermal comfort indices are calculated and compared: Physiological Equivalent Temperature (PET) and Universal Thermal Comfort Index (UTCI). Automated chain processes using Python scripting is demonstrated, making it possible to derive microscale outdoor thermal comfort information (2-meter resolution) using a standard personal computer and open data sources. Results show that tree fraction is the single most effective outdoor heat mitigation measure, especially in areas with low building density. Results also show that building fraction has a minor cooling effect. This is probably due to the fact that shadowing at street level is dominated by trees due their 3D characteristics including trunk zones. T<sub>mrt</sub> shows very similar results compared with PET and UTCI, indicating that T<sub>mrt</sub> can capture the spatial variations of heat stress during warm, clear and calm days. Since trees is the single most effective measure to mitigate heat stress, it should be incorporated when creating practical guidelines to resilient urban planning strategies against heat stress.</p>","PeriodicalId":588,"journal":{"name":"International Journal of Biometeorology","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145111770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Urban green spaces serve as crucial venues for physical activity, social interaction, and mental restoration among the elderly, providing numerous health benefits. This study employed meteorological measurements and questionnaire surveys to investigate older adults' thermal perceptions and psychological responses to winter exposure in green spaces, comparing differences between two groups: those with chronic diseases and those without. The research specifically analyzed changes in thermal and psychological responses as participants transitioned from urban built environments to neighborhood green spaces and then returned to urban built environments. Such alternating experiences of diverse urban environments reflect the authentic Living conditions of urban residents. Findings are as follows: 1) Exposure to green spaces improved the psychological Health of older adults, with more significant and sustained improvements in emotional well-being for the chronic disease group. 2) The cold tolerance of the chronic disease group was inferior to that of the non-chronic disease group. Exposure to green spaces enhanced older adults' thermal comfort, increasing their tolerance to low temperatures, with more pronounced and sustained effects observed in the chronic disease group. 3) Psychological factors influenced older adults' thermal perceptions, with positive emotions serving as the key moderating variable. Urban green spaces could effectively enhance thermal comfort by mediating improvements in positive emotions, a benefit that is especially pronounced among older adults with chronic diseases. HIGHLIGHTS: Elderly showed better cold tolerance and mental health in green spaces vs. urban areas. Benefits of green space exposure on thermal and psychological health may be sustained.
