“…17 Older people are vulnerable to climate-related diseases such as cardiac arrest, pneumonia, and dehydration. 60 Improving the quality of outdoor places, increase the chance of using outdoor spaces and as such enhances their health and social life by helping them to remain active and interact with other people. 17,61 In other words, high-quality outdoor areas can improve the elderly's mental and physical health and well-being.…”

“…63,64 Larriva and Higueras (2020) showed the contrast between the subjective perception of older adults with real environmental measurements in outdoor places, highlighting their vulnerability to thermal stress and noise pollution, as potential health risk. 60 Applying international OTC indices and standards in different locations without addressing social and cultural backgrounds results in inaccurate results. But, due to the complex nature of human-based features and parameters, only limited studies have addressed them in OTC studies.…”

Increased urban air temperature considerably affects the health, comfort and consequently the quality of life in urban spaces. Urban design and planning studies, therefore, face an increasing challenge as they aim to improve Outdoor Thermal Comfort (OTC) and microclimate conditions of urban environments. Analysing OTC is more challenging when compared to indoor thermal comfort since a wider range of interrelated parameters exists in outdoor environments. Therefore, this research aims to classify urban studies that investigate OTC by conducting a comprehensive review based on key metrics such as approaches taken, methodologies and spatial and temporal scales. By extracting the key findings, this research forms an integrated framework of these metrics that presents a thorough view of the OTC concept in the context of climate-sensitive studies. Furthermore, this research elaborates on the main two groups of parameters affecting OTC including environmental and human-based parameters. Exploring the intricate inter-relationships of these two groups of parameters clarifies their contribution to OTC. Results of this study help architects and urban planners to improve their climate-sensitive strategies and support the decision-making process by providing a comprehensive perspective about different aspects of OTC. Finally, recommendations for future research are outlined.

“…Although the thermal comfort zone of the outdoor spaces obtained from previous cases located in different climate zones varied widely, such as the climate zones across Europe reporting a difference of 10 °C in thermal neutral temperature, many researchers recognized that outdoor thermal comfort is the main factor that determines the quality and use of outdoor spaces [22,23]. However, the present study showed that Ta and RH differences between indoor and outdoor spaces were the primary meteorological factors that influenced the elderly's usage of outdoor spaces.…”

“…However, in summer, the mean Ta of outdoor spaces was higher than the low-heat mortality Ta limit of 29 °C. The elderly are more sensitive to high temperatures [23]. Together with the UTCI values, it is necessary to decrease Ta of all outdoor spaces in summer, especially the garden and roads.…”

“…However, the above benefits the elderly obtained were based on the premise that the outdoor spaces were sufficiently comfortable to attract the elderly to use and enjoy these [20]. Previous research indicated that thermal comfort was one of the main factors that determine the quality and use of outdoor spaces [21][22][23]. In the hot-dry Mediterranean regions, the internal gardens provide a passive cooling effect to attract people to enter them [24].…”

The Influence of Transient Changes in Indoor and Outdoor Thermal Comfort on the Use of Outdoor Space by Older Adults in the Nursing Home

et al. 2022

Recently, the requirements regarding the environment of nursing homes are high, because the elderly are a vulnerable group with limited adaptive capacity to respond to transient environmental change. This paper presents a field investigation on the influence of transient thermal comfort changes between the indoor and outdoor spaces (i.e., air temperature (Ta), solar radiation (SR), relative humidity (RH), wind speed (WS), and the thermal comfort indices of Universal Thermal Index (UTCI)) on the willingness of the elderly to use outdoor spaces of the Wanxia nursing home of Chengdu City. Results indicated that, in summer, the mean UTCI values of indoor and corridor spaces corresponded to the level of moderate heat stress, while those of road and garden corresponded to the strong heat stress level. Road and garden spaces even showed moderate heat stress in spring. Approximately 28.93% (139) of the elderly living here used outdoor spaces every day. The morning period (from 9:00 a.m. to 10:00 a.m.) was the elderly’s favorited period for using outdoor spaces in seasons. The microclimatic transient differences between indoor and outdoor spaces ranged from 0.47 °C to 2.93 °C (|ΔTa|), from 86.09 W/m2 to 206.76 W/m2 (|ΔSR|), from 5.29% to 14.76% (ΔRH), from 0.01 m/s to 0.07 m/s (|ΔWS|), and from 0.25 °C to 2.25 °C (ΔUTCI). These big microclimate differences could cause enormous health risks for the elderly in the process of indoor and outdoor space conversion. The minimal transient change occurred between corridors and indoors. Pearson correlation analysis indicated ΔTa and ΔRH between indoor and outdoor spaces were the primary meteorological factors that influenced the elderly’s willing to use outdoor spaces. The elderly preferred to live in a constant Ta and RH environment. Only when the ΔTa and ΔRH are small enough to resemble a steady-state (ΔUTCI ≤ 0.5 °C), ΔWS and ΔSI could affect the elderly’s choice of using outdoor space. Optimal design strategies were put forward for reducing the transient differences between indoor and outdoor microclimates to inspire the elderly to use outdoor spaces safely, including improving outdoor canopy coverage and indoor mechanical ventilation.
