Escalating climate change intensity requires a greater adaptive capacity to urban heat extremes. In response, cities are implementing outdoor facilities to mitigate urban heat and allow pedestrians to engage in outdoor activities during heat events.Local governments in Seoul, South Korea have installed sunshades, street trees, cooling fogs, green walls, and green roofs as climate change adaptation strategies. Previous studies emphasized the importance of preferences and perceptions of users in the effectiveness of urban infrastructure and landscape, and highlighted the impact of age on preferences and perceptions.However, current adaptation planning does not reflect variation across different age groups, nor does it consider user effectiveness; therefore, this study aims to identify variation in perceptions of the adaptive capacity of the five abovementioned outdoor heat adaptation facilities across age groups and to suggest implications for climate change adaptation strategies. To verify the variation, we used the Kruskal-Wallis test, and the results showed that the perception of green roofs varied across six different age groups from 15 to over 65 years old at a 95% confidence interval, and perception of green walls at a 90% confidence interval. Sunshades, street trees, and cooling fogs showed no significant variation across different age groups.Specifically, individuals aged 65 and older perceived green roofs as significantly more effective for adapting to outdoor heat than those aged 15 to 34. Similarly, this older age group found green walls more beneficial than the youngest group, aged 15 to 24. To further explore the relationship of the perception with behavioral features and socio-economic status, we performed correlation analysis. The results suggested that climate change awareness, heat sensitivity, and education could play a significant role in shaping perceptions of adaptive capacity based on outdoor heat adaptation facilities. Perception of high adaptive capacity of green walls and green roofs by older population along with significance of climate change awareness could be used as important information for effective adaptation planning especially in aging society.
