“…As a result of evaluating the benefits of microclimate in previous study, the results indicate that asphalt pavement is the worst option, while cool pavement integrated with vegetation is much more beneficial to human health [39]. Also, it was discovered that green roofs and cool roofs have the effect of reducing surface temperatures by changing the albedo of the roof surface based on a microclimate analysis of the urban scale [25]. The results of this study also showed similar results to previous studies; urban heatwave mitigation strategies such as cool roofs and cool pavements are effective in reducing temperature and also have an effect on humans.…”

“…A long-term accessibility study showed that a cool roof reduced summer peak temperatures by up to 4.7 • C [24]. An urban heatwave response project estimated temperature reduction rates using a microclimate analysis modeling approach [25]. A thermal infrared image acquired by a drone was analyzed to determine the effects of heat island reduction techniques during a heatwave [26].…”

Various types of damage, including health risks, caused by abnormal climate conditions have gradually increased in recent years, particularly in cities with a high degree of complexity. In particular, it is important to address heatwave damage risk from both technical and policy perspectives because it poses risks to older adults and/or disadvantaged individuals. This study was performed to assess the quantitative effects of two heatwave mitigation measures, cool roofs and cool pavements, in the Jangyumugye district of Gimhae, Republic of Korea. Thermal imaging cameras were used to measure surface temperatures after the installation of these measures; after the installation of cool roofs, indoor temperatures were also measured using temperature measurement data loggers. Then, a survey was conducted to obtain feedback from users of the associated facilities. From August to October 2019, surface temperatures were significantly reduced following the installation of cool roofs and cool pavements. Cool roofs constructed using slabs and panels provided average temperature reductions of 15.5 °C and 11.6 °C, respectively. Cool pavements showed a temperature reduction of ≥4 °C in both parking lot and alley sites. More than 30% of users noticed a reduction in temperature as a result of heatwave measure installation. These results may be used by the city to make informed policy decisions regarding the implementation of heatwave mitigation measures.
