This study consists of nine case studies addressing thermal comfort in the public areas of city centres, with particular emphasis on the measurable effects of blue and green infrastructure on thermal exposure. Daytime on-site measurements were taken in summer in the paved areas of squares, in the proximity of water fountains, and in the shade of trees in order to evaluate levels of heat stress based on the universal thermal climate index (UTCI). The differences in UTCI values between the research points confirm substantial cooling associated with high vegetation (trees induced differences up to 10.5 °C in UTCI), while the measurable cooling effect of low vegetation was negligible (not more than 2.3 °C UTCI). It was also quite low around water fountains, spray fountains, and misting systems. It follows that municipal authorities should consider the differences in cooling effect potential of individual types of blue and green infrastructure when incorporating climate adaptation measures into urban planning.

捷克城市的夏季热舒适度：城市中心蓝色和绿色特征的测量效果

本研究包括九个案例研究，涉及城市中心公共区域的热舒适性，特别强调蓝色和绿色基础设施对热暴露的可衡量影响。白天在广场铺砌区域、喷泉附近和树荫下进行了白天现场测量，以根据通用热气候指数 (UTCI) 评估热应激水平。研究点之间 UTCI 值的差异证实了与高植被相关的显着降温（树木引起的 UTCI 差异高达 10.5 °C），而低植被的可测量降温效应可以忽略不计（不超过 2.3 °C UTCI）。喷泉、喷水器和雾化系统周围的水量也很低。
