ABSTRACT

The paper discusses results of the long-term monitoring of a full-scale pilot installation of a modular tray-based blue roof (BR) system for the control of the runoff from the roof terrace of a building in the campus of the University of Catania (Italy). The BR was installed in one catchment of the rooftop while another symmetrical catchment was left unmodified and monitored to allow comparison. Results of the analysis have shown average 54% retention efficiency and 72% detention efficiency of the BR. Comparatively, the BR always overperformed the conventional roof, with mean 34% runoff reduction and mean 60% flow peak attenuation. The paper discusses also limitations of the results obtained and potential for improvement of the system efficiency, including comparison with some of the results from the literature.

摘要

本文讨论了对用于控制卡塔尼亚大学校园建筑屋顶平台径流的模块化托盘式蓝色屋顶（BR）系统的全面试点安装进行长期监控的结果。 （意大利）。BR安装在屋顶的一个集水区中，而另一个对称集水区则保持不变并进行监控以进行比较。分析结果表明，BR的平均保留效率为54％，保留效率为72％。相比之下，BR的性能总是优于传统屋顶，平均径流减少了34％，流量峰值衰减了60％。本文还讨论了所获得结果的局限性以及提高系统效率的潜力，包括与文献中的某些结果进行比较。
