Abstract:Amidst escalating climate change and urban population growth, urban water infrastructures face unprecedented pressures. Green roof panels, as an innovative solution, have been developed to mitigate these impacts and enhance urban livability. This study aimed to evaluate the performance of extensive green roof panels in managing rainwater, particularly focusing on their capabilities in water retention, evapotranspiration, and water quality enhancement. Utilizing both a literature review and laboratory experiments, the effectiveness of these panels was assessed in controlled conditions. The results demonstrated that the panels absorbed an average of 81% of a simulated heavy rainfall (2.8mm/h), with evapotranspiration rates ranging from 12 to 16.8 ml/h. Moreover, water quality analysis post-filtration revealed a decrease in pH and a notable increase in turbidity, along with a slight rise in nitrite levels following the initial runoff. These findings suggest that green roof panels possess considerable potential for reducing peak rainfall impacts and mitigating urban flooding. However, given the discrepancies between laboratory conditions and real-world settings, there is a pressing need for further field testing and continuous monitoring. This would help substantiate and optimize the use of green roof panels for sustainable urban water management, aligning with broader environmental goals and enhancing urban quality of life.
