Comparative microclimate and dewfall measurements at an urban green roof versus bitumen roof

Green roof can significantly reduce runoff volume and delay the duration of rainwater compared to a conventional roof; however there is insufficient research in China regarding rainwater retention performance. In this research, a comparison of a green roof with a conventional roof on rainwater retention is quantified. Results suggest that the specified sedum green roof delays the start and end time of runoff for 3 –13 and 4 –8 minutes. Artificial rainfall runoff retention ranged from 52.86% to 71% for the green roof. On the retention efficiency, potential 3141.77 ×104m3rainwater could be retained by urban green roof in Jinan. The green roof is demonstrated an optional measure to reduce the quantity of rainwater entering already overburdened city drainage systems with great huge economic and environmental benefits.

For the deteriorating urban ecological environment, the green roofs, as an important component of the urban landscape, play a positive and important role on constructing harmonious and natural urban environment. This article is focused on the analyses of the technical characteristics of green roof system and its structure, and also on the demonstration of the important effects of green roofs in areas such as energy-saving, emission reduction and eco-environment.

Current research does not integrate these benefits in the planning of green roof systems. The objective of this research is to develop a planning tool to evaluate storm water and energy benefits of a green roof structure. To demonstrate the planning tool, a case study of urban green roofs was conducted for three different building scenarios: residential, commercial and industrial buildings. Using the data collected at York University's green roof, the seasonal storm water and energy benefits in dollar values of each scenario were simulated. The study concluded that it is more important to select a proper soil mixture and type of plant when designing a green roof system. By understanding the stormwater and energy benefits, it is hoped that this research could accrue through the adoption of green roofs in Toronto as well as other Canadian cities.
