Hydrological performance of green roofs in the context of the meteorological factors during the 5‐year monitoring period

Abstract

Green roofs as solutions that can offer varying levels of stormwater management are the topic of current interest. In order to use this form of reconstructing retention capacity, it is important to understand the influence of meteorological conditions on the functioning of living roofs. The study presents the results of research, using of the ANOVA variance analysis method, on retention performance (i.e. volumetric control) and detention (temporal delay run-off) carried out in the years 2009-2014. The results indicate that the green roof can effectively retain rainfall and delay the initiation of run-off from the rainfall events included in the analysis. Understanding the hydrological performance of green roofs in different local meteorological conditions is key to the successful implementation and development of sustainable practices to control run-off in urban areas.

Assessing the Retention Capacity of an Experimental Green Roof Prototype

“…Comparing the 12 tests, it can be inferred that it is not only the intensity of rainfall that influences the time at which surface runoff begins, which indicates that there are other variables that influence this time. Discrepant values may be attributed to climatic variations and different weather conditions, including the characteristics of rainfall events and air temperature distribution [7]. In previous research, the antecedent dry weather period has also been identified as an important factor in influencing retention [7,75].…”

“…Accelerated urban sprawl thus calls for the need to guard against flood damage through the suitable design of new urban drainage networks that seek to integrate with the development of cities, and aim to reduce the impacts on the hydrological cycle, acting on both storage and infiltration processes [5,6]. There is no single simple solution in implementing the principles of sustainable stormwater management and source control of run-off [7]. Sustainable Urban Drainage Systems (SUDS), Best Management Practices (BMPs), Low Impact Development (LID), or Green Infrastructure (GI), which refers to practices and systems that use natural processes, including infiltration, evapotranspiration, and stormwater, have been applied to protect urban areas [8][9][10][11].…”

A pilot study on improve the functioning of extensive green roofs in city centers using mosses

“…Thus, environmental conditions on the studied rooftop are typical for strongly urbanized areas with the high air pollution. Detailed description of the roof platforms with photos of the site is presented in the papers by Burszta-Adamiak (2012) and Burszta-Adamiak et al (2019).…”

“…Since the year 2009, the authors have conducted research on extensive green roofs models (Burszta-Adamiak et al, 2011;Burszta-Adamiak, Stańczyk & Łomotowski, 2019). During that time it was observed a spontaneous colonization and development of mosses on the green roofs, which seemed to be well suited to the roof's environmental conditions.…”

A review of green roof incentives as motivators for the expansion of green infrastructure in European cities

“…Apart from the possibility to recreate biologically active areas in cities (partly, e.g. 50% in Poland), numerous studies confi rm the capacity of green roofs to retain rainwater and delay runoff, as well as to reduce the amount of pollutants in air, improve the microclimate and positively infl uence the urban heat island effect (Shafi que, Kim & Rafi q, 2018;Burszta-Adamiak, Stańczyk & Łomotowski, 2019). Another factor that is increasingly appreciated in cities, is the fact that green roofs provide friendly, green leisure spaces and improve the aesthetical values of buildings (Sutton, 2014).…”
