“…The value of S max will depend on green roof configuration. However, empirical data presented by Stovin et al (2012) suggest a typical value for S max on an extensive green roof with 80 mm substrate of 20 mm.…”

This paper outlines the development of a conceptual hydrological flux model for the long term continuous simulation of runoff and drought risk for green roof systems. A green roof s retention capacity depends upon its physical configuration, but it is also strongly influenced by local climatic controls, including the rainfall characteristics and the restoration of retention capacity associated with evapotranspiration during dry weather periods. The model includes a function that links evapotranspiration rates to substrate moisture content, and is validated against observed runoff data.to typical extensive green roof configurations is demonstrated with reference to four UK locations characterised by contrasting climatic regimes, using 30-year rainfall time-series inputs at hourly simulation time steps. It is shown that retention performance is dependent upon local climatic conditions. Volumetric retention ranges from 0.19 (cool, wet climate) to 0.59 (warm, dry climate). Per event retention is also considered, and it is demonstrated that retention performance decreases significantly when high return period events are considered in isolation. For example, in Sheffield the median per-event retention is 1.00 (many small events), but the median retention for events exceeding a 1 in 1 yr return period threshold is only 0.10. The simulation tool also provides useful information about the likelihood of drought periods, for which irrigation may be required. A sensitivity study suggests that green roofs with reduced moisture-holding capacity and/or low evapotranspiration rates will tend to offer reduced levels of retention, whilst high moisture-holding capacity and low evapotranspiration rates offer the strongest drought resistance.

“…green roofs require no additional space beyond a buildings footprint (Zhang & Guo,188 2013; Stovin et al, 2012). Furthermore, green roofs can be retrofitted onto existing 189 buildings as well as incorporated into new developments (Castleton et al, 2010).…”

“…In urban areas roof areas are accounted approximately 50% of the total area [STOVIN et al 2012]. This large amount of area if convert into green roofs can give many benefits in an urban area, including stormwater management [HOSSAIN, BAHAUDDIN 2013;SHAFIQUE et al 2016;SURMA 2015], control heat waves [FENG et al 2013;SANTAMOURIS 2014], increase biodiversity, improve the air quality of an area [LUO 2009], increase life span of the building, reduction in noise, and energy consumption costs [LUO 2009;SAIZ et al 2016;XIAO et al 2014].…”

Green blue roof has the potential to reduce the surface temperature of the building in the urban areas. Green blue roof is a new innovative low impact development (LID) practice that has exhibited an option to mitigate the heat island phenomena in urban area. This is the modified form of green roof that has ability to store rainwater in vegetation, soil layer and increases the evapotranspiration rate which decreases the temperature of an area. For this purpose, green blue roof is installed at the Cheong-un middle school building roof, Seoul, Korea. During the different time scenarios the surface temperature from the green blue roof and control roof were analyzed and their results were compared with each other. The results revealed that the surface temperature of green blue roof was much less as compared to control roof under same climatic conditions. From the results it is also concluded that surface temperature value of green blue roof was less than 5°C to 9°C as compared to control roof.
