“…Reductions in runoff for the purple roof compared to conventional and green roofs were 88% and 55%, respectively. In the Mediterranean climate in southern Italy, a study [44] investigated the retention performance of BR on a building rooftop. The BR covered an area of 4600 × 5720 mm (15.1 × 18.8 ft) with 64 tray modules spaced at 400 mm.…”

The intensity and frequency of extreme rainfall events have increased in North America and the world due to climate change. Extreme rainfall events, characterized by a heavy volume of rainfall in a short duration, have triggered the onset of urban flash floods. Over the years, flash flooding has been reported in different cities in Canada, which resulted in many losses. Subsequently, different green roofing systems have been adopted to control urban stormwater runoff as part of Nature-Based Solutions (NBS) to mitigate urban flood and build a flood-resilient city. Currently, no specific widely recognized standard or code is dedicated to determining the hydrological performance of green roofs as a whole system. Moreover, there are no test protocols to regulate the design of green roof systems in the market. A comprehensive literature review examines existing research methods adopted to evaluate influencing parameters affecting the hydrological performance of NBS-CR. The results indicate several limitations in experimental and field investigations. Consequently, to address these limitations, it is essential to formulate a multi-functional work plan to develop a standardized test method that can become a common platform for the roofing industry to test and quantify the hydrological performance of their systems.

“…Few main components are retention ponds, infiltration trenches, rainwater harvesting systems, green roofs, blue roofs, pervious pavements, infiltration basins, etc. (Campisano et al, 2021;Fletcher et al, 2015;Joshi et al, 2021;Luo et al, 2020;Nascimento et al, 2019;Zhou, 2014). Each of the SuDS components in the field has its own benefits and demerits compared to others.…”

“…The Ontario Storm-water Management Planning and Design Manual also recognizes storm-water control from rooftops. It identifies approaches that divert water from roof leader to ponding area and roof leader to soak away pits as acceptable storm-water management practices [10][11][12][13][14][15]. Essentially the rooftops are designed with system that can release rainwater gradually into the storm-water system, and/or to facilitate its infiltration into the ground.…”

Low-sloped roofs such as commercial and high-rise buildings in a dense urban area provide vast “unused” surfaces that can be used to manage storm-water and mitigate urban flooding. Storm-water Detention Assembly (SDA) known as “blue roof” exerts advanced drainage technologies and operational strategies to store-and-release storm-water during and after heavy rainfall events. SDA can reduce peak flow and decrease storm-water run-off volume. However, the SDA application is limited due to the lack of science-based regulatory requirements. This paper introduces SDA, summarizes the benefits and challenges of this system, reviews the existing code specifications on roofing drain systems, and documents the criteria to design and construct SDA. With this systematic approach, the missing links are identified that shall form code change request for possible inclusion in the National Building Code of Canada (NBCC) and National Plumping Code of Canada (NPC). In addition, a road map is stated to calculate and benchmark the drain requirements on low-sloped roofs for a given design climatic load.
