Stormwater Management Performance Of Green Roofs, Andrew W. Sims
Stormwater Management Performance Of Green Roofs, Andrew W. Sims
Electronic Thesis and Dissertation Repository
Green roofs are gaining recognition in North America as effective tools for managing stormwater runoff in urban areas. A greater understanding of how green roofs perform with respect to fundamental stormwater management criteria, such as stormwater retention and peak flow attenuation is required. This study investigated the impact that changing climates have on the retention performance of three green roofs in London, Calgary, and Halifax. It was found that Calgary (67%) has significantly better retention performance then both London (48%) and Halifax (34%). However, London retained the greatest volume of stormwater (758 mm), followed by Halifax (517 mm) then Calgary …

Characterization Of The Green Roof Growth Media, Ginevra Alessandra Perelli
Electronic Thesis and Dissertation Repository
Green roofs are becoming a popular solution to manage the stormwater, to reduce the energy consumption in highly urbanized environment and provide many additional benefits. One of the key components that characterize the green roof system is the growth medium; the medium supports the plants, providing water and nutrient storage, and contributes to the roof insulation.
The object of this thesis is to investigate the hydraulic and the thermal properties of the green roof growth medium and to study the relationship among these properties through extensive laboratory analyses. In addition, the laboratory results are compared with direct measurements in the …
