Abstract
Rooftop gardens or greenroofs provide multiple benefits in support of
environmental sustainability such as improved stormwater management,
improved air quality, increased energy efficiency, increased roof life cycle and
decreased heat loading to the atmosphere contributing to the mitigation of the
"Urban Heat Island Effect". The objective of this paper is to design an on-site
evaluation for the quantitative benefits of the greenroof system. The study
describes the design and data collection of six greenroof systems in the Greater
Toronto Area, to specifically quantify the multiple benefits of greenroofs in
Canadian climate. The long-term, real-time monitoring program will help to
define the ecological and hydraulic benefits of the greenroofs. The findings of
this study will be used to support a region-wide database for the evaluation of the
pot
