Evaluating green roof performance

Andrew is working towards a Masters degree under the supervision of Dr. Denis O'Carroll. The project focus will be on quantitatively evaluating the performance of various aspects of green roofs. Green roofs have significant potential for flood alleviation through storm water reduction and attenuation, hydrologic benefits through increased storage and evapotranspiration, improved building insulation properties resulting in energy conservation, and improved aesthetics. There are two green roofs on campus at Western, both of which are equipped with instrumentation to collect data. Additionally, there are green roofs sites in both Calgary and Halifax which work with the green roof team at Western to provide data in a variety of climates. The interpretation of this data will be important in making design changes and optimizing all components of the green roof to achieve the highest performance possible.

Personal Background

Andrew completed his Bachelors degree in Environmental Engineering from the University of Guelph in the Winter term of 2013, and joined the RESTORE group the Summer of 2013. While at Guelph, Andrew conducted research under the supervision of Dr. Bill Van Heyst assisting in the completion of thesis work for two Masters students. The research, based on determining the feasibility of new sustainable technologies, produced a web based tool which simulates energy production and feasibility of sustainable energy options in agricultural settings. After graduation, Andrew had the opportunity to pursue masters research for the RESTORE group in his hometown of London, and eagerly accepted the new, challenging, and exciting experience.
