Temporal Variability In The Daytime Green Roof Energy Balance During Drying Periods, Dimuth C. Kurukulaarachchi

Electronic Thesis and Dissertation Repository

Green roofs are a building design element intended to increase evaporative cooling in cities during the summer, which helps alleviate the daytime impacts of heat on human health and energy consumption, and supports mitigation and adaptation to the local effects of climate change. Time varying energy balances were measured on a 0.15 m deep, ~ 60 m² modular green roof with Sedum spurium in London, Ontario for the summer of 2014. A lysimetry approach was used to measure latent heat Q_E. Net radiation Q^* and ground heat flux Q_G were also measured, with sensible heat …
