Presented by Dr. Karen Liu, Research & Development, Bonar Xeroflor
Green roofs have been consistently experiencing double-digit growth over the past decade. A major driving force has been stormwater management. This luncheon meeting will discuss how to design green roofs specifically for stormwater management and examine various municipal policies and programs and their pros and cons in promoting green roof installation for stormwater management.
The stormwater management potential of a vegetative roof depends on its water storage capacity as well as the rainfall pattern and climate zone where it is located. Water detention and retention characteristics of the individual components will be looked at and a review of how these components interact within a green roof system to manage stormwater runoff.
The sessions will also demonstrate how innovative water retention materials can maximize water storage while keeping the weight low. A concept of water-retention-to-weight ratio will be introduced to compare different green roof components to assist designers to make the proper choices.
A case study: The Broadway Tech Centre will be used to illustrate how these tools can be used in designing green roofs for stormwater management.
At the end of this presentation, participants will be able to:
Dr. Karen Liu is the product manager for Bonar Xeroflor. She has been conducting green roof research since 2000 when she was a research officer at the National Research Council (NRC) in Ottawa, and led the green roof research team at the British Colombia Institute of Technology (BCIT) in Vancouver. Karen established the first North American field facility dedicated to green roof research and conducted several field studies across Canada to study the climate sensitivity of the technology. She now focuses her work on product development at Bonar Xeroflor.
