Engineering Green Roofs for CoV’s Rainwater Management Plan
Green roofs play a key role in the City of Vancouver’s (CoV) new simplified rainwater management (RWM) requirements for new Part 3 buildings that took effect on Jan 1. We will learn how to design green roofs to help meet CoV’s retention/detention requirements and when upgrading to a blue-green roof can increase ROI.
Engineering Green Roof Systems to Optimize SWM 2.0
2.0 is a deep dive into the latest stormwater retention and detention technologies. Learn to use modeling to meet water balance and quantity control targets through initial abstraction and irrigation water reuse. Recognize opportunities and limitations. Case study demonstrates performance and cost savings.
Strategies to Meet Policy & Design Goals in Toronto
Check off multiple requirements set by the Toronto Green Standard (TGS) & Wet Weather Flow Management Guidelines (WWFMG). Success requires collaboration between architect, landscape architect & engineers, as well as understanding components, their functions & selection criterion to achieve specific goals.
