FAQ
How to choose the best green roof system for my design goals?
Our experienced team reviews the specific project’s needs, design intents and any related by-laws and standards to help select the best option while considering cost, loading and aesthetics.
How to navigate municipal requirements and the Green Roof Declaration?
Leave the paperwork to us! Our experienced team will fill out and sign the Green Roof Declaration form. Have more questions about the City requirements? Please reach out and we will happily provide the answers.
Are NLSM vegetated systems wind tested? How Do We Get a P. Eng stamped letter?
Yes! NLSM’s vegetated systems are tested to CSA A123.24 and were subjected to 200 km/hour wind forces. We provide a project specific wind uplift letter stamped by a P.Eng upon request. Fun Fact: NLSM’s Dr. Karen Liu and Sasha Aguilera participated in developing the Canadian Standard Test Method for Wind Resistance of Modular Vegetated Roof Assembly – the first such test in the world. Tests were conducted at the National Research Council laboratory in Ottawa, Ontario and at the UL laboratory in Montreal, Quebec. Additionally, NLSM participated in the National Research Council Canada (NRC) field monitoring testing done at Humber College near the Toronto Pearson Airport.
In-Person Presentations or Live Webinars
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.
NutsN’Bolts: A-Z of Essential Tips to Achieve Success
This three part series navigates through the complete green roof process; from recognizing opportunities, to planning, to material selection and system design with emphasis on stormwater management, to specifications and drawings, to clarity in construction documents and, finally green roof aftercare and maintenance for long term success. (3 hours over 3 weeks)
Cost Saving Strategies to Meet Toronto’s Green Roof Policy
Love ’em or hate ’em green roofs are everywhere and can check off multiple requirements set out by the Toronto Green Standard (TGS) and the Wet Weather Flow Management Guidelines (WWFMG). This webinar explores functions and selection criterion, and the collaboration between architect, landscape architect and engineer to achieve specific design goals.
Wind Design for Modular Vegetated Roof Assemblies
Webinar about the CSA A123.24: Standard Test Method for the Wind Resistance of Modular Vegetated Roof Assembly (VRA) reviews the two key test components that measure wind uplift and wind flow resistances. Videos & case studies help demonstrate how VRAs behave at different wind pressures and wind speeds.
