The landscape architecture studio at FORREC was tasked with creating an exterior for the new student centre at York University, Toronto. This project serves as an example of the benefits of a contemporary, collaborative construction effort between the client, other stakeholders, end-users, and the design and construction teams.

Welcoming its first students in September 2018, the Myhal Centre for Engineering Innovation & Entrepreneurship, University of Toronto (U of T), Ont., is designed to enable collaboration between researchers, students, industry partners, and alumni. This nine-level, energy efficient building includes prototyping facilities, multidisciplinary research hubs, design studios, and technology enhanced learning spaces.

High above the ground, vegetated roofs mimic nature, helping clean the air, cooling down temperatures, keeping rainfall onsite, and alleviating pressure on urban stormwater systems. Vegetated roofs typically include a vegetation layer, growing medium, retention layer, drainage, and a root barrier.

On Wednesday, February 21, the CSC Montréal Chapter will host its first dinner-conference of the year. The event, which will address green roofs, will be held at Québec Tourism and Hotel Institute, from 6 to 8 p.m.

From a purely economic perspective, the positive impact of a vegetative ‘green’ roofing assembly is measured in the long term—40 years or more. This means ensuring its performance and safety over an extended period is crucial. A green roof protects the underlying waterproofing membrane from the elements. Combined with a higher-quality membrane necessary to resist soil and plant forces, the result should be a longer roof lifecycle decades beyond a conventional system’s 20 to 25 years.

Green roofs are continuing to gain recognition as a sustainable building design feature throughout North America. These vegetated assemblies contribute to many credits under the Canada Green Building Council’s (CaGBC’s) Leadership in Energy and Environmental Design (LEED) program.
To ensure performance of these systems, the Single-ply Roofing Industry (SPRI) association has passed two design standards and a test procedure specific for vegetative roofs in the last couple of years.
