This year Grey to Green features five unique workshops and training courses, giving you the opportunity to customize your conference experience. Some training courses include a rooftop tour. Click below for more details on each workshop offering.

Green Roof Professional Exam

$495 CAD

“The GRP accreditation program stands out as one of the most comprehensive and intelligently designed sustainability training courses I have taken. GRP accreditation gives my organization the knowledge and credibility to guide our clients through the benefits and proper implementation of a successful green roof.”
— Stefan Hansmire, Co-owner, Ncompass Construction LLC

The accredited Green Roof Professional is an integrator, someone who is able to manage a project through the design and construction phases. This is someone who has a general understanding of what the industry refers to as the “black” arts and “green” arts - the living and non-living elements that must come together to result in a successful green roof. The GRP’s role is to:

  • Identify and pull everyone on the team together.
  • Function as a team leader for the green roof portion of a project.
  • Understand the different options for green roof design and implementation.
  • Maximize the benefits of green roofs during the design process (e.g., by identifying opportunities for integration with other building systems).
  • Understand the major challenges in implementing green roofs and the best practices associated with design and installation.

Passing the exam indicates that you have demonstrated knowledge and skills deemed important by the green roof industry at a given point in time. 

Date: Monday, May 8
Time: 3:00pm - 5:00pm
Location: Ryerson University (room TBC)

Green Wall 101: Systems Overview & Design


The Green Walls 101: Introduction to Systems and Design course discusses design and construction best practices for green facades and living walls, as well as the latest research findings on the environmental benefits of these technologies.

  • Determine major functions and components of green walls;
  • Describe characteristics and assess various advantages of different green wall systems;
  • Understand market drivers encouraging green wall implementation in North America;
  • Understand how to design green walls for maximum benefits and LEED™ points.

The half-day training course will be complemented by a green wall walking tour in the afternoon. Tuition includes the course, Resource Manual and tour. 

This course is approved for 3.5 Continuing Education Units (CEUs) for GRPs

Instructor: Brad Bass, PhD, Researcher, Environment Canada; Adjunct Professor, University of Toronto

Date: Wednesday, May 10
Time: 8:30am - 5:00pm
Location: Morning - Ryerson University (room TBC) // Afternoon - Tour

How to Properly Construct Low Impact Development Stormwater Management Practices


This course trains designers, contractors, and others involved in the design, construction, and inspection of LID. Over a half-day, we will cover LID installations ranging in size from small parking lot retrofits to large subdivision developments that are fully reliant on LID approaches to stormwater management. Participants will be taken through each step of the LID construction process, highlighting potential errors and explaining proper techniques. Lessons learned from examples in Ontario’s cold climate will be shared.

The half-day training course will be complemented by a tour to three different local LID sites: CVC’s Head Office, as well as the Elm Drive and Wychwood sites. Performance results will be discussed. 

  • Identify how LID construction differs from the construction of a conventional stormwater management site.
  • Understand the roles and responsibilities of the LID construction team members.
  • Understand LID construction considerations from mass grading through final assumption.
  • Know the common methods for constructing LID practices and specifying their materials.
  • Effectively stabilize and establish vegetated stormwater management practices.
  • Be aware of common construction pitfalls and how to avoid them.

Instructor: Kyle Vander Linden, Water Resources Specialist, Credit Valley Conservation

Date: Wednesday, May 10
Time: 8:30am - 5:00pm
Location: 255 Old Derry Road, Mississauga, ON L5N 6R4

Integrated Water Management for Buildings & Sites


Developed jointly by GRHC and American Society of Irrigation Consultants (ASIC) committee members, this course provides technical and economic information on the design and performance of a fully integrated site and building water management system based on the “Net Zero Water” concept.

This approach promises to significantly reduce the consumption of potable water in buildings, reduce discharge to municipal waste water systems, and save on municipal energy by reducing the amount of potable water treated at municipal facilities. The recognition of the connection between water management and energy conservation is emerging as a new opportunity in integrated management systems.

Key concepts and terminology are illustrated by case studies and demonstration projects which identify issues and opportunities associated with:

  • Costs and benefits
  • Design and engineering practices
  • Installation and maintenance requirements
  • Efficiency and performance of a fully functional integrated site and building water management system based on the “Net Zero Water” concept.

Instructor: Jeffrey Bruce, GRP, FASLA, ASIC, LEED, Principal, Jeffrey L. Bruce & Company

This course is approved for 3.5 Continuing Education Units (CEUs) for GRPs.

Date: Monday, May 8
Time: 8:30am - 1:00pm
Location: Ryerson Unversity (TBC)

Introduction to Rooftop Urban Agriculture

$249 CAD (GRHC Member)
$275 CAD (Non-Member)

“I participated in the half-day and inaugural class: Introduction to Rooftop Urban Agriculture. Of the 101, 201…classes, trust me, I’ve taken them all, I thought this was the most relevant, informative and interesting class…ever.”
— Janet M. Faust, LEED AP, GRP, Greenroof Product Manager, JDR Enterprises, Inc.

This course discusses multiple approaches to growing food on rooftops through design and maintenance principles, and case studies drawn from across North America.

Learn about:

  • The diversity of physical applications of urban agriculture and the growing technologies that apply.
  • The social, environmental and economic benefits of urban agriculture and rooftop farming.
  • The governance, personnel and economic options for implementing urban agriculture and rooftop farming systems and operations.
  • The conditions that lead to a successful urban agriculture project.
  • Strategies for overcoming common challenges associated with developing an urban agriculture/rooftop farming project.
  • Basic installation and maintenance principles.

The half-day training course will be complemented by Ryerson Urban Farm. Tuition includes the course, an 85-page course manual and tour.

Instructors: Arlene Throness, Urban Farm Manager, Ryerson Urban Farm; Jayne Miles, Urban Farm Programs Coordinator, Ryerson Urban Farm

Lighting for Indoor Vegetable and Medicinal Crop Production and Living Walls


Lighting is essential in indoor plant production (e.g., high value vegetables, cannabis) or for beautifying and improving our environment (e.g., living wall). Horticultural Light Emitting Diode (LED) technologies have been rapidly developing in recent years with many commercially-available LEDs to choose from.  This workshop will provide you with background knowledge and some hands-on experience on light selection, monitoring and applications. 

  • Knowledge on how plants respond to both light spectra and intensity.
  • Overview of existing lighting technologies, including LEDs, high pressure sodium, metal halide and fluorescence.
  • How to choose the right lighting technology for your application.
  • How to choose and use the light sensors to make sure your plants are getting the light you intended.
  • All related questions on horticultural lighting are addressed.

Instructors: Youbin Zheng, PhD., Associate Professor. School of Environmental Sciences, University of Guelph; David Llewellyn, Senior Research Associate, School of Environmental Sciences, University of Guelph
