Award Winning Green Roofs & Walls (Part 2)
At the start of the month, we posted this blog (Award Winning Green Roofs & Walls (Part 1) — Groof - #1 Green Roofs and More) and promised to keep the series alive with this Part 2 on the topic of awards in this industry.
EXAMPLE 1
Next Level Stormwater Management – Two Old Mill, An Award Winning Green Roof – Case Study (nlsm.ca)
Recipient of the Award of Excellence, Green Roof For Healthy Cities 2018 - Janet Rosenberg & Studio led by landscape architect Greg Warren designed the green roof to meet the Toronto Green Development Standard Tier II. Kirkor Architects designed the Tridel Condo to achieve LEED Gold Certification.

This roof is also wind tested, which is another topic for us to explore.
From the article
Beautiful mix of Extensive and Intensive Vegetated Roof Systems
The intensive green spaces have up to 1200 mm of engineered growing medium that supports various species of grasses, shrubs, deciduous evergreens, perennials and vines. Over 50 per cent of the species selected for the project are native to the area
Vibrant Palette
The extensive lightweight and “soilless” system used on Two Old Mill is 30 mm thick and is comprised of loose-laid base layers and a pre-vegetated mat. The mat includes 8-10 species of sedum and arrives mature with 80 per cent foliar coverage. This extensive system is beautifully blended with a vibrant palette of perennials planted in an intensive green roof system.

Award-winning Green Roof Designs – Schifferbooks
The organization that awarded the Green Roof at Two Old Mill in Toronto (see example #1 above) was started by Steven W. Peck - who started many things in this industry today. They also created this book in April 2008 -
From the book - “Award-winning Green Roof Designs : Green Roofs for Healthy Cities” See here.
Over 100 beautiful, informative photos display the green roofs technology that is quickly becoming a fundamental element of the emerging practice of living architecture. The award-winning roof designs displayed and described, for private homes, businesses, and public spaces alike, integrate natural and artificial systems, resulting in healthier, more sustainable buildings and communities… Green roofs have the capacity to deliver multiple public and private benefits. The projects depicted and discussed cover a wide geographic range from Manitoba to Florida, stretching from the mid-Atlantic coast to the Pacific. The projects are almost exclusively the product of multi-disciplinary, collaborative design processes. Details about the plants used, growing media, drainage and irrigation systems, and waterproofing, along with descriptions of challenges overcome, and innovations developed, are provided.
EXAMPLE 3
Award Winning Powderhouse Green Roof Project (livingarchitecturemonitor.com)
As the book above looks at award winning green roofs in Canada and the United States, we wanted to highlight this award winner from Somerville, MA - awarded by Recover Green Roofs (Recover Green Roofs | New England Green Roofs) who have been doing great work in this space since 2009 all over the U.S. This was awarded the Jeffrey L. Bruce Awards of Excellence for 2021 by GRHC which is the author of the book above’s organization.
Upon commencing construction, a number of logistical challenges had to be overcome, such as how best to reach the central courtyard and how to most efficiently convey materials from grade. As the project progressed, Recover followed the model of the Roman armies who built their highways as they traveled, allowing the build team to convey their materials along the route they were building.
This article about the project tells a great story with photos from the construction to the finished product below:
Stay tuned for Part 3 of this series which may include indoor (and outdoor) green walls and a rooftop farm.
