"Sky Meadows - Integrating People and Nature: Sustainable Green Roofs and Roof Gardens" with Dr. Nigel Dunnett

Green roofs represent a unique opportunity for inserting large areas of diverse, naturalistic, biodiversity-supporting, and beautiful vegetation into the heart of our urban areas: an opportunity that is virtually impossible to repeat in the same way on the ground.

Sustainable solutions now exist for all contexts: large and small, public, private, intensive through to extensive.  Drawing upon the dramatic potential of dryland vegetation around the world, and his own research and practice, the author looks again at the ethical and aesthetic considerations for creating green roofs that are exciting for people, beneficial for wildlife, and low in resource-use.

Panel Presentation "The Portland Ecoroof Program: A Cross-section of the Green Roof Movement in Portland, Oregon" with Tom Liptan, Matt Burlin, Amy Chomowicz, Casey Cunningham, and Alice Meyers.

The Portland Ecoroof Program started in 1996 when a city employee constructed an experimental ecoroof on his garage. From this small start, the program has grown and as of July 2011 there are over 420 green roofs of varying sizes, on all types of buildings, from multi-story apartment complexes and commercial buildings to humble sheds, kiosks, and garages. These green roofs cover nearly 30 acres of Portland rooftops (extensive and intensive roofs).

The Portland Ecoroof Program consists of technical support, incentives, education, policies, and research. The program is incentive-based rather than regulatory, and the city’s policies reflect this approach. This presentation provides an overview of how these program elements work with the private sector and general public to sustain the green roof movement in Portland.

6:35-6:50 pm (22:35-22:50 GMT):15-Minute Live Q & A with Tom Liptan, Amy Chomowicz, Casey Cunningham, and Alice Meyers.

Featured Video: "The Vertical Garden - from Nature to Cities" An Interview with Patrick Blanc

Since more than half the human population is now living in cities, the façades of the high rise building must be seen as a valuable place for bringing back the nature into the cities.

For each new single project, I have answered with new shapes and new plant species.  The Vertical Garden is no longer a vertical panel; it is now possible to freely create it on various structures like columns, spirals, slopes or even vegetal ceilings.

Patrick is interviewed at length by Linda Velazquez in early September, 2011 at the Hotel Sofitel Chicago Water Tower; his video presentation that follows was filmed previously in front of a live audience.

4:00-5:05 pm (20:00-21:05 GMT):

Panel Session "Greenroofs: Wind & Fire" with Kelly Luckett, Mike Ennis, and Jim Kirby.

No longer can the green roof be deleted from a project due to failure to comply with the fire code. After three years in the making from members of Single Ply Roofing Industry in cooperation with Green Roofs for Healthy Cities (GRHC), we now have a green roof design guide for minimizing the risk of fire on green roofs.

The securing of a place in mainstream construction through the International Code Council (ICC) has resulted in a milestone for the North American green roof movement. Fire concerns are only half of the code story as the wind design guide is still progressing through the ANSI process - we must overcome both the wind and the fire obstacle. Kelly Luckett, President of Green Roof Blocks, moderates and shares his experiences representing GRHC with the consensus based ANSI/SPRI VF-1 and RP-14 standards. Jim Kirby, NRCA’s AED, Technical Communications, provides NRCA commentary about building codes, vegetative roofs and RP-14. Mike Ennis, Technical Director for SPRI, speaks to SPRI’s leadership leadership in the development of fire and wind standards and experience in the building code arena.

Wolfgang Ansel

"Green Roof Policies - An International Review of Current Practices and Future Trends"

Green roof policies are one of the basic key factors for the successful development of a green roof market.  Longstanding experiences and case studies from different countries and municipalities are creating a source of ideas that can be adapted and modified according to the needs of the local green roof stakeholders.  The presentation will highlight success stories and failures likewise.  Information from Europe, North America and Asia will be merged into a "Best Practice Guideline for Green Roof Policies."


Roland Appl

“Combining Green Roofs with Photovoltaics”

The synergy effects of combining green roofs with photovoltaics are not limited to their installation – the substrate serves as ballast against wind-uplift – they are also noticeable in their operation: solar module efficiency is normally linked to temperatures. As evaporation from the green roof cools the photovoltaic modules, in turn the process increases their efficiency – this is an important contribution to the environment and to climate protection.


Jörg Breuning

"Green Roof Technology Sails Around the World"

Playing golf, croquet or bocce in the middle of the Atlantic Ocean may sound like a far fetched dream.  However, Green Roof Service LLC in Bel Air, Maryland made this dream come true for Royal Caribbean and their half a million guests.  In this seminar Jörg Breuning explains the engineering and installation of live grass on Cruise Ships that face some of the most extreme environmental challenges.  Nice, green, and beautiful, it is the ultimate green roof experience.


Matthew Dillon

"GreenRoofs in Australasia"

As the impacts of climate change have now become a significant political issue and a major public concern in Australia there is a growing support for green infrastructure technology for the built form in urban planning.

This is a chronological record of the industry in Australia from 1986 - 2011 and the role which GreenRoofs Australasia has played, as the peak body promoting the industry.


João Manuel Linck Feijó

"The Work of ATVBrasil"

ATV Brasil is a non profit association whose objectives are to promote the construction of green roofs and vegetated walls in Brazil whose mission is to supply background information for legislation, to incentivize research, and to show the impacts of vegetated roofs in urban ecology.

Various greenroof projects and both interior and exterior Brazilian greenwalls are visited and discussed.


Richard Hayden

"Sloped and Complex Green Roofs"

No longer are green roofs relegated to the world of flat roofs.  Architects and designers are discovering the nearly unlimited design potential of incorporating green roofs as an integral part of the composition of the building.  From simple sloped roofs to complex combinations of curves and planes, green roofs are being blended with architecture in very unique ways.  This presentation outlines the challenges and solutions to helping architects and designers meet their design intent for their buildings. Examples of a variety of sloped green roofs from around the United States will be explored to outline the technical solutions that were developed by American Hydrotech to achieve the desired result.  Architects and designers will be able to see that their imagination is the only limiting factor in blending green into their designs.


Paul Kephart


"Naturalism: Large-Scale Applications of Living Architecture"

Design can mimic natural processes integrating them into site and structure.  The resulting spaces efficiently utilize ecosystem services enhancing habitat, infrastructure, and user experience within a context of integrated biological systems.  Vegetated systems foster and promote biological treatment of water and air.  Treatment occurs through biological, physical and mechanical processes, all of which can be integrated into buildings systems.  Paul Kephart will discuss large-scale applications of living architecture including the Transbay Transit Center, CPMC Cathedral Hill Hospital, and the Vancouver Convention Centre.


Haven Kiers and Linda Velazquez

"2011 Top 10 List of Hot Trends in Greenroof & Greenwall Design"

This is our fifth anniversary of the “Top 10 List” and an amazing amount of development has occurred over the past five years in the vegetative roofing industry.  Projects that were once scoffed at and considered impossible to get built are popping up all over the globe, and greenroofs are no longer considered fringe architecture, destined to be the first sacrifice to value engineering.  To honor the new ubiquity of architectural greening, this year our Top 10 will focus on greenroofs at all different scales, from micro to macro.  As “vegitecture” increasingly becomes a mainstay of both sustainable and cutting edge design, the list of greenroof and greenwall trends continues to expand.  This year we’re showcasing greening at both the micro and the macro scale, from small scale DIY greenroof projects to towering skyscrapers stacked with fruit and vegetable crops, parks, and energy facilities atop sky gardens, walls and bridges.


Terry McGlade


"Constructing Gardens in the Sky"

Each greenroof has its own design.  Sites that appear similar are not, given wind patterns, sun patterns, slope and drainage issues.

This presentation delves into case studies of three different greenroofs both from an installation perspective and a lessons learned perspective.  Biodiversity of each roof is discussed along with growth habits of the installed greenroofs.  Assumptions in the original design concepts are re-evaluated vis-à-vis the existent greenroof.


Lluis Recasens Pahí

"Sustainability in Plant Production"

Sustainable crop production is addressed with a focus on greenroofs and walls in the areas of Reus, Ampurias, Guadalajara, Tarragona, and Barcelona, Spain, utilizing plant selections with minimum agronomic requirements (low demands on maintenance, water intake, and disease control) as well as contemplating the use of environmentally friendly and respectful materials.  Using these technologies will ensure more sustainable parterres, greenroofs, and greenwalls through their material selection and plant diversity.  By using biodegradable materials and encouraging recycling and biodiversity, we reduce our water requirements and the maintenance program is respectful of the environment and the ecosystems, plus we contribute to the implementation and popularization of these sustainable processes.  This presentation will be in Spanish with English subtitles. 


Steve Ritz

"The Green Bronx Machine"

Originally slated to precede the "Greenroofs & Walls for Educational & Social Equity in the Bronx" Panel Session with Robert Bieder (Moderator), Jon Beuttler, Jess Dannhauser, Bronx Borough President Ruben Diaz Jr., Javier Lopez, New York State Senator Gustavo Rivera, and Steve Ritz but cut due to time restraints, "The Green Bronx Machine" PowerPoint Presentation is shown in its entirety.

This presentation gives an overview of some of the current issues in the Bronx as well as the positive effects of the Green Bronx Machine.


Dr. Clayton Rugh

"One Decade of Ultralight Green Roof Proof-of-Concept on Ford's Dearborn Truck Plant"

In 2001, the Ford Motor Company, Xero Flor America, LLC., and Michigan State University began collaborative green roof research trials resulting in the installation of the massive 10.4 acre green roof on Ford’s River Rouge Truck Plant in Dearborn, Michigan.

The Ford project held the record of "The World's Largest Green Roof" for several years and has matured into a thriving, healthy, low profile vegetated roof which is being continually evaluated.


John Shepley

"Sustainability at a Small Business: Emory Knoll Farms"

Even when a business owner has a clear intention of operating sustainably, when faced with limited resources there are many choices and compromises to be made.  John Shepley walks with you down the path towards sustainability that he and Ed Snodgrass have taken at Emory Knoll Farms; from the initial concept of operating a sustainable business to the realities of social and environmental responsibility, and making a living at the same time.  This case study includes opportunities that were realized and a discussion of why some are yet to be.  Visit the Emory Knoll Farms/Green Roof Plants booth in the North American Expo Pavilion to visit with John to further discuss some of the challenges faced by us all in our quest to operate a sustainable business.


Xianmin Wang

"The Current Situation and Future of Green Roofs in China"

Nowadays, China concerns itself more and more about how to make a better life and how to resolve modern city diseases such as environmental pollution, heat island effects, and increased energy consumption.  Therefore, it began to adopt various skills of vertical planting such as the green roof, living wall, and indoor greening to build an environment encouraging energy savings and low carbon features.  Recently, the construction of green roofs in China has stepped into the lane of fast development with Beijing, Shanghai, Shenzhen, and Chengdu taking the leading roles.  This presentation was shown in Mandarin Chinese with English subtitles.
