Alphabetical Presentation List:


"A Green Building Should Look Green, Which Means Hairy!" Dr. Ken Yeang Keynote Interview by Linda Velazquez (59:00)

The well known architect, ecologist and planner reinvented the high-rise typology as "vertical green urbanism" and is known for his authentic ecology-based work and bioclimatic skyscrapers.  Filmed in mid February, 2015, Linda Velazquez met with Ken Yeang at his London offices and greatly enjoyed his intellect, ecological aesthetic, world philosophy, and sharp wit.

Hear about the early days of the eco-architect - his inspirations, mentors, and use of innovative architectural devices; his progressive body of work including the spectacular Solaris in Singapore and the Kowloon Waterfront masterplan in Hong Kong, among others; his teachings and constant search for higher consciousness; and Ken's hearty advice for today's architects and designers


You will benefit from these 5 Key Learning Objectives as Dr. Ken Yeang shares:

1) His philosophy, ecological design agenda, and specifics regarding architectural devices of the Solaris, National Library of Singapore, and the EDITT Tower (the Ecological Design in the Tropics) among others;

2) How he was influenced early on from studying under Ian McHarg at the University of Pennsylvania;

3) The concept of “ecomimicry” as compared to biomimicry;

4) The biointegration of four ecoinfrastructural armatures of green design in order to be an overall coherent system – involving 4 color codes of green (nature’s utilities, ecology of the land, biodiversity balancing, ecological connectivity); grey (engineering infrastructure including renewable energies, zero energy, net waste, materials); blue (water management including sustainable drainage, closing the loop, rainwater recycling); and red (lifestyles including human infrastructures of material use and regulatory systems);

5) His thoughtful, in-depth advice to graduating or new architects entering our field today and his vision for the future of architecture.


"Biodiversity in the Sky – How Green Roofs Can Be Designed as Wild Life Refuges" Keynote by Dr. Stephan Brenneisen (25:57)

Thanks to green roofs, new ecosystems can be designed to be applied on otherwise barren buildings.  A previously unused space in the sky of cities can host birds, butterflies, bees and other insects – habitats for urban wildlife – while giving us the chance to be close to nature.


Research results show what design principles should be followed to create green roofs as tools to support urban biodiversity.


You will benefit from these 5 Key Learning Objectives as Dr. Stephan Brenneisen shares on the subject of why and how we can design to be very biodiverse, for ecological purposes:

1) What kind of species can benefit from green roofs? Why species need to be mobile or flying, such as spiders, grasshoppers, and snails; learn about his "Green Roof Process-Correlation Model";

2) What kind of ecosystem is a green roof? Reasons why the more growing media substrate (and more water holding capacity) you can give on a greenroof, the greater the opportunities for biodiversity;

3) What kind of green roof design is beneficial for urban wild life? How we need to learn from natural habitats of similar conditions to recreate micro habitats on greenroofs for various animal species;

4) Background: Status of green roofs in Switzerland/Basel based on rare beetle and grasshopper species that have been established on greenroofs and how to encourage these species of wildlife through design measures;

5) Size of greenroofs and metapopulation aspects: How large does the greenroof need to be, how many individuals does a population need to be stable to encourage reproduction of particular species?

"Green Roofs to New Cities" Keynote by Dr. Diana Balmori (9:52)

The big picture is that half of the world lives in cities; it will be 2/3 by 2025.  Cities are major producers of all the things which are feeding climate change.  Green roofs are a simple tool we could us to change this effect, if used at the macroscale.  Green roofs can also play an urban role as open space and as connectors.


Three projects will be discussed: Long Island (Green) City which resulted in the green roofs for Silvercup Studio and Gratz Industries in New York, and Sejong, the new governmental city of South Korea.


Video production by Stacked Up TV Productions. Visuals by Joseph Maida, Mark Dye, Efrain Mendez / archframe.net, Bilbao Ria 2000, University of Iowa, and Balmori Associates with the design teams of each project.


You will benefit from these 5 Key Learning Objectives as Dr. Diana Balmori shares on the subject:

1) Her 2005 research piece/inventory study on Long Island City and how this “Asthma Alley” could affect a direct health-oriented benefit, resulting in greenroofs atop Silvercup Studios and the Gratz Industries Company;

2) How greenroofs have enormous implications playing an urban role as open space and as connectors, creating benefits of a public park without the huge costs of land purchase;

3) How greenroofs are a simple tool we could us to contrast climate change, if used at the macroscale;

4) Her large masterplan with sweeping, continuous greenroofs for the new governmental city Sejong in South Korea introduced the idea of a landscape taking the primordial organizing idea to organize the architecture – based on the previous forms of the mountains and rivers;

5) Why greenroofs are a revolutionary tool at these levels: Building – by altering the relation between landscape and architecture to the benefit of both; City – by reducing the heat island effect; River – by preventing floods and cleaning drainage water; Living Being – by improving our health.

"A Higher Purpose - Benefits to Human Health and Education through Green Roofing" by Elizabeth Hart (23:19)

As we focus on all of the wonderful environmental benefits of green roofs and living walls, the societal benefits are often overlooked - yet humans may be the species with the most to gain.  Research shows that patients who can view nature during recovery have better clinical outcomes, and students that interact with nature during the learning process have improved attention and social skills.  Often the only green space available to these facilities is on the roof and walls.


In this presentation I will highlight research and case studies of green roofs on healthcare and education facilities, including the Providence St. Mary Medical Center green roof above, and the share amazing results of connecting people to nature in an urban setting.


You will benefit from these 5 Key Learning Objectives as Elizabeth Hart shares on the subject:

1) Her ICU Revelation: Green spaces have the power to heal. Learn how the atmosphere of a healthcare facility can truly affect patient outcome and about the numerous opportunities to actively heal environments and people through introduction of vegetation;

2) How her degree in phytoremediation prompted her entrance into greenroofing;

3) Research: Roger Ulrich, PhD studied how the access to nature affects the healing process. Evidence covers 3 measures: Clinical Indicators, Subjective Measures, and Economic Measures – hear the specific, measurable benefits of green spaces;

4) Healthcare has a unique advantage with many opportunities for greenroofs & walls because of how they are built and with so much dead roof space. Why many hospitals are choosing greenroofs: Sustainability: Making hospitals greener; Longevity: Extending the membrane life; Positive market identity with a greenroof;

5) Case studies: Providence St. Mary’s in Walla Walla met sustainability goals and learned what is good for the earth is good for the patient by adding value for the patients, family & staff; hear from the Director of Plant Operations, a former nurse and Chair of Green Team, and a current patient. Edison Language Academy, Los Angeles added 5 greenroofs, 4 accessible: Garden-based learning offers students many advantages. Habitat roof gardens were designed by a school mother and landscape architect – hear from her how kids take lessons outside of the classroom, see cycles of nature, and benefit from vegetative roofs.

"Beyond Extensive and Intensive: Defining the Comprehensive Green Roof" by Molly Meyer (16:10)

The decade-old U.S. green roof market is largely based on German technology.  Advanced understanding has led to breakthroughs that address issues in first-generation green roofs and technology transfer.


Comprehensive green roofs bring the most advantageous qualities of intensive and extensive green roofs together.  Comprehensive green roofs support plant varieties typically seen in intensive green roofs at the depth and weight of extensive green roofs.  First presented at the 2013 Cities Alive Conference.


You will benefit from these 5 Key Learning Objectives as Molly Meyer shares on the subject:

1) Background of authors/designers – Mike Repkin: An ecological designer who studied microbiology and was in the U.S. Army, he is one of the founders of Urban Habitat Chicago and its executive director and co-founded Omni Ecosystem and Rooftop Greenworks; Molly Meyer has been in greenroofing since 2007 while in Germany, building greenroofs for a landscaping company and working for a supplier. Back in the U.S., she designed, installed and maintained all types of German and U.S. systems; formed Omni Ecosystems to fit Mike’s development in growing media with best practices in greenroof technology;

2) Definition of the new design type of comprehensive green roof system: depths; saturated weights; physical, chemical, and biological properties of growing media; plant options; irrigation; maintenance; stormwater retention; and costs;

3) Comparison of comprehensive to extensive, intensive, and semi-intensive green roofs providing technical differences from existing design categories as well as giving further information on its application;

4) Implications of the new umbrella design type offering the best qualities, including both tray & built-in systems. In particular abundant food production in shallower growing media depths is very exciting to promote rooftop farming and increase ROI;

5) Their Vision: How their goal to “democratize greenroofs” by making them more cost effective, biodiverse, and lightweight will benefit everyone.

"Biosolar Roofs" by Nathalie Baumann and Dusty Gedge (19:58)

The Biosolar Roof Project is a Leonardo Transfer of Innovation project that will undertake a series of pilot training projects in partner countries.  The project aims to link the SMART CITES agenda with the Green infrastructure and Ecosystem Services approach to cities.


Solar Energy is a growing part of the smart cities and low carbon approach in the Urban realm.  A key element of the Green Infrastructure and Ecosystem Services Agenda is delivery of biodiversity.  How can high tech solutions (solar) be knitted with low tech solutions (green roofs) to provide not only low carbon energy but also greater provision for biodiversity and specifically pollinators?  Although in Europe green roofs and solar technologies have been combined for many years, all too often the approach has been generic.


The Biosolar Roof Project aims to increase awareness of how the technologies interface and this interface can be positively installed.  In relatively immature markets, errors occur in the specification that can cause issues after installation.  Furthermore, how can good ecological design complement energy production with increased provision for biodiversity?  This is approach is based on techniques and methods developed in Switzerland and implemented in both the UK and CH.


You will benefit from these 5 Key Learning Objectives as Nathalie Baumann and Dusty Gedge share on the subject:

1) Biosolar roof agenda weaves architects, ecologists, and engineers together; the aims of the Biosolar Roof Program include producing a greenroof that will hold solar panels while ensuring the interface also benefits nature conservation and biodiversity, in particular all types of pollinators;

2) How we can successfully combine and link the production of renewable energy (high tech) and the delivery of biodiversity with greenroofs (low tech) in urban areas together with the need to make global policies that are combined for cities to create a win-win situation. European policies are addressed;

3) Case studies of the large green/solar roof on Messe Hall in Basel where colleagues improved the low profile sedum roof with various, specific organic and inorganic elements to increase biodiversity by creating micro habitats; the largest greenroof in Lausanne, Switzerland recently covered in pvs with interesting design features; the London Olympics (2012) Media Centre greenroof which had its own Biodiversity and PV Action Plan and which species the action plan targeted successfully;

4) Ecologists have created a plant list for specific areas of the pv panel: front, back, and underneath for a diversity of plants and habitats of plant associations;

5) Build accredited training programs that will develop workforce skills to install and maintain biosolar roofs; recognize elements of biosolar roof design that have been combined badly, the importance of maintenance, and the need for technicians to have plant knowledge.

"From Passive House to the Cold North—How Vegetative Envelope Components Impact Buildings" Panel with Dr. Bob Cameron, Dr. Allen Lee, Dr. Karen Liu, and Chris Wark (1:05:05)

Moderator Allen Lee, PhD of Cadmus leads the energy panel from Portland, Oregon with Bob Cameron, PhD in University City, Pennsylvania, Karen Liu, PhD in Toronto, and Chris Wark in New York City.


This session will present an examination of the key impacts of green roofs and walls—what they are, how impacts can be predicted, what factors affect performance, and how performance compares to predictions.  The panel discussion will lead to some conclusions about how vegetative envelope components could influence the wider development of residential and commercial buildings based on the Passive House and Zero Net Energy concepts.  Three experts will share their knowledge of these topics through brief presentations followed by a lively discussion.  Bob Cameron brings to the panel information from a study comparing replicate buildings that allowed measurement of the effects of different green building components on energy use, comfort, wastewater treatment, and food growing.  Karen Liu will share her extensive knowledge of the impacts of green roofs and how they depend on climate differences, seasonal variations, and other factors.  Chris Wark will draw upon his broad experience in the analysis of green roofs, development of green roof systems, and systems thinking related to Passive House design.


You will benefit from these 5 Key Learning Objectives as Dr. Bob Cameron, Dr. Allen Lee, Dr. Karen Liu, and Chris Wark share on the subject:

1) Focus on key impacts and economics of greenroof and greenwall vegetative envelope components including energy and stormwater. Identify what they are, how you can predict outcomes, what prediction tools are out there; a look at using greenroof and greenwall crops with biofilters in PA, others greenroof gardens in NYC, Portland, and China where rooftop farming is becoming very popular;

2) How does nature work, from an energy standpoint, using biology in regards to greenroofs and walls? Integrating green building components relative to factors of energy - what kind of media, locations, building geometry, orientation, should people be looking at, i.e. optimizing greenroof to greenwall ratio. What ideas does everyone have for incorporating living green components into buildings? The growth of pvs and greenroofs are discussed;

3) Bob: His multi-year study at the PSU Green Roof Center concentrated on biowalls and greenroofs as a water resource and how these systems could be used to not only clean but also reduce the energy need and concurrently grow crops. Get detailed results on how he achieved EPA's cleanliness standards in less than 24 hours and at the same time reduced both the exterior and interior temperatures of the buildings;

4) Karen: Started in 2000 with the National Resource Council in Ottawa performing multiple tests on various sites in Toronto and Vancouver, BC concentrating on temperature variances between winter and summer on greenroofs and growing media depth differences on water retention and energy savings;

5) Chris: Discussion on performance building concepts of the 90's PassiveHaus movement originating in Dusseldorf, Germany and Net Zero Buildings, how to minimize the amount of energy generated within a small building through correct design and material components and evaluation of lifestyle issues and aesthetics. Green building industry has grown so much in the last 20 years and PassivHaus has matured along the way - can we be doing more? Greenroofs are a promising part of it.

"Greening Rooftops in Alberta: People, Place + Projects" by Kerry Ross (38:32)

While some myths about the suitability of green roofs in Alberta persist given the challenging and extreme climate; that is, long, cold winters, extreme sun paths, a short growing season and low levels of precipitation, this presentation includes a range of case study projects in four of the province’s six main eco-regions.


These projects employ different proprietary systems with distinct expressions and objectives. The characteristics, design intent, plant species selection and maintenance requirements of these case studies are discussed.


You will benefit from these 5 Key Learning Objectives as Kerry Ross shares on the subject:

1) Alberta's very challenging climate conditions of its 4 ecoregions (Banff, Calgary, Edmonton, Stettler) resulting in the need to be irrigating with harvested rainwater. Some of the natural ecosystems are studied (rough fescue grasslands) which could be suitable greenroof candidates evolved to suit the environment to be regionally appropriate; discussions of recent floods; importance of research; her vision;

2) Banff: Case study and lessons learned of: Bison Courtyard at Bear Street - owner wanted an eco-model for the town; McDonough + Partners was the lead and they used their guiding principles, resulting in Alberta's first sustainable mixed-use complex with both extensive and intensive greenroofs in 2004;

3) Calgary: Alberta Ecoroof Initiative, a hands-on research site with 4 different demonstration plots (2004) on the Alastair Ross Technology Centre in the University of Calgary Research Park. The continued collaboration improves understanding of greenroofs in the region, in addition to expanding the plant palette; thermocouple sensors and a climate monitoring station allow studies of the micro-climate impacts and heat flow through the roof. Vegetated Roof Replacement at Calgary Municipal Hall (2014 & 2015) - a highly visible r & d site whose purpose was to draw attention and spark interest in greenroof retrofit projects; organized an education and outreach center; for scientific monitoring, she partnered with Dr. Maureen Connelly's lab at BCIT;

4) Edmonton: Royal Alexandra Hospital, Robbins Pavilion (2011), one of the most northern major cities in North America to incorporate greenroofs. The Ted & Lois Hole Healing Garden is a combination of extensive, semi-intensive, and intensive greenroof gardens, enjoyed by many patient rooms and common areas with diverse vegetation;

5) Stettler: ATCO Electric Service Center's new energy efficient operations center located in an office and industrial complex was designed to enhance customer service (2013). Rainwater is captured on roofs for reuse; numerous challenges are discussed including climate, a broken irrigation system, and plant issues.

"Greening the World Inside and Outside" by Mark Paul (21:12)

Greenwalls can be used to produce instant ‘greenspace’ both inside and out.  These beautiful structures of greenery bring new life and nature back into urban environments.  Just one of the projects included is the Leppington Station, part of a new NSW, Australia, state rail infrastructure project using ecopillows as greenwalls.


We had to satisfy their minimum of 25 + years life expectancy demands. There were 12 x 10 m high strips of varying widths reflecting the market gardening heritage of this outer Sydney suburb that is now undergoing tract housing plus is home to our second international airport.

Over the past couple of years, there have been a growing popularity of greenwalls and green roofs and the move towards green living.  This trend can be seen in both commercial and residential buildings.  Greenwalls provide a number of benefits to the urban environment and numerous case studies are shown.


You will benefit from these 5 Key Learning Objectives as Mark Paul shares on the subject:

1) Our affinity with plants: Learn about his love for plants and holistic approach to site planning, how he started with epiphytes, lithophytes, and others in Rio de Janeiro with amazing plants living on cliff faces, surviving on seasonal rain, inspirations from "Granny Gardens" in Brazil;

2) Appropriate species of plant types and associations found on rocks, granite boulders, sandstone escarpment walls and more from Brazil, Dominican Republic, Sydney, Panama; and the importance of biodiversity and how to encourage and conserve it;

3) Typologies: Photos and discussions of various architectural applications and planting techniques including walls, roofs, balconies, terraces, boats, pocket plantings, and potted plants from Puerto Rico to Panama to China;

4) Many case studies of retrofits including gorgeous wetland and bog greenroof and greenwall projects with fish using recycled water and wastewater for irrigation in Sydney and Queensland and how to create a tiny ecosytstem on a mini scale;

5) In depth case study about a recent 10 sqm greenwall in a fabella in Rio where they collected, processed, planted, and linked 600 PEP bottles participating with school children; a collaboration with Landcare Australia will provide $3000 necessary for funding of future raw material and irrigation systems to allow 400 schools a year to do the same, including in Australia and New Zealand.

"Greenwalls in Middle Earth" by Graham Cleary (7:41)

New Zealand is much lauded for its lush beauty and myriad of natural landscapes from soaring rugged mountaintops to rolling green hills to the glimmering depths of its lakes and seas.


As the setting for both "The Hobbit" and "The Lord of the Rings" movie trilogies, fans enjoyed scenes filmed on both the North and South Islands, hence New Zealand's nickname of "Middle Earth."  This presentation will highlight a few spectacular greenwalls scattered across the island nation.

You will benefit from these 5 Key Learning Objectives as Graham Cleary shares on the subject:

1) Natural Habitats was the New Zealand pioneer in greenroof construction. Learn about their inception, influencers, vision and design philosophy resulting in the potential of landscaping at the highest level with greenroofs in the 1990’s – later turning them on their side with greenwalls; talk about return on investment for developers;

2) Starting in 1994, they constructed the first greenroof in New Zealand with the Quay West Roof Garden in Auckland, enabling Quay West to add an additional four levels of building to its development for spending a little over $100,000 – which equated to an additional $4 million in real estate value; talk about plants and growing media;

3) All native plants were used for the new public 23-square meter greenwall in Civic Square in Wellington with a 2-day installation which was greatly received; many other living wall projects are mentioned;

4) At the exclusive, award-winning development The Parc in Auckland, average inward-facing apartment sales prices were able to be raised by about 25% due to the large semi-intensive greenroof, a private sanctuary with lush landscaping, expansive lawn areas, and pool;

5) The importance of positioning greenroofs and walls in marketing; as an example, he talks about One Central Park in Sydney, setting the benchmark in Australasia. Its branding is huge – leaders want to be associated with something new and green, to set them apart and we can do this smartly and cost effectively with greenroofs and greenwalls.

"Pollinators on the Parapets" by Angie Durhman (25:28)

As natural pollinator habitats continue to decline at alarming rates, we have a responsibility within our industry to design roofs that incorporate "super plants" for pollinators.


This presentation will focus on a new construction project situated in a corn field in Nebraska that covers 2 acres full of plant diversity, and quickly provided a haven for the monarchs.  The talk will also highlight the unique maintenance protocols for this type of roof and provide an overview of plants for pollinators, successful on roofs.


You will benefit from these 5 Key Learning Objectives as Angie Durhman shares on the subject:

1) Definition of pollinators (honeybees, butterflies, native bees, among others) and problems they have been facing over the last few years (such as pathogens, pesticides including neonicotinoids, loss of habitat and more); discussions on a wide range of research; irrigation;

2) Pollinator needs are identified and just a few are nesting sites, clean water sources, and pollinator sources; native bee flight categories; expanding corridors;

3) Evaluation of desired plant species, native as opposed to cultivated, and cultivars' morphology ; a large selection of specific plants are cited; texture; source from neonicotinoid-free nurseries;

4) How to design greenroofs to encourage pollinators on the roof; asking for more structural dead load capacity early on to accommodate greater growing media depths; discussion on the importance of maintenance plans; ask for a greater design palette than just succulents;

5) In-depth case study: Over 2 acres of semi-intensive greenroofs on two areas on a building outside of Omaha, Nebraska in an agricultural community; roof plan; build up of material layers; bermed areas; had 70 lbs of dead load to play with; tight construction schedule; seeded (coverage for long & short term) and hand strewn sedum cuttings, plugs, natives, forbs and grasses; irrigation system; bees are loving the blazing star, and Monarch larvae are eating the milkweed; weed issues and discussion; maintenance.

"Small Scale Green Roofs" by Dusty Gedge and John Little (30:55)

With over 34 years combined experience of building green roofs, John and Dusty will discuss the opportunities of greening up small roofs both old and new.  Having written extensively on this both in print and online, their work provides an inspiration for individuals who want to make a contribution themselves and also for small building and landscape contractors who don't yet have the confidence.


Their talk also looks at why a number of examples of green roofs and how to do them simply and effectively for biodiversity and the wider ecosystem services agenda.


You will benefit from these 5 Key Learning Objectives as Dusty Gedge and John Little share on the subject:

1) How their varied, self-trained backgrounds led them to a love of birds, plants, ecology, green infrastructure at ground level like rain gardens and low-impact living roofs; hands-on experience and the reevaluation of their greenroofs 5-10 years later to judge their success have informed their practices; now using shipping containers used 10-15 years at sea; work on social housing greenspace;

2) Sharing information led to the minutely detailed small green roofs guide (2005 and then 2014 for the web-based guide), providing advice and confidence for DIYers, and the workshops which allow for the very gratifying interaction with people;

3) Different aesthetics of natural roofs; whatever you do to the soil will determine the plant community so play around with soils found on site, what nutrient level is best to make it more biodiverse;

4) Up on John’s greenroof they discuss plants, soils, and more; advice on how to get water off your roof in a reasonable speed; vegetation must be right for each person; edge details; local, regional materials; native herbs;

5) How can we integrate animal biodiversity more for invertebrates, pollinators, and others? They always put in habitat walls, bird boxes, mammal boxes, etc., for breeding spaces; how this principle from small scale habitat greenroofs can be taken to the large scale.

"Social Healing with Greening" Panel - Part 1 with Patrick Carey, Peter Ensign, and George Irwin (1:18:08)

Moderator Patrick Carey leads this panel from Chicago, Illinois joined by Peter Ensign in Washington, DC, and George Irwin in Rochester, New York.


The idea of ecology is not limited to stormwater runoff and saving energy.  It also includes how we relate to each other, how imbalances are addressed - no less so than in the natural environment.  In this hour panelists experienced in working with issues of human ecology like unemployment, poverty, and rehabilitation through projects that also heal the natural environment, will share their experiences and perspectives.


You will benefit from these 5 Key Learning Objectives as Patrick Carey, Peter Ensign, and George Irwin share on the subject:

1) Learn about the numerous benefits to the green economy when including greenroofs and greenwalls and with different training programs how people - at risk youth, underprivileged adults or transitioning adults - can turn their lives around and heal themselves and the environment. What are the social benefits to these programs? Why is it important to have some classroom component, internship and field skills for a trained workforce;

2) Peter Ensign: For 21 years DC Greenworks has been working in the green and green infrastructure industry with schools in underserved neighborhoods, creating demonstration projects including greenroofs, rain gardens, rain barrels, conservation landscaping, etc., moving from installation to training and workforce development and now greenroof maintenance;

3) George Irwin: He stepped down as CEO (now president) of Green Living Technologies to focus on vertical farming and educational programming: learning by doing, hands-on; edibles equal renewables which creates jobs. 3200 people have come through their training, with education in 13 countries plus across the U.S. Their pilot classroom in the Bronx was at Discovery High which went from 43 - 93% attendance to 100% attendance rates for four years in a row;

4) What are the benefits and limitations of - and how they work - incentives and mandates from a public or non-profit perspective versus how the private sector operates around the independent contractor. The blending of the public and private;

5) Patrick Carey: What promises and nightmares do you see on the horizon for the social productivity of what you're doing, in terms of the theme of the panel - the transition between education and work experience?

"Social Healing with Greening" Panel - Part 2 with Patrick Carey and Darius Jones (30:36)

Moderator Patrick Carey follows the "Social Healing with Greening" Panel - Part 1 with Darius Jones in Chicago.


In Panel #1 you will hear from the perspective of industry (George Irwin of Green Living Technologies International) and non-profit (Peter Ensign of DC Greenworks).  In Panel #2 Patrick Carey speaks with Darius Jones, who participated in some of the very social programs discussed in Part 1 for his viewpoints.  Now working with the Chicago Botanic Garden and the McCormick Place Rooftop Farm, he had previously served a five-month sentence in the Vocational Rehabilitation Impact Center's garden program in 2010 and then enrolled in the nine-month Windy City Harvest Apprenticeship program.

You will benefit from these 5 Key Learning Objectives as Patrick Carey and Darius Jones share on the subject:

1) Learn about the life consequences growing up in the west Garfield Park neighborhood of Chicago which resulted in Darius' incarceration, his struggles and influences for rehabilitation in Cook County’s Vocational Rehabilitation Impact Center, enrollment in the nine-month Windy City Harvest Apprenticeship program concentrating on sustainable urban agriculture, and his transition to the Chicago Botanic Garden and promotion to the McCormick Rooftop Farm;

2) Hear about Darius' experience with the pros and cons of the Windy City Harvest Apprenticeship program, mentoring support and technical assistance and skills learned, his introduction to a now professed lifelong love of plants and growing them, and how it has opened up a world of possibilities and opportunities;

3) He shares his experience as the manager of the McCormick Rooftop Farm, a half-acre food production farm currently growing 17 crops with beehives and indoor hydroponics; his additional opportunities as an incubator farmer with Urban Aggies, a sustainable urban agriculture business he started in 2013 - with 90 square feet of private growing space where he makes and sells pestos, vinaigrettes with herbs, salsas, and more;

4) How the local community benefits from Windy City Harvest, with food going to shelters, WIC programs, farmers' markets; his experience of how it has affected low income families - getting fresh food from nearby and learning to cook more healthily;

5) Patrick asks where does Darius see himself in the future, in 3, 5, 10 years? Continuing in food industry as an entrepreneur, even 20-30 years down the road, and public speaking about his experiences.

"Soil Ecological Processes on Green Roofs: Research and Observation Meet Theory and Intuition" Inspiration Nook video by Christine Thuring (3:33)

This brief talk ruminates on incidental results from Christine's ecological surveys of some of the oldest extensive green roofs in Germany.  Earthworms and ant colonies were encountered in sufficient numbers during soil sampling to suggest that their presence in green roof substrates is not entirely uncommon.


With reference to terrestrial soil ecosystems, Christine reflects on this unexpected aspect of green roof soil ecology and contemplates how the presence of such ecosystem engineers could change our treatment of extensive green roofs.

You will benefit from these 5 Key Learning Objectives as Christine Thuring shares on the subject:

1) Theory versus practice: theoretically, greenroofs can function as both green infrastructure and green ecosystem but our knowledge of engineered systems far exceeds that of ecological systems, or long term performance;

2) Through her vegetation surveys and soil samples on 9 of the oldest extensive greenroofs in southwest Germany she made incidental observations regarding the presence of earthworms and ant colonies;

3) Soil is fundamental to life and to 'ecosystem services'; green wash can be ruled out through knowledge;

4) Long-term monitoring is a weak point for most forms of ecological research and there is much to learn, especially for long-term processes;

5) Biodiversity is the keystone to ecosystem function and services, an emerging point of conviction from urban ecology which greenroofs could adopt.

"Stewardship of Rooftop Ecosystems" by Michael Furbish, Brad Garner, and Dr. Whitney Griffin (23:06)

Selection of a green roof system and initial green roof planting set the stage for the ultimate end goal of any green roof: a healthy and reliable rooftop ecology.


Explore the changes that green roofs experience as they grow and evolve, and learn about strategies to guide green roofs toward healthy maturation.  See examples of successes, challenges, changes, and constants.


You will benefit from these 5 Key Learning Objectives as Michael Furbish, Brad Garner, and Dr. Whitney Griffin share on the subject:

1) Definition of stewardship; understand how a greenroof is a living machine, an evolving ecology, and that change is the only constant; over time a greenroof will change at the microbial, chemical, and physical levels;

2) Definitions of success; see how the selection of a greenroof system and initial greenroof planting set the stage for the ultimate end goal of any greenroof: a healthy and reliable rooftop ecology; welcoming diversity;

3) Learn about strategies to guide greenroofs toward healthy maturation with full coverage and viable plant health at various depths; irrigation;

4) See examples of successes, challenges, changes, and constants with case studies of Capital One in Tysons Corner, VA; PECO in Philadelphia, PA; Park Place in Annapolis, MD; Regency Housing and Sidwell Friends School in Washington, DC; private residence in Virginia; and DC Water's Ft. Reno Reservoir;

5) Design intent is just a starting point; volunteers; managing owner expectations; diversity management.

"The Development of Revolutionary Large Scale Vegetated Infrastructure Projects in Latin America and the Foundation of a New Industry" by Pablo Atuesta (38:20)

Latin America has quickly become a hot spot for sustainable design with many examples of living roofs and walls through Central and South America and the Caribbean.


Pablo Atuesta from Groncol, a Colombian company with over 180 projects and more than 150,000 square meters of vegetated infrastructure, will show us some extraordinary projects in this geographically varied region, including the 92-meter high greenwall on the Edificio Green in Medellin, Colombia as well as greenroofs like the one atop Connecta, left.

You will benefit from these 5 Key Learning Objectives as Pablo Atuesta shares on the

1) Pablo says fell in love with regenerating the environment and that we have the power within the industry to change the world. Greenroofs made sense addressing the triple bottom line of a company: environmental, social, and economic benefits; lots of research and development to reach the level of products they have;

2) Latin American growth is disorganized, informal, with health problems such as kids dying due to air pollution - not enough trees. Learn about their developments within the last five years and future goals - Colombia wants to get to 13,000,000 m2 of planted roofs and walls like Germany;

3) LEED is a big driver here accounting for 11% of construction licenses looking for certification and the Colombian Green Building Council is a large influencer;

4) See numerous examples of gorgeous projects including vegetated roofs and walls for several private residences, corporate headquarters, shopping malls, hotels, schools, and medical facilities/healthcare companies in Bogota, Medellin, and Armenia, among other cities. In particular these standouts highlight the Colombian efforts: the massive greenroofed Connecta complex, the 92-meter high Edificio Green greenwall, the Los Andes University greenwall, the Gaia B-3 Hotel's living wall which became an icon in the city of Bogota, and the current Santalaia in Bogota which will have 2,800 m2 of greenwalls (2nd largest in the world) with a complex irrigation system - the smart building has a water treatment plant to reuse 100% of water;

5) Groncol and industry partners have developed and actively supported the growth of the Colombian vegetated infrastructure guild Recive and created new suppliers like Metroverde, a nursery, with local companies. As a result, the World Green Infrastructure Congress 2016 will be held in Bogota; watch the 2-minute promo video for the WGIC in 2016.

"The Great Green Roof Review: Success & Succession" by Jenny Hill and Terry McGlade (31:04)

A retrospective, comprising several of the oldest roofs in North America will be presented to provide a framework within which to consider ecological succession as an ultimate end goal of extensive green roofs.  We will consider fundamental issues concerning the post-construction phases of green roof management including the economic and environmental expenses of weeding, fertilization and irrigation of extensive green roofs:

What happens when the manicured aesthetic ideal is rejected either intentionally or through neglect?  What it the long term viability of a green roof as a piece of ecological urban infrastructure versus its survival as a horticultural canvas?  What can we learn from revisiting old projects and how can we design with the evolution of individual sites in mind?


You will benefit from these 5 Key Learning Objectives as Jenny Hill and Terry McGlade share on the subject:

1) Jen and Terry examine 10-year old greenroofs by Terry McGlade of which 5 out of 6 are high compost roofs and 5 out of 6 were not just sedum-only roofs to consider ecological succession as an ultimate end goal of extensive green roofs; a look at the local legislative framework;

2) Examination of the post-construction phases of greenroof management - the succession of management, the classical ecological succession of how they are changing in terms of plants, soils (including compaction, erosion), etc., the change from the original design intent;

3) Six case studies that Jen surveyed over the last two summers (2013 & 2014) are presented: Earth Rangers East School, Ryerson University, Jackman Avenue School, Toronto Botanical Garden, UTSC Arts & Administration Building, and the Royal Ontario Museum;

4) Discussion of examples of "no maintenance greenroofs" - what to expect; the importance of using local native plants; managing client expectations in terms of change over time;

5) In some cases you can go back and revitalize greenroofs to make them healthier - perhaps every 5-10 years we need to do that, look at plant colonies, soils as they are closed systems. Ask yourself, are they still working? We need an ever changing "Green Roofs 2.0" dialogue.

"Two Extremes in Waterwise Design from Denver, Colorado and Athens, Greece" by Andrew Clements and Karla Dakin (35:05)

Both Karla and Andrew have experimented extensively to design vegetated roofs with minimal or no supplemental irrigation in a hot, dry city like Denver or Athens. They both conclude the possibilities exist but the challenges lay in client expectations of what an non-irrigated green roof will look like.


Together they will discuss plant selection, irrigation options and how to convince clients to go dry.


You will benefit from these 5 Key Learning Objectives as Andrew Clements and Karla Dakin share on the subject:

1) Learn about Karla and Andrew's "A Tale of Two Cities" and interest in waterwise greenroofing in the similar arid settings of Denver, Colorado and Athens, Greece and how it informs their design processes;

2) Denver is an arid prairie with 14-16" of precipitation, including snow, per year; arid with harsh extremes, soils are gravelly and rocky with high winds - hard to garden.  Athens is similar to Denver but different as it has earthquakes - but can also snow with sub-zero temperatures with up to 9 months of drought;

3) Examination of the native plant communities they have studied and experimented, offering a multitude of possible plants to select for greenroofs: Karla - the Ponderosa pine ecosystem in the western Rockies, Alpine ecosystems, and the desert areas (succulents, cacti).  Andrew - the dry, rugged garigue ecosystem in Athens with little soil, aromatic herbs, pines, stunted shrubs, and outcrops in the landscape;

4) Climate appropriate plant studies and issues encountered on these projects and others: Colorado - Denver Museum of Contemporary Art, Denver Botanic Gardens, a commercial roof in Denver, residence in Boulder; Athens - restoration of a hotel complex with many 12-year old greenroofs, a high end villa, commercial roof, Ministry of Finance, and a residential roof.  Discussion of their 5 favorite plants to use;

5) Irrigation is a critical factor: options, issues, and strategies in both Denver and Athens; discussion of substrate types and depths; greenroofs can thrive with little or no irrigation after establishment.

"Urban and Social Needs of Green" Inspiration Nook video by Marc Grañén (3:35)

Yes, we have a serious problem, as we haven’t understood what sustainability means.  Fortunately, there are more and more of us, who day by day, are working hard to solve this.  The path is long and hard, but full of shades.  As a landscape artist I always try to capture Nature at what it does best: exist.  And this happens because Nature itself is sustainable, otherwise it would have never existed.


So, I firmly believe we must humbly learn from it.  This is why I can’t stop joining beauty with functionality in my creations: greenroofs everywhere, even on vehicles.  I work in projects to create functional greenwalls that operate as air/water filters, thermal insulators, passive/active cooling-heating systems… And of course, the pedagogical ones, the edible greenwalls at schools -  where I can share amazing projects with the kids, who have become our best hope in a close future.


You will benefit from these 5 Key Learning Objectives as Marc Grañén shares visually on the subject:

1) His influences and early projects;

2) Construction through the various stages of setting up a greenwall system on multiple schools;

3) Symbiotic master classes where he teaches and informs young through teenage school children "It's a kind of magic...to feel the soil under your nails...";

4) Discovering urban biodiversity: Experience the joy of discovery on the children's faces when they touch, plant the different herbs, succulents, and vegetables plus find animals like frogs, earthworms, and birds;

5) Celebrating life: He wants children to experience science and sustainability through education with green, living plants.

"Using a Climate and Ecological Template Approach for Plant Selection for Extensive Green Roofs" by Ed Snodgrass (27:25)

This talk will focus on plant selection using climate types for selection, understanding the difference between a continental and maritime climate, for example, and what that means for plant survival and maintenance.


This talk will also look at plant selection and the promise of the delivery of ecosystem services such as habitat creation or biodiversity.


You will benefit from these 5 Key Learning Objectives as Ed Snodgrass shares on the subject:

1) Plant selection relative to the function of the plants and the geography of the roof location. What do we want from them, what are we asking these plants to do, and what are we asking them not to do on the harsh locations of rooftops;

2) Use not only the USDA Plant Heat Zone and Hardiness Maps but also the World Maps of Köppen-Geiger Climate Classification as they give much more data regarding rainfall and the Grimes Triangle showing the 3 ecological strategies of plants by type: Ruderals, or pioneers, which are disturbance-tolerators; Competitors, which are long term winners; and the Stress-tolerators which can live where nothing else can;

3) Habitat examples with these attributes to visit: the alvar plains in upstate New York, Huntington Botanical Gardens in CA, pioneer thermophyllic herbaceous communities on rock outcroppings in central Europe, Lava Beds National Park in CA;

4) Plants develop different strategies depending on where they live, e.g. removal of chlorophyll, live during the good times only, size; see what's growing on naturally occurring roofs in urban areas - examples from Morocco and China; developing cultivars for greenroofs selected especially for a particular stress;

5) How do we want plants to perform? For example as larval sources, urban beekeeping, stormwater management, highly evapotranspirative, amelioration of atmospheric deposition.  A look at two distinct greenroofs at the University of Melbourne.  Plant specification has gone from really thinking about it to being very casual, so it's time to reenergize some of our scrutiny.


"Versatile Living Walls & Roofs: International Applications for Agriculture, Energy Conservation, Pollution Attenuation, and Aesthetics" by Dr. Bob Cameron (34:56)

Living walls and roofs can be designed to provide functional architecture.  These functions can include the growth of food products, reducing pollutants in air and water, and minimizing building energy use.


Specific research and field applications of these functions from both the USA and China will be described.  Potential pitfalls are also discussed.


You will benefit from these 5 Key Learning Objectives as Bob Cameron shares on the subject:

1) The journey should be just as interesting as the destination: His exciting but daunting teaching at Qingdao Agricultural University in China for a couple of months last year - learn all about this 4-month sojurn including visits to numerous greenroofs and greenwalls some of the issues relating to government ownership;

2) Four examples of what he observed: in India he focused on the "golden triangle" to Delhi and its living walls, an expansive agro production on a roof outside of Shanghai, living walls in Kunming, and living walls and greenroofs in Seoul;

3) Discussions of the various issues regarding living walls and roofs as confronted in India, China, and South Korea - transitional climates, wrong plants, lack of knowledge of greenwall technology, water requirements - underscoring lack of maintenance. For example, at an airport in India the client wanted a lifetime guarantee on their new greenwall but refused to pay for any annual maintenance;

4) Main problem throughout the world is available palette of plants for both interior and exterior living walls, although growing; traveling around Asia, he went to remote areas to look for the potential of plant species to be adapted and brought to the nursery industry including karst topography, limestone formations, Alpine areas, the Gobi Desert including a very biodiverse oasis, and the Holy Mountains;

5) Different drivers: Many case studies including a roof garden outside of Hangzhou from an owner who wanted uncontaminated veggies for his workers utilizing Feng Shui; The Bund in Shanghai with its stunning "flower wall" over 100 ft along constructed for beauty - part of the Chinese philosophy; Kunming in southwest China believe planners and designers' projects should be "harmonious & liveable" with flower walls and wall planters on highways and parking garages allowing facades to be covered in green; the mega project at the Beijing International airport symbolizes a dragon.
