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

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.




30-Minute Live Q & A with Ken Yeang.


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

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.



30-Minute Live Q & A with Stephan Brenneisen.


"Green Roofs to New Cities" Keynote by Dr. Diana Balmori

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, Puerto Triana Development in Seville, Spain and Sejong, the new governmental city of South Korea.




30-Minute Live Q & A with Diana Balmori.

"A Higher Purpose - Benefits to Human Health and Education through Green Roofing" by Elizabeth Hart

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.



30-Minute Live Q & A with Liz Hart.


"Beyond Extensive and Intensive: Defining the Comprehensive Green Roof" by Molly Meyer

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.



30-Minute Live Q & A with Molly Meyer.


"Biosolar Roofs" by Nathalie Baumann and Dusty Gedge

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.



30-Minute Live Q & A with Nathalie Baumann and Dusty Gedge.


"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

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.

"Greening Rooftops in Alberta: People, Place + Projects" by Kerry Ross

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.

"Greening the World Inside and Outside" by Mark Paul

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.  Leppington Station is 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.

"Greenwalls in Middle Earth" by Graham Cleary

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.

"Pollinators on the Parapets" by Angie Durhman

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.

"Social Healing with Greening" Panel with Patrick Carey, Peter Ensign, George Irwin, and Darius Jones

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


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.

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

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.

"The Great Green Roof Review" by Jenny Hill and Terry McGlade

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?
