Greenroofs & Walls of the World Virtual Summit 2011 Episode 19: Green Roofs Without the Hype Panel Presentation

April 18, 2012 at 12:42 am

Today we have the pleasure to air the “Green Roofs Without the Hype” Panel Presentation with Patrick Carey, Dr. Robert Berghage, Charlie Miller, and Ed Snodgrass from our inaugural 2011 Greenroofs & Walls of the World Virtual Summit on greenroofs.tv and our GreenroofsTV channel on YouTube.

Since Earth Day is coming up, I felt this panel of industry leaders and experts would make a great choice to honor the occasion!

Two of these gentlemen have been long standing editorial contributors to Greenroofs.com – Ed Snodgrass as The Plant Editor (2004) and Patrick Carey as The Architecture Editor since 2005.

Ed’s an accomplished nurseryman, author, proponent of sustainable business practices, and an all around affable guy with a big heart, and writes the (very occasional!) column “Ask Ed.”  We had the pleasure, along with our attendees, of having Ed as one of our Keynote Speakers at our Virtual Summit last September – look for his video “Right Plant, Right Place” coming up soon.  Read my in-depth interview with him at his family farm, Emory Knoll Farms, here.

Speaking of both Earth Day and Ed Snodgrass, make sure you see or record Ed’s appearance on the Martha Stewart Show this Friday, April 20, 2012.  In honor of Earth Day, Martha invited Ed to talk about – what else? greenroofs!

I have known Patrick Carey since 2000, when we corresponded about research and greenroofs (or greenruffs, as he says!).  He is very near and dear to Aramis and me, and is a brilliant (yet mental) philosopher, architectural/greenroof designer, and excellent writer, albeit in a rambling, existential kind of manner.  His column, “A View from the Sky Trenches,” has also come only occasionally, which can be expected of people who have to work for a living instead of writing for us in a consistent manner.  I asked Patrick to lead the panel discussion as the moderator, and in fact he chose the other three panelists to be on his team.

As you know if you read my blog posts, I hold Charlie Miller very dear to me as an inspiration and mentor since I’ve known him for years – I also asked him to be one of our four Keynote Speakers for our 2011 Virtual Summit – you can see my blog post about it here and see the Episode #1 “A New Place” video listed below.

Dr. Bob Berghage is a newer acquaintance, my having met him finally along with the late, wonderful, Dr. Dave Beattie in Nuertingen, Germany in 2004 at the inaugural International Green Roof Congress sponsored by IGRA.  He’s extremely knowledgeable, outspoken, and friendly – a great combo for a professor!

I think the four made an excellent and very smart panel, and I’m sure you’ll agree:

Patrick Carey, GRP, lives in Seattle, WA, USA and has a degree in architecture and is principal of hadj design, a green roof design-build company.  Patrick is also director of the Northwest EcoBuilding Guild’s Green Roof Project and a trainer with Green Roofs for Healthy Cities where he facilitates the Green Roof 101, 201, 301, & 401 Courses.  Patrick is also a contributing editor on Greenroofs.com (2005); he is the Architecture Editor (2005).  He writes an occasional architectural column entitled “A View from the Sky Trenches,” where he selects and discusses pertinent greenroof industry topics.

Patrick was the Moderator for “Green Roofs Without the Hype.”

Dr. Robert Berghage lives in University Park, PA, USA.  Robert D. Berghage, PHD is an Associate Professor in Horticulture and Director of the Center for Green Roof Research at Penn State.  He has been a member of the Penn State faculty since 1994 and was a member of the Faculty of New Mexico State University from 1989 to 1994.  He received a Ph.D. and MS in Horticulture from Michigan State University and a BS in Botany from the University of Michigan.  He conducts research in phytoremediation and plant growth in modified environments.  Current projects mainly focus on green roofs where Dr. Berghage, along with colleagues in engineering and graduate and undergraduate students have been working to evaluate green roof materials, plants, and systems and to quantify the beneficial functions of green roofs.  He teaches Plant Propagation, Herbaceous Plant Identification and Use, and Eco-roof Technology classes in Horticulture.  He is state Floriculture and Greenhouse Crop Production Extension Specialist and the serves on the Penn State Stormwater Management Advisory Committee.

Charlie Miller, P.E. lives in Philadelphia, PA, USA and is the Principal of Roofmeadow. Charlie Miller has 30 years of experience in projects related to civil and environmental engineering.  In 1997, Charlie formed Roofscapes, Inc. (now Roofmeadow) to introduce green roof technology as a new tool for managing stormwater in urban and developing areas in the United States.  He has written four new ASTM standards that are specifically intended for use by the green roof industry, and is currently at work on the new ASTM Standard Guide for Vegetated Green Roof Systems.  Charlie’s firm provides project delivery services, including feasibility studies, design consulting, preparation of construction documentation, construction management, and long-term maintenance and support for green roof installations.  Projects have included the design and installation of the well-known green roof for Chicago’s City Hall.  Roofscapes, Inc. supports and supervises a national network of landscape contractors that specialize in green roof installation.  It also partners with several national roofing manufacturers in order to offer complete green roof assembly packages.  Over 200 green roofs have been installed by Roofmeadow contractors. Consulting services offered by Roofmeadow focus on providing affordable green roof options for controlling stormwater and nurturing green space in cities.

Edmund Snodgrass lives in Street, MD, USA and is co-owner of Emory Knoll Farms/Green Roof Plants. Edmund Snodgrass started the first green roof nursery in North America and has collaborated on green roof research with colleges and universities.  He is co-owner and president of Emory Knoll Farms Inc.  Ed speaks and lectures widely on green roofs and has presented in England, Australia, New Zealand, Germany, Canada and the US.  In 2009, Ed was the recipient of the Spencer P. Ellis award from the Maryland Chapter of American Society of Landscape Architects and is the 2011 recipient of the G.B. Gunlogson Award from the American Horticultural Society.  Ed is the co-author of Small Green Roofs: Low-Tech Options for Greener Living, 2011; The New American Landscape: Leading Voices on the Future of Sustainable Gardening, 2011; The Green Roof Manual: A Professional Guide to Design, Installation, and Maintenance, 2010; and Green Roof Plants, A Planting and Resource Guide, 2006.

Ed is also a contributing editor on Greenroofs.com (2004): the Plant Editor where he answers reader questions, writes occasional articles, and features seasonal greenroof plants in “Ask Ed.”

The premise of the “Green Roofs Without the Hype” Panel Session is:

Here are four people with the knowledge to speak frankly about the current state of affairs in green roofing.

This panel focuses on the designation and evaluation of expertise, appropriate background and training, roadblocks to research and education, design origination and control, chain of custody issues, installation, and the residential market.

After the panel presentation on the second day of the 2011 Greenroofs & Walls of the World Virtual Summit, Patrick Carey, Dr. Robert Berghage, Charlie Miller, and Ed Snodgrass were available for the live Q & A session; the transcript was available archived for 30 days for participants of the Virtual Summit – unfortunately, we do not have it available now – one of the reasons to participate in 2013’s Virtual Summit!

Note: Due to technical and other difficulties from the second party vendor who filmed our illustrious panel of four, this video does not have our standard 2011 Greenroofs & Walls of the World Virtual Summit branding, including the shots from Google Earth.

Project of the Week

–  Our project of the week is the  Green Wall Ferrara, built in 2009 in Ferrara, Italy. This project entailed converting a garden space in the courtyard of a private estate and there was little room for a traditional garden, which led the designers to plant on the walls.  The Optigreen Living Wall Garden system was installed and a beautiful vertical garden was created, resulting in a very soothing effect.

The core unit of the Optigreen Wall Garden system solution is a high-grade, substrate-filled aluminum cassette system which can be planted on site.  The horizontal suspension rails support the Wall Garden elements which are hooked into the rails. The irrigation system is fully automatic with a blending unit for fertilizer and herbicides. Three thousand plants with about 50 different species were planted into this 5 meter high, 120 meter squared private green wall.

– “In the News“

–  Matthew Camp of The Alestle, talks about “Unseen green grows on SIUE rooftops.”  He says several buildings at the Southern Illinois University Edwardsville are becoming a part of a greener tomorrow with the additions of rooftop gardens.  Civil engineering professor and acting environmental program coordinator, Susan Morgan, says there are currently three buildings on campus that have the gardens and there are several more planned for the future.  Biology professor Dr. Bill Retzlaff [one of our contributing editors] says the typical green roof may cost $11-50 per square foot, SIUE’s gardens are at the cheaper end, and “since 2004, more than 100 students have worked on the project.  SIUE is a leader in green roof research in the United States.  They are one of the five or six bigger institutions that conduct research on green roofs.”

Mechanical engineering professor Serdar Celik says they don’t use traditional soil for the roofs – they have been experimenting with different inorganic rocks and different varieties of sedum, and also that the students do experimental testing and theoretical analysis.  They take temperature readings, measurements of stormwater runoff weight, solar radiation, plant coverage, and more.  Celik also says that since we are aware of the global warming issue, the rooftop gardens are one of the solutions toward environmentally friendly sustainable design standards.

– Sandy Bauers of the Philadelphia Inquirer, reports on “Philadelphia embarks on green stormwater management.”  The U.S. Environmental Protection Agency gave the go-ahead to Philadelphia’s $2 billion plan to manage its stormwater with green methods like porous pavements, green roofs, and planting more trees.  EPA Administrator Lisa Jackson said “the city has earned a place as a national and global leader on sustainable innovation and clean water protection.”  She joined Mayor Nutter and other officials at the Fairmount Water Works to sign the agreement for a 25-year plan that has been described as one of the most innovative and ambitious in the nation, it will transform how the city looks but more importantly how the city handles its stormwater.

Other cities like Syracuse, Cleveland and New York will be following in Philadelphia’s footsteps, and hopefully they’re the first of many cities around our country to enhance their cities and beautify their streets.  Later this month, a nonprofit water sustainability organization, the Clean Water America Alliance, will name Philadelphia one of the six national 2012 prize winners for its stormwater plan.

Greenroofs & Walls of the World™ Virtual Summit 2011 Episode 18: Combining Green Roofs with Photovoltaics

April 11, 2012 at 5:19 pm

Today we have the pleasure to air Roland Appl’s video presentation “Combining Green Roofs with Photovoltaics” from our inaugural  2011 Greenroofs & Walls of the World™ Virtual Summit on greenroofs.tv and our GreenroofsTV channel on YouTube.

Aramis and I first met Roland in Nürtingen, Germany in 2004 at the inaugural International Green Roof Congress sponsored by IGRA – the International Green Roof Association.  What a first class person and a first class event!  After the conference, the native German was our amiable and knowledgeable Green Roof Tour leader who took our large group to several beautiful sites around  Nürtingen and  Unterensingen.

One was the awesome ZinCo International Headquarters with about 12 expansive extensive greenroofs, above, and one beautiful intensive greenroof, below, on site used for hosting visitor and employee gatherings.  The premises was later used as testing grounds for developing their solar system used in conjunction with vegetated roofs.

Another stop, included in Roland’s video, is  ZinCo’s first project combining the two green technologies of greenroofs and photovoltaics – the Schule Unterensingen, below, where 200 solar panels and an extensive greenroof grace the top roof of this large primary school in Unterensingen.  Read more in my previous Sky Gardens column about the 2004  International Green Roof Congress  here.

By the way, both  ZinCo GmbH and ZinCo USA have been steady advertising supporters of Greenroofs.com since 2003, and  ZinCo USA is one of our esteemed Sponsors.  We’re grateful for their continued support!

Roland Appl has been working as a green roof engineer for more than 25 years in the Stuttgart region in Germany.  As the Technical Director of the green roof system developer and supplier ZinCo, he has been involved in several technical innovations (e.g. thermally insulating green roofs, green roofs and photovoltaics).  He is designing green roof systems dedicated to all kind of possible applications.  Roland is member of the research group “Green Roofs” of the FLL and he was also speaker at the GRHC conferences in Boston, Minneapolis, Baltimore and Toronto.

In 2009 Roland Appl was elected president of the International Green Roof Association ( IGRA), which was responsible for the “International Green Roof Congress 2009 “Bringing Nature Back to Town” in Nürtingen  near Stuttgart.  IGRA was also one of the organisers of the Skyrise Greenery Conference 2010 in Singapore (read my blog post about it here).

In Roland’s presentation, he explains how the synergistic effects of combining green roofs with photovoltaics are not limited to their installation – the substrate serves as ballast against wind-uplift and 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.

Project of the Week

–  Our project of the week is the Salmon Creek School & Environmental Center, built in 2009 in Freestone, California.  This LEED ® Platinum certified school is the first public school in California to receive this highest level of LEED ® certification.  The educational building is also a community and environmental education center that focuses itself on place-based learning and developing eco-literacy among its students and parents.  SYMBIOS eco-tecture worked with students, administrators, community and environmental groups to design and plan a living roof that would be educational and functional.  The cafeteria food comes from the organic garden; the walls are not only natural plaster but also clean the air; and natural light is strategically introduced to keep the kids perky and to help heat the building in the winter.

In the summer the green living roof keeps the school cool, in the winter keeps it warm and creates a habitat for wildlife all year long.  Biodiversity was emphasized in the planting scheme of the greenroof, which included 12 species of drought-tolerant succulents, three of which are native to California.  Salmon Creek that runs through the school’s property is currently undergoing a multi-year restoration project to restore the Coho Salmon populations and therefore a net zero stormwater discharge rate was mandated.  Other sustainable features of the building include passive solar design, daylight harvesting, a 30 kilowatt PV solar system, eco-plasters and floor finishes, reclaimed lumber and recycled content steel framing low-water use fixtures, and more.

– “In the News“

–  Peter Raabe of the American Rivers Blog, has “A Vision Of Green Roofs In Durham, NC.”  He says “North Carolina has a stormwater problem.”  Many of its rivers are polluted due to stormwater runoff.  The state has put rules into effect to clean up its act and Durham is at the center, on one side, Jordan Lake and the other, Falls Lake reservoirs, and both have strict clean up requirements due to the poor land use practices around them.

Beyond stormwater runoff reductions, greenroofs could offer many benefits to Durham like reducing roofing maintenance, improving building energy efficiency, reducing urban heat island effect, improving habitat for wildlife, improving air quality and the potential creation of a green economy work force.  American Rivers has partnered with Downtown Durham, Inc. and they put on a forum for more than fifty city and business leaders that explored the potential of greenroof enhancements in Durham.  The forum created momentum within Durham and they are on their way to creating a more sustainable city.

– Texas A&M University talks about “Interdisciplinary green roof effort to engage wide variety of students.”  Next fall, 1,000 students from a variety of academic programs, including architecture, construction science, environmental geosciences, environmental studies, landscape architecture, horticulture and meteorology at Texas A&M, will begin working together on an interdisciplinary, three-year project to install and monitor a greenroof and living wall atop a campus building.  Assistant professor of landscape architecture and leader of this project,   Texas A&M University  , says this initiative is aimed at preparing students to become leaders in energy conservation and resource management.

In the project’s first year, students will have learning experiences beyond a traditional classroom setting, as they build, install and maintain all of the elements of the greenroof, including physical structures, standard meteorological and soil monitoring instrumentation, planning and plant maintenance, manual measurement and associated live and stored data processing and display.  This project is funded by a $100,000 Texas A&M reallocation grant for enhancing students’ preparation for the workplace and society through high-impact learning experiences.
