January 28, 2015 at 2:36 pm

Our colleagues over at IGRA – the International Green Roof Association – have just released their free downloadable 36-page PDF entitled IGRA Guidelines for Green Roofs “Bridging Trades – Safe Section Changeover: Roofing Technology – Vegetation Technology.”


Editors Roland Appl, Wolfgang Ansel, and Sabine Frueh of IGRA say even the best laid greenroof plans can go wrong if the underlying roof is not prepared to meet demands.  This issue lead IGRA to develop the new guidelines, “Bridging Trades – Safe Section Changeover: Roofing Technology – Vegetation Technology”:

“The content of the IGRA Guidelines is made up of two main modules:

– A checklist that provides a clear and concise overview of current examination criteria for the roof and vegetation technology interface.
– A commentary volume that provides further explanations and graphic material of all technical terms and questions in the checklist.

The guideline is not only designed for Green Roof installers and roofers. It is also designed for architects, planners, and developers who can take advantage of the practical and legal references.” ~ IGRA

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 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 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.
