Meet Jorg Breuning at ASLA 2013 Annual Expo

Green Team at Green Roof Technology, - Wednesday, November 06, 2013

American Society of Landscape Architects is holding their annual meeting and expo this year in Boston from November 15th until the 18th.  

On Monday, Nov. 18th at 8:00 am, Jorg Breuning and Rob Tilson will hold an education session titled "Solar Panels and Green Roofs Fully Integrated - The Smart Future Development." 

The collaborative presentation between Green Roof Technology and Tilson Group will showcase two of the leaders in the green roof industry pushing the boundaries of their field.  

The benefits of combining green roofs with solar panels is well documented.  The two technologies have been used together for many years, beginning in Germany nearly 30 years ago when both technologies were only first being developed.

Over the decades both technologies have advanced greatly.  Today, fully integrated green roofs with solar panel systems, known as Solar Garden Roofs, have been developed that maximize the two technology's beneficial synergistic effects.  

The Learning Objectives of Jorg and Rob's discussion are as followed:

1) Learn about an integrated technology that combines renewable energy with vegetated roofs, multiplies benefits and significantly reduces cost.
2) Understand the key elements and flow chart evaluation of whether this technology fits a project.
3) Acquire extensive product knowledge including weight, size, potential power output, maintenance, and warranties.
4) Compose proper specifications for construction and define the intersection of the different tasks with lessons learned from past project successes. 

You can take a sneak peak at Jorg's presentation by downloading a pdf on our Resources page -- available here.

Hudson Street Green Wall Completed

Green Team at Green Roof Technology, - Monday, November 04, 2013
2714 Hudson Street in Canton, Baltimore, MD.

2714 Hudson Street's exterior greening was completed today.  The project involved two main components, the green wall and four new tree pits.  

Three large custom-made galvanized steel planters were installed below a Carl Stahl 'Green Cable' System to create the green wall.  Each planter was planted with a variety of perennial vines, shrubs and grasses, including Wisteria, Lonicera, Clematis, Rose and Pennisetum. 

Special thanks to Elemental Metalworks and Flying Colors for their excellent help with the construction of the planters.  

Four large tree pits were dug and planted with Chanticleer Pears.  The soils were replaced with an urban tree pit soil blend from Stancills Inc.

If you happen to be in the area, stop by and let the people at great people at Green and Healthy Homes Initiative know how awesome their new greenery looks.      

One Size Fits All

Or does it?  We're not talking about baseball caps or a pair of mittens here. Green roofs are a living system that on their own should thrive heartily in the environment in which they reside. Not all green roofs are similar, nor should they be. Diverse climates call for various approaches in construction a green roof to handle precipitation efficiently. The vegetation for any green roof should reflect local climate and growing conditions.

Uniform systems will most likely work out fine, but depending on the region, may need constant maintenance to uphold the health of the green roof. At this point, the question is if the green roof is actually doing its job. A green roof is supposed to thrive naturally, as a part of the ecosystem. It defeats the purpose when an irrigation system is put in place or the green roof is over maintained to avoid natural diversity.

Each green roof should be unique in a way that works most efficiently for that particular location. Here at Green Roof Technology we strive to create a living space that will thrive under specific conditions. There should be very little need for additional time, effort and money once a green roof has been put in place.

Designing for Resiliency in an Age of Uncertainty

Green Team at Green Roof Technology, - Tuesday, October 29, 2013

Resiliency was the motto of the 11th Cities Alive conference held in San Francisco last week. With more than 100 speakers, the conference demonstrated once again that modern green roof technology and living architecture are essential to address resiliency by adapting to urban environmental changes and climate change. Large scale extensive green roofs without permanent irrigation or solar garden roofs are the most sustainable solution for reducing the continuously mounting costs of disasters that are weather or climate related.  

The conference disclosed many new details about cutting edge designs and it is now time to see how these can be implemented, how effective and how economical they are. Especially in cities where we created habitats for ourselves with asphalt and concrete. The conference showed refreshing trends for more natural environments. It isn't known whether rooftop farms (urban farming) are a solution, but these efforts create awareness, recreation and educate about living organisms and the importance in reducing food waste.

In different presentations, the combination of solar (PV) and extensive green roofs were marked as the most efficient roof top addition with the highest payback for the owner and the environment. Our solar garden roof fits perfectly into this future trend.

Great conference and great people, thank you GRHC.

Solar Garden Roof Study

Solar Garden Roof Study and ROI

An extensive study about the fully integrated Photovoltaic and Green Roof solution is finally available in English. Green Roof Service LLC / Green Roof Technology performed excellent work that demonstrates all the features of a Solar Garden Roof and Sun-RootTM module.

Successful implemented on European projects over more than 5 years, the Solar Garden Roof can now catch-up in North America. “I am often wondering, why the American market is hesitating in regards of living green innovation,” says Jörg Breuning, "the savings or payback potential of green living technologies is in the US so much higher than in any other country of the world."

It is estimated that Washington, DC alone has a potential of over 2 Million square feet of green roofs combined with PV in the next 24 month. This could reduce the stromwater run-off by over 25 Million Gallons per year and produce over 26 Megawatt hours of electricity in only 12 month. Most of these smart rooftop solutions would actually payback in less than 5 years.

A bare roof with exposed water proofing has no payback.

Interested developer, architects and planners are welcome to visit two demonstrations projects – one in New York, Randal’s Island and another one in the DC area at Prospect Solar.

The system will be also presented at Cities Alive in San Francisco next week.   

Unterm Regenturm: Under the Raintower

Green Team at Green Roof Technology, - Wednesday, October 16, 2013

In 1992 Jörg Breuning, Green Roof Service LLC and Thomas Heuman, Heuman Gartenanlagen provided consulting services to Hundertwasser's architects, Springmann and Associates. It was quite an effort the contemporary artist and the City of Plochingen to develop an entire block of the city's historical district. This city has been around since the year 1146. 

From the outside the historical buildings still remain the same and all facing to an intensive greenroof courtyard in the back. This courtyard and the backside of the buildings received an artists' distinguished signature in 1993. Efficient and gorgeous, the entire courtyard resides on a two story parking garage and grocery store, meanwhile the lush green environment above creates a different feeling. Hundreds of various plants decorate the landscape with paving materials snaking their way through to make perfect paths. The sloped roofs facing the courtyard are also fully or partially greened. Approximately fifty green roofs occupy the colorful, wavy historical buildings.

This particular construction of modern green roof technology underlines the artist's inspirations as well as supports diverse vegetation. The structure is a magnet to tourists and a true landmark of the region for over twenty years and well worth a visit!

Cities Alive Annual Green Roof and Wall Conference

Green Team at Green Roof Technology, - Friday, September 27, 2013

October 23rd to the 26th San Francisco will be alive with Green Roof Professionals. Our very own Jörg Breuning will be featured in a lecture series at the Cities Alive Annual Green Roof and Wall Conference. The topic, Design with Maintenance in Mind, will highlight four sub-topics - one of which Jörg will be explaining the how the Solar Garden Roof System works, specifically highlighting the very first project installed on Randall's Island in New York City.

Cradle to Cradle Concept on a Green Roof

Green Team at Green Roof Technology, - Wednesday, September 25, 2013

"The world will not evolve past its current state of crisis by using
the same thinking that created the situation"  - Albert Einstein


The Cradle to Cradle theory reappeared in 2002 with the release of Cradle to Cradle: Remaking the Way We Make Things by William McDonough and Michael Braungart. A concept dedicated to mimicking nature in which products can be fully recycled. Instead of materials having a specified lifespan, they can indefinitely be transformed into other products. A design created to enrich and benefit the environment even as products are manufactured and used.

Recently, the cradle to cradle design has been proposed for a green roof project in the United Kingdom. By-products from the London Sustainable Industries Park will be collected and transformed into aggregate material used for drainage purposes on green roofs and walkways.

Green Roof Technology has many opportunities to use recycled materials in our projects - as long as the green roof's efficiency isn't compromised or becomes the neighborhood landfill.

Green Roof Pest Control and Maintenance

Green Team at Green Roof Technology, - Tuesday, September 24, 2013

Insects, spiders and other arthropods on green roofs are not uncommon.  Actually, long term studies show that arthropod colonization on green roofs, whether one-story tall or 20-stories tall, mimics ground level colonization, sometimes with even greater diversity.  Arthropods are a vital component for any healthy ecosystem and their diversity in an ecosystem keeps pesky and damaging arthropods in check. 

However, infestations on green roofs do occur.  Last Fall, we helped Swarthmore College diagnose and treat a white grub infestation on one of their green roofs.  By recognizing the infestation signs early, the college’s professional horticulture team was able to control the grub problem through organic pest control methods.

Recently, a red spider mite infestation was reported in a school in the UK with a 12-month old green roof.  The infestation on the green roof was allowed to go unchecked for so long that the bugs made their way into the school via air ducts.  When children began complaining of bites the school had to close down for several days to fumigate.    

Naturally, all green roofs are susceptible to infestation.  Red spider mites are a common household and nursery pest.  Spider mites thrive in hot, dry conditions.  Being aware of their preference for hot, dry conditions and the effect they have on infested plants is vital information all professional green roof maintainers must possess. 

It is important to remind installers that all nursery plants arriving on a project site should be checked for possible disease and pest infestation.  Green roof installers and maintainers must be able to recognize the early signs of infestation and know how to control their populations first through non-chemical methods and finally with a targeted plant-based, non-toxic pesticide if necessary.

New Instant Green Roofs

Green Team at Green Roof Technology, - Tuesday, September 17, 2013

Joe’s Paint Releases: New Instant Green Roofs

Our favorite environmental expert and green roof research specialist Joe is up to his old tricks.  Joe hit the PR circuit again this week releasing a full range of new roof greening products. 

Not satisfied with only offering a green roof in a can, Joe is now offering a full line of instant green roofs.  His new products include a highly reflective white paint for roofs and façades. The can comes with a pair of sun glasses and two cartons of greasy sunscreen (SPF 90) for an entire neighborhood.   

The best green roof and green wall product is already successful on the markets: An artificial grass mat that can be rolled out.  Joe has the fake grass in multiple colors to create Blue Roofs, Brown Roofs and Red Roofs. The good thing is, that after a season you can also fill-up the landfills with toxic waste and contributing your part to a healthy growth of the economy.

 Grass Test

Joe is very excited about the new product line and promises: “Next year we come up with an entire line of fake honeybees, polyethylene spiders and colorful plastic butterflies with remote control. Just before Christmas we will also see artificial flowers and Christmas trees (comes with a fake turkey). “



 All fake grass products are tested under real conditions. 

If you want to walk on grass without having a green roof we recommend the grass Flip-Flops. Retaining almost 100% sweat and you can’t run-off.


We all love Joe here Green Roof Technology because he is constantly pushing the green roof industry and green technologies to new heights.
