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

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.

SustainableGreenTrendsWorkshop

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

Yesterday morning, Jorg Breuning spoke at the Sustainable Green Trends Workshop at Holiday Inn Midtown, NYC. 

Jorg, along with William Foley of Tremco Inc., presented a 4-hour lecture titled "Planning, Implementing, and Maintaining a Green Roof System for Sustainable Projects."

The presentation explored the many ways green roofs can help develop sustainable design solutions.  Listeners learned how green roofs aid in stormwater management and the compelling reasons to design and implement green roofs in all types of construction environments.  Practical advice, plant selection, the history, and proper detailing of a green roof were covered as well.


Reflective Surfaces on Buildings are an Environmental Nightmare!

Reflective Surfaces on Buildings are an Environmental Nightmare!

 

A new building on London's skyline nicknamed the Walkie Talkie has been blamed for melted car parts due to the intense sunlight reflected from its glass exterior.  In a broadcast for Sky-News (movie) one reporter proves that it is possible to fry an egg in the reflected sunlight.  Developers say they are working to rectify the problem by coating the windows with a less reflective material.  The skyscraper's magnifying glass effect will continue for the next few weeks until the sun's elevation in the sky changes.  

 

Reflecting sun light from building reaches  up to 192°F ! Good to fry eggs.

While white roofs are not  typically curved and are less reflective than the glass clad skyscraper, the physics behind these surfaces are exactly the same. They both are designed to reflect a high amount of the sun light back to the atmosphere.  And by doing so, the reflected sun light has a second chance of being captured by particles in the air, increasing atmospheric temperatures surrounding the buildings.  Certainly London’s Walkie Talkie skyscraper is an extreme example due to the unique shape of the building.  However, it shows very clearly the physics of reflective surfaces, the damage they cause to the surrounding environment and a lot about the lack of common sense of architects, researchers and self-promoted experts.

With this last example, the discussion of high albedo building coverings (above Albedo 0,55) as being environmentally friendly should be at an end.  Governments (e.g. EPA, LEED) should ban reflective surfaces on buildings immediately if they are serious with their environmental programs.  Whether they were blinded by incomplete research, spoiled by the Dollars of manufacturers or simply think they can trick physics,  it does not matter at this point.

Green Roof and Greens Walls (with low albedo) are the better and most advanced choice - naturally.

Recommended: Cools roofs, cool façades are not cool – never have been.
