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.

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.   

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.

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.    

 

 

Protection for Honey Bees

Recently making an appearance on the front page of TIME Magazine honey bees are really starting to stir up popular interest.  But why all of the sudden? About a decade ago honey bees started dying off an alarming rates.  This past winter, nearly one third of honey bee colonies in the United States died or disappeared.  In June over 25,000 honey bees were found dead in a Target parking lot in Oregon.  Cause of death: an insecticide which contained neonicotinoids - a topic I covered back in May when the European Union took a stand and banned these killer pesticides.


  
 

Recognition of the significance of this issue is finally surfacing.  Although started back in 2009, National Honey Bee Day was a more popular holiday this year. A grassroots effort by beekeepers and interest groups to promote community awareness on honeybees, this holiday was celebrates this past Saturday August 17th.  The theme this year: "Beekeeping - Ask Me How to Get Started."  Farmer's markets and nature centers among others all over participated, educating the public on honey bees. 

All this commotion about these buzzing little creatures is beginning to pay off. The Environmental Protection Agency has ordered a reduction in the use of widely known pesticides and a change in labeling on pesticides to educate the consumer on the harm to certain pollinators.

Honey bee efforts have been popping up all over the country. These efforts have not only been seen on rural farms, but even on rooftops in the city! One example perched seven floors up, 100,000 honey bees buzz busily, hard at work to keep a Manhattan green roof flourishing. Green roofs are a great place to start an undisturbed honey bee colony. Let's not forget how important these little creatures are in our ecosystem and how essential they are to our food production. Take some time to learn more about the amazing honey bee!

Green Roof Technology doesn't allow the use of herbicides or pesticides on any green roof project since 1980!
