One Size Fits All

Green Team at Green Roof Technology, - Wednesday, October 30, 2013

By: Samantha Yurek

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.

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.

Highlighting Baltimore Green Roofs!

Green Team at Green Roof Technology, - Monday, September 09, 2013

By: Samantha Yurek

With a growing number of green roofs appearing, the city of Baltimore is slowly climbing up the green ladder. I wanted to take some time to highlight a few green roofs located right in our neighborhood. In a dense urban setting, green roofs can play a huge role in sustainability efforts because of their ability to mitigate storm water during large rain events. Urban watersheds are especially vulnerable to environmental issues consequence of a high density of people mixed with large amounts of impervious surface area.

 

 1. Baltimore's National Aquarium


Created to aid the aquarium's conservation efforts, the extensive green roof atop the National Aquarium in Baltimore stretched for 4,000 square feet. Built in 2005 by the Furbish Company, the flourishing roof has been a pleasant addition to the inner harbor.

2.  Hilton Hotel


The largest of them all, at 32,000 square feet would be located on the Hilton Hotel, installed by the Furbish Company in 2008. Adjacent to the Baltimore Convention Center and Camden Yards, the hotel has 757 rooms available. The green roofs reside on both the east and west wings of the building and create additional outdoor green space for citizens to enjoy.

3. Baltimore Convention Center


The Baltimore Convention Center followed in 2010, with the Barrett Company working to install a 15,000 square foot green roof. Doubling as a recreational area, this roof has been transformed into a green oasis in the heart of an urban space.

4. Mary Catherine Bunting Center at Mercy Medical Center


Also in 2010, Mercy Medical Center stepped up and installed three green rooftops to assist with patient health. With 17,500 square feet, these intensive green roofs are also viewed from many of the patient's windows. This project was completed with the help of Mahan Rykiel Associates.

An increase in green space in Baltimore is a fantastic step toward a more sustainable city. Keep up the good work Baltimore!

 

 

Green Roofs Protect Solar Panels and Micro-Inverters

Green Team at Green Roof Technology, - Thursday, September 05, 2013

Randall's Island, NYC.  The Solar Garden Roof System is uniquely designed to grow plants under PV Panels - protecting the panels and microinverters from extreme rooftop heat.  Our system produces more energy and prolongs the life of your solar equipment.  

Over the holiday weekend a massive 11-alarm blaze erupted at the Dietz & Watson distribution center in South Jersey.  The very destructive fire burned for nearly a day due to a peculiar reason - the 300,000 square foot building had more than 7,000 solar panels on its roof.  Instead of being able to tackle the fire from close range, firefighters were forced to fight the fire from a distance in order to avoid any risk of electrocution from the solar panels.  Most solar panel arrays do not have a simple on/off switch, or a master breaker.  So long as the sun is shining, the panels are producing electricity.  Individually, a solar panel does not create enough volts to harm a person, but when solar panels are strung together to a single converter, the power of each panel is accrued, creating a deadly situation for anyone near the array during an emergency situation. 

While no specific forensic evidence has been issued yet, experts in the field of roofing and solar panels already agree that the fire may have started due to the intense heat that is created between low-lying solar panels and reflective white roofing membrane.  Extreme rooftop temperatures can be effectively controlled by installing green roofs below solar panels.  Countless studies have shown that the surface temperature of extensive green roofs rarely exceeds 86°F.  When solar panels and green roofs are integrated, i.e. a Solar Garden Roof System, rooftop and solar panel temperatures are significantly reduced.  Lower rooftop temperatures means greater energy production and may potentially save your building from destruction.
