Single Source - Multiple Problems

Green Team at Green Roof Technology, - Friday, January 10, 2014

By: Jörg Breuning

2013 was another very successful year for green roofs and the green roof industry. However, at Green Roof Service LLC/Green Roof Technology we discovered a trend that might affect the industry in the long run. 

The quality of green roof installations didn't improve as much as the industry grew. We have received more calls about poorly installed or poorly functioning green roofs than ever before. Most of these (green) roofs were installed in the last two to three years and the lack of proper engineering and maintenance has caused issues. These issues are time consuming to fix, require replanting, and the installation of additional growing media or even a permanent irrigation system (even in a wet year like 2013!).

The majority of these under-performing green roofs were under a Single Source Warranty and so our first response was: "Go back to your warranty provider." For green roof owners, this was typically the start of a long odyssey. Odysseus never gave up- but with all the issues presented, my clients were quick to give up because the Single Source Warranties are well-phrased and manufacturers are more likely to argue than take action. Arguing with a piece of paper, written by attorneys, twisted and tweaked by companies' legal departments is an uphill battle. No wonder these numerous stranded people decide to call us.

If the client would have taken his money to the bank, rather than spending it on the warranty (typically $1-$3 per square foot) things could have been much easier and cheaper. On top of that, our costs for designing, engineering and overseeing the installation and maintenance would have saved additional money and no problems to start with.

 

In any construction process we are meticulous with our details, quality of materials, craftsmanship and maintenance. We also offer low bureaucratic, simple and efficient solutions to make your green roof last far beyond three decades. Our green roofs wouldn't need any artificial irrigation, and will prove to not cost as much initially, as well as having the potential to be paid back in less than seven years.

It is our goal for the future to support the growth of the green roof industry (and the plants), one by one making our clients happy. Only happy clients can help us - and the green roofing industry.

Green Roofs in Singapore

Green Team at Green Roof Technology, - Monday, December 23, 2013

By: Samantha Yurek

In Southeast Asia. one island-city is rising above the rest. Singapore has been working on a greening blueprint of the city since 1992. Their ultimate goal: to evolve into a city within a garden! With approximately 272 square miles and 4.6 million people, the biggest challenge faced is space.

 

With 148 acres of vegetated roof space, Singapore has already made it a priority to promote green space. Careful planning has helped to conserve 9% of their total land mass to parks and nature reserves. In 1986, only 36% of Singapore was green space, compared to almost 47% known today.

 

The Parkroyal Hotel, opened earlier this year, is covered in green roofs and walls. Totaling 15,000 square meters of green space all together.

The School of Art, Design and Media at the NanYang Technological University in Singapore sports a curving green roof, giving the building a sleek look. As buildings continue to green, Singapore will grow closer to their goal of becoming a garden with a city nestled inside rather than a city with a few gardens.

Many companies have been involved with the green in of Singapore. To name one, Verditecture LTD, has been in the building and construction industries since 2003. A partner of Optigreen, they have been focusing most of their time on skyrise greenery.

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

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!
