Because Expertise Matters

In 2002, I was introduced to Jörg Breuning, Green Roof Technology at our first GRHC conference in Chicago. Mr. Breuning was the key consultant of the first Green Roof installed in the United States – at City Hall in Chicago. Mr. Breuning also masterminded the implantation of the green roof at the Peggy Notebeart Nature Museum in Chicago.

I had the opportunity to visit the Nature Museum project with Mr. Breuning, where I came to understand that his knowledge and experience is essential for the entire green roof industry. In 2008 he also introduced the first combined and fully integrated Solar-Green Roof system in North America.

Always Passion

In 2004, I worked on an extensive research paper (European Airport Greenroofs – A Potential Model for North America) and I interviewed Jörg Breuning, Green Roof Technology for the first time. He provided me with essential information, pictures, and leads for this paper. I learned that he was very well connected in the industry and that his own views on Green Roofs were developed over decades of unsurpassed practical and theoretical experience. For him, Green Roofs were never a question – they were always a solution.

Since then, Mr. Breuning has always been my go-to person when I had questions, when I needed concrete facts and information to convince others, or when I simply needed photos for publications or presentations.

Most Importantly Experience

Mr. Jörg Breuning, Green Roof Technology agreed to support Roofmeadow (Roofscapes) on a highly-visible green roof project – the City Hall of Chicago.  Completed in 2000, this award-winning project was one of the first modern green roofs in the United States. Since then, Roofmeadow collaborated with Mr. Breuning on a number of different projects, including the Vancouver Public Library and the GAP.

I truly appreciate having Jörg Breuning taking overall charge of the Gimbles Landmark (Heinz HQ) project.  This is a very high profile project, like Chicago City Hall.  It is a simple design, but it must be done correctly. He also worked with the architect in selecting the plants for the project.

Smart Solutions

I first met Jörg Breuning in 2005 when I attended his green roof presentation at the Maryland Department of Natural Resources in Annapolis.

Although at the time I had been designing and supplying components for green roofs, it was immediately apparent that Jörg’s expertise and experience with lightweight green roofs and advanced green roof components was far superior to that of any other U.S. green roof self-proclaimed experts I knew. Jörg Breuning will continue adding solutions that support ongoing growth for our company, other U.S. green roof businesses, and the green industry as a whole.

In 1999 I was introduce to Jörg Breuning by Charlie Miller (Roofmeadow), the first green roof consultant in North America. Jörg and I immediately connected because of our pragmatic approach on things and certainly because of our passion for succulent plants. I was absorbed by the idea, I learned about green roofs, and instantly knew that this will be starting point of an entire new industry for North America. Jörg's passion motivated me writing my first book - GREEN ROOF PLANTS where he provided most pictures and details.

During a presentation at Celebrity Cruise Line headquarters, Jorg Breuning demonstrated an entirely new and innovative solution to grow real turf grass on the 15th deck of a cruise ship that travels around the world. During this presentation, it was clear that he understood the challenges on high sea, the different climate zones and the potential impact of guests (foot traffic, food spills, etc.).

Mr. Jorg Breuning helped me to jump-start my vision of a green roof project and we were able to convince the City of New York, offering us an empty roof space at the Bronx Supreme Court on 851 Grand Concourse, Bronx, NY 10451. BOEDC hired Green Roof Technology, Jorg Breuning for design, engineering, specifications, and onsite supervision. All steps went very smoothly and finally the green roof was built in 2005 as the first Green Roof on a NYC owned building.

Naturally Skills

Fentress Architect and the NMMC (National Museum of the Marine Corps) hired Jörg Breuning as their key advisor for restoring the existing green roof and the new green roof design at the museum. Together, we finished the NMMC green roof within the budget and within the timeline.

Jörg Breuning has an unprecedented skill set for any type of ground remote vegetation technology or vegetation on extreme locations. His experience far exceeds that normally encountered in the green roof industry - both in the United States and the world.

In early summer 2004, Jorg supported me in starting an own Green Roof installation company (Furbish Co). With the Swarthmore green roof project Jörg Breuning, Green Roof Technology offered an unique opportunity to learn about green roof materials, installation techniques with one week hands-on-training, project logistic, knowledge about green roof plants, and many crucial items related with such a large project. Jörg's skills, enthusiasm, and passion sparked my interest in installing and maintaining green roofs. Today Furbish Company is among the leaders in this field in Maryland and DC area.

I had the pleasure of working with Jorg and Green Roof Technology. Through my own investigations of Green Roofs I have evaluated consultants in the US and Germany. Jorg is by far the most knowledgeable in the industry. A true practitioner, Jorg has more practical experience with Green Roofs than anyone I have come across. At Alcoa Technical Center, we have a small pilot project, which he has been involved with. I highly recommend him for your work.
