Solar panels, also known as PV elements, feel as snug as a bug in the rug on extensive green roofs.

In summer the low growing and diverse blanket of green roof plants are like small air conditioners for the heat sensitive PV elements. At the same time these plants will retain more than 50% of the annual rainfall preventing it from running off into our already stressed sewer systems and waterways.

Compared to gravel roofs, reflective roofs, black tar roofs or metal roofs the cooling effect of modern green roof technology is much more advanced because the water stored in the plant and media system generates efficient cooling simply by evaporation. As a result the PV elements produce more reliable power during high summer temperatures.

Green roofs also reduce air born pollutants and dust drifts found on bare roofs. Less dirt on the photovoltaic panels equals better performance and less maintenance.

Green Roof Technology has developed advanced systems that allow easy and efficient installation of both systems without roof penetration or potential leaks of the roof. Furthermore our design and engineering solutions consider different growing conditions for the plants when combined with solar panels.  By addressing the needs of both solar and plant system in our design we maximum potential for evaporation.

Reduce the environmental foot print of your building and reduce your electric bill at the same time.  Having a combined solar and green roof is the best investment you can make for you and the environment.

BALTIMORE, MD. – Tucked into Baltimore’s eastern warehouse district something new is growing. Lead by Green Roof Service and ADI Architecture and Design Inc. the former icehouse of Resource Conservation Technology welcomed one of the regions first Honey Bee oriented green roofs.

Volunteers and honey bee enthusiast poured onto roof to be apart of the new habitat for honey bees. On lookers explored the garden as volunteers eagerly planted in the unique growing media.

“One of the greatest threats to honey bee populations today is the destruction of habitat due to urban sprawl,” says Diane Odell (ADI), bee keeper and the garden’s designer. To help remedy this, the honey bee green roof features 5,500 square feet of honey bee habitat complete with a small hive provided by State Beekeeper Oliver Snyder III.

Below the rooftop activities, Peter Normandt entertained visitors with information on bee keeping as they enjoyed a bountiful array of honey based snacks.

To make the rooftop garden possible, special engineering and the use of modern green roof technology was needed. “The end result is a light weight vegetated structure that slows and contains contaminated storm-water reducing runoff, reduces air-borne pollutants, protects the roof from damaging UV rays, and better insulates the roof reducing heating and cooling,” says Kat Harrold, accredited Green Roof Professional.

Another benefit the green roof structure provides which makes the bee garden possible is a cooler roof environment. “As water travels through the growing media, roots, and exits through the leaves it creates a cooling effect much like when one sweats. On a sunny day this can reduce the air temperature on the roof by about 10 F degrees,” says Jorg Breuning of 30 year green roof designer and owner of Green Roof Service.

The plants that compose the honey bee garden consisted of a wide variety of flowering plants ranging from bulbs to small trees. The specially selected vegetation provides continuous bloom from February till November.

“The installation was a great success,” commented Diane Odell. “I can’t wait for the spring when everything has been established and starts to bloom.”

Green Roof Expert with 30 years of experience in working on green roofs.

Jörg Breuning works as one of the two owners of Green Roof Service LLC the first company in the United States specializing in professional green roof services. With his business partner Peter M. Philippi they have over 60 years combined green roof experience which is by far unmatched in the United States.

Jorg designed, specified, installed, supervised and monitored more extensive green roofs installations in Europe/Germany than there are currently in the entire USA (2009).


Jorg’s green roof career started in September 1980. In 1983 he announced one of his most important professional achievements. As one the first people in world he achieved his green roof professional accreditation offered by Optima, Dachbegrünungen the world’s leading supplier and manufacture at this time. Optima Dachbegrünungen developed the world first green roof professional education and accreditation system with tremendous success for an entire industry. Their accredited green roof professional education is now essential part of the 3 year landscaping apprenticeship or so called and dual education system for professional in Germany.

Optima Dachbegrünungen and today Optigrün AG continued to educated professional with the latest developments in modern green roof technology. Jörg was studying the technology and with his National certification and technician degree he was also teaching and presenting important aspects of green roofs. He developed many ideas which helped to progress an entire industry and he was part of leading green roof research (i.e. stormwater retentions simulation systems).


Jorg Breuning consulted the nation’s first green roof research program at Penn State University in State College.

He introduced the German FLL guideline (Green Roof Guideline) to the US and systematically helped to make American’s aware of modern green roof technology since 1989. As an independent green roof consultant he provided key information, site supervision and hands on training for many award winning projects like Chicago City Hall, Chicago, IL, Chicago Green Technology Centre, Chicago, IL, Peggy Notebaert Nature Museum, Chicago, IL, Oaklyn Branch Library, Evansville, IN, Heinz 57 Center, Corporate Headquarters, Pittsburgh, PA, Carnegie Mellon University, MV Celebrity Solstice Cruise Ship.


He teaches and lectures at universities, colleges, municipalities, organizations, associations and architects so to speak at Toronto Botanical Garden, New York botanical Garden, GRHC conferences, Sustainable South Bronx New York, The Bronx Overall Economic Development Corporation, Westmoreland Conservation District, Roofscapes Inc. conference, FBB Association, Tecta America Company meeting, Royal Caribbean / Celebrity Cruises, Earth Pledge Foundation, Rotary Club Bel Air, A3C Architects, Lancaster County/City and much more.


Jorg’s knowledge is also incorporated in many brochures, company information, text books and reference books such as Green Roof Handbook RCT, Skyland USA LLC, Cetco Garden Roof Assembly, “Green Roof Plants” by Ed Snodgrass, Germany FLL Guideline, FBB Association, selection of papers on “Tree of Knowledge” at Green Roofs for Healthy Cities North America, at ASTM and SPRI standards.


While having a strong focus on modern green roof technology Jorg’s views, knowledge and expertise is also rooted in many other environmental technologies especially when related to live plants and organisms like, Green Walls, Green Rail Road Tracks, nature swimming pools, advanced composting techniques, solar, wind and alternative energy, recycling opportunities and systems. Most of these German and European based techniques, systems and technologies are decades ahead of most American “green” ideas.


Jorg Breuning certainly understands his world leader ship and being the first green roof experts in the United States of America. He is proud to be mentor and supporter for most of the early key players in the American green roof market including the North American Green Roof Association (GRHC).
