Green Tea 4 Two with Patrick Carey & Jörg Breuning


Proper function and long-term reliability of Green Roofs in North America is increasingly questioned. While there is a flood of new products, and new and more colorful brochures, the quality, healthy driven plants, and simple-solid function of Green Roofs seems further away than ever.

Patrick and Jörg, two Green Roof pioneers with almost 40 years of experience, discuss causes, reasons and potential solutions while enjoying a few cups of Green Tea.

“Green Tea 4 Two with Patrick Carey & Jörg Breuning” promises to be an entertaining, inspirational, and informative discussion between two long time experts of the U.S. greenroofing scene.

Jörg Breuning is the founder and owner of the advisory, engineering, and design firm Green Roof Service LLC / Green Roof Technology.

While continuing to practice his hands‐on education, Jörg attended the University of Hohenheim, Stuttgart, Germany earning his degree in Horticultural Science. In 1985 he started his own company focused on ground remote vegetation, extensive green roofs and the establishment of vegetation on extreme locations. Since then his company has overseen countless projects, introduced many green roof innovations or installation techniques, and received many awards. Jörg was the first expert green roof consultant in the United States and advised in many of the most amazing landmark projects in North American green roof history. His work in the United States began in 1998 when he provided design solutions, construction advice, and hands-on training for the Chicago City Hall green roof project.
