ABOUT GREEN ROOF TECHNOLOGY

Green Roof Mission - tradition, heritage

Philosophy - Green Roof Mission

Our aim is to provide our clients with dependable and high-quality expertise. With Jörg Breuning's unmatched experience at Green Roof Technology, our ethical and affordable services start delivering benefits immediately.

We strongly think that being environmentally responsible shouldn't be something only a few can afford. Implementing green practices and infrastructure can lead to better returns for everyone in society. Making a real impact needs teamwork, and if we allocate just 10% of construction funds to sustainable solutions, it could greatly enhance both the economy and overall quality of life for everyone.

Jörg Breuning: "I have more than 45 years of experience in Green Roof solutions and Green Infrastructure, and I've seen a lot over the years - if not all.

My mission and values might not align with those who are only interested in quick profits. Instead of exploiting others, I believe in collaborating for the benefit of everyone. From the planning phase to the final execution, I know that trust leads to better outcomes. The best partnerships are those that think about future generations, aim for excellence, and create a positive legacy."

We love to work with you on your Green Infrastructure project!

Green Roof mission and Green Infrastructure
 

History

Jörg Breuning stands out as a pioneer in the modern Green Roof industry, having significantly influenced its development in Europe and Germany over 45 years ago.

In 1999, he brought the idea of Green Roofs to North America through his company, Green Roof Technology. This initiative has established Green Roof Technology as a foundational entity in the U.S., North America, Caribbean, and Middle East Green Roof movement, with a legacy of over four and half decades dedicated to ecological innovation.

Leadership

We are committed to our leadership role in the industry, having played a pivotal role in founding organizations like Green Roofs for Healthy Cities (GRHC) and developing Green Roof standards (ASTM). Additionally, we have assisted numerous Americans in launching successful careers within this field. Ultimately, Mr. Breuning has significantly influenced many of the most recognized figures in the North American Green Roof industry.

Science

Jörg Breuning exemplifies dependable, resilient, and lasting scientific research, contrasting sharply with superficial reductionist studies that seek questionable accolades or temporary fame. His deep expertise, paired with significant global experience and hands-on skills, underpins the foundation of his seminars, workshops, and academic presentations.

Green Roof Technology provides crucial elements for sustainable design, champions environmentally friendly solutions, and endorses Cradle to Cradle principles across North America, enabling the implementation of innovations at multiple levels. The company prioritizes practical assistance and vital resources over fleeting trends.
