Our vision & values —
What drives us
8.2 ist ein unabhängiges Netzwerk von über 40 Ingenieur- und Sachverständigenbüros weltweit, spezialisiert auf Prüfungen, Gutachten und technische Beratung für erneuerbare Energien. Jedes Büro arbeitet eigenständig, ist aber Teil der 8.2 Gruppe – verbunden durch gemeinsame Werte, Wissenstransfer und ein starkes Qualitätsverständnis. Gemeinsam bündeln wir Fachwissen für Wind, Photovoltaik, Speicher, Netzintegration und Green Hydrogen.
Sustainability — responsibility for the future
For us, sustainability is not a buzzword, but a central position with which we assume responsibility for future generations. We are actively committed to developing sustainable solutions that protect our environment, conserve resources and strengthen society. In this way, we work with you to create a future worth living in.

About us
Our values and vision
Our vision is a world in which, thanks to the highest quality standards and profound expertise, renewable energy forms the backbone of a sustainable energy supply in order to actively counteract climate change.
To achieve this vision, we support you with independent, highly qualified advice, testing and certification of your projects in the areas of wind energy, photovoltaics, storage technologies and grid integration.
In doing so, we consistently focus on transparency, integrity and innovative solutions. Together with you, we want to maximize the quality and performance of your systems and effectively drive the energy revolution forward — for a livable and sustainable future.
8.2 Geschichte
Establishment of the 8.2 engineering office in Süderdeich
It all began with the founding of the 8.2 engineering office in Süderdeich by Manfred Lührs on October 2, 1995. The company name was copied from the hexagonal screws with information about the material embossed on their heads. For wind turbines, the most common are 8.8, 10.9 and 12.9.
“8.2 doesn't exist, but 8 and 2 are my favorite numbers,” says Manfred Lührs, revealing the secret of finding the name, “back then I didn't just want to found an office for wind energy technology.”
He therefore deliberately chose a logo for the first expert office that should be remembered. 8.2 has since stood for a group of engineering firms, the first of which was founded in 1995 [by Manfred Lührs].
Manfred Lührs becomes first publicly appointed and sworn expert for wind turbines
In January 1997, Manfred Lührs was the first expert for wind turbines to be audited, publicly appointed and sworn in by the Flensburg Chamber of Industry and Commerce.
When Jürgen Holzmüller founded the 8.2 engineering office in Aurich a year later, there was immediate practical benefit. “I no longer had to travel from Dithmarschen to East Frisia because of individual systems,” says Manfred Lührs looking back.
But that is of course an understatement, because the founding of the engineering office in Aurich meant much more — with the creation of this “node,” the structure of the future 8.2 expert network was already apparent.
Development of the 8.2 network
Growth therefore does not occur in one place in an ever-expanding structure, but through cell division and dissemination of new cells across an entire region, ideally across Germany and beyond. This is logical, because a decentralized energy supply includes an equally decentralized service structure.
The founding of the 8.2 Network was therefore actually not a time, but a process that began in 1995 and continues to this day. Manfred Lührs and Jürgen Holzmüller, who still embody and further develop the original idea today, became role models for other wind energy experts who wanted to become self-employed as experts and followed the security of the name 8.2. Because it is a good opportunity for many to become self-employed
Because it is a good opportunity for many to venture into independence because the group can provide “newcomers” with assignments.
In the following years, further 8.2 engineering offices were founded throughout Germany. In the first ten years, a network of 14 engineering and expert offices and two publicly appointed and sworn experts was established.
