We stick to our roots.

Within the first years we started with research in the field of building energy modelling.

Grown into Oxford Passivhaus Institute this quickly developed into project management and software development as lead consultants for the industry.

We are still working successfully with global players in the industry.


Oxford - UK

Our main office is located in central Germany, near Würzburg. The area is called Main-Franken and well known for its river Main and the dry white wine.

As one of the TOP 10 High-Tec locations within Europe we have found a neighborhood with likeminded colleagues, such as the Fraunhofer Institute.

But it is Würzburg connection to the Frankfurt Main airport as well as to the main trainlines and motorways we appreciate.

Winterhausen - Germany

Established in 2010 as Oxford Passivhaus Architects by Dieter Jandausch the small innovative practice ventured due to its 10 years practical Passivhaus and Zero Carbon Building experience into research and training.

With projects across the world we are designing, planning and building the environment for a better future.

As experts with more than 15 years experience in anything building energy related we offer a wide and deep range of services.

In order to share our knowledge we offer on a global level expert training courses and continuing professional development for architects, engineers and organisations.
