Pioneer & sustainable architecture in Freiburg

Numerous examples of innovative and sustainable architecture have been realized in Freiburg. We present positive energy buildings in an exemplary manner.

The Heliotrop® revolving house is the world’s first positive energy house and was built in 1994 by the visionary Freiburg architect Rolf Disch. This house represents a major step towards environmentally friendly construction. The solar tracker, passive solar energy used optimally and other experimental elements, such as dry toilets and a lagoon system, are presented to you.

Rolf Disch has continued to develop positive energy houses from this laboratory: as part of the development of the Vauban eco-neighborhood, he designed the Solar Settlement with its positive energy semi-detached houses. Part of this project is also a tertiary building, the Solar Ship.

Next, we present Freiburg new municipal administration building, recognized as the biggest plus energy building of Europe. This oval building, whose facades and roof are covered with photovoltaic modules, was designed by star architect Christoph Ingenhoven and inaugurated in 2017. For the city of Freiburg, it is a statement for climate protection: The building produces more energy from regenerative sources than it needs for heating, cooling, ventilation and lighting, thus covering its own energy requirements. Around 800 solar panels on the facade and roof produce electricity, and the excess energy is fed into the grid.
