Guided Tour Heliotrope

The Heliotrope was the first Plusenergy House worldwide – a quantum leap in solar architecture. The spectacular building rotates with the sun. Mr. Disch’s office provides guided tours about the concept, construction and technology of the house – including a visit inside. The details of the tour are as follows:

  • Structural design and the rotation mechanism
  • Energy concept and the building insulation
  • Supply of heat, hot water and electricity
  • Solar energy, low-temperature-radiant heating, ventilation, heat recovery and earth-to-air heat exchanger
  • Utilization of rainwater
  • Dry composting unit and gray water treatment

… and what it is like to live in a rotating building

More Options

You want to combine our guided tours with a visit to the famous Quartier Vauban (of which the Solar Settlement is a part) or other sustainable projects in the Green City Freiburg? We ourselves offer only guided tours to our own projects, but we can arrange a competent external guide for the other spots you might want to experience in Green City Freiburg.

For small groups of up to five people, we can try to arrange a visit of one of the inhabitants and homeowners of the Solar Settlement.

Are you interested in our current projects and the further development of the Plusenergy concept? We could offer you a presentation after the guided tour. You wish an exchange of experience with our architects, want to talk to us about your own planned project? You want to talk to Rolf Disch personally?

Anything else? Just ask and we will try to arrange it and make you an offer.
