Plus-Energy House – A House That Generates More Energy Than It Consumes

The smarter E Podcast Episode 163 | January 25, 2024 | Language: German

A house that generates more energy than it consumes. It sounds utopian, but it has long been a reality. Back in 1994, architect Rolf Disch built the world's first energy-plus house. The basic principles of the plus-energy house are south-facing orientation, ventilation with heat recovery, "ventilation" of the house, hot water and electricity generation using solar energy as well as sustainable e-mobility and car sharing. Can this concept make a contribution to climate protection and help reducing housing shortage and energy price crisis?

We talk about this with Rolf Disch, a solar architect from the very beginning. Disch graduated in civil engineering and architecture in 1969 and has been working with his own planning office for sustainable architecture with innovative energy concepts ever since.

Timeline:

  • 04:46 How does the sustainability concept of plus-energy houses work?
  • 07:36 What contribution can plus-energy hous developments make to achieving climate targets in the building sector?
  • 12:38 Keyword sector coupling: How do the heat, electricity and mobility sectors interact?
  • 17:26 What factors are currently hindering the increased use of plus-energy houses?
