Every building should eventually generate its own power! Preserving important cultural assets and combining them with technology and good architecture is a true artform. The 350-year-old group of protected historic buildings has been carefully restored. All improvements are clearly visible and limited to exposed concrete and larch wood – both untreated – as well as black steel and glass. A photovoltaic system and solar panels collect solar energy. Surplus energy collected in summer is stored in the rock via the geothermal probe and can then be used as a climate-neutral energy source in winter.
