| has gloss | eng: The Heliotrope is an environmentally friendly house designed by the German architect Rolf Disch who also designed the Sonnenschiff (Sun Ship). Three such houses exist in Germany, the first experimental version having been built in 1994 as the architects home in Freiburg im Breisgau, while the other two are used as exhibition buildings for the Hansgrohe company in Offenburg and a dentists lab in Hilpoltstein in Bavaria. The most important characteristic of this house is its low consumption due to its ability to rotate according to the sun's position as well as its solar energy production thanks to roof-mounted photovoltaic panels. |
