Rolf Disch's Heliotrop House
Rolf Disch's Heliotrop House : TreeHugger
Our head is spinning from all the rotating buildings. Architect Rolf Disch built his own home as a test bed for solar systems. The house tracks the sun, so that its triple-glazed front can face the warming sun in winter and show its well insulated back in summer. The balcony rail is a solar vacuum tube to heat water. Photovoltaics on the roof rotate independently to track the sun, generating four to six times the energy needed for the house, making it beyond zero energy and into "das Plusenergiehaus" or a "Plus-energy House." If that is not enough, there is on-site composting, chemical free sewage treatment and rainwater catchment.
