Eco Factor: Solar-powered house generates six times more energy that it needs.
The Heliotrope House by German architect Rolf Disch is a cylindrical house that tracks the path of the sun to give maximum access to daylight and allows the onboard solar panels to generate more energy. The record-breaking design is one of the first residential buildings to generate more energy than it uses.
The rotating mechanism allows the house to generate up to six times more energy than the requirement. The house rotates slowly around a central axis to catch maximum sunlight for the solar panels. The house features a rooftop deck laden with solar panels, which are supported by railings. These railings double as passive water heating pipes to serve the house below.
