Researchers from the ETH Zürich have designed and built a prototype for a sinuous and micro-thin concrete roof using leading-edge fabrication methods.
The innovative formwork method has been tested and will be used for the first time in an actual construction project next year.
A research team headed by Arno Schlüter, Professor of Architecture and Building Systems and Philippe Block, Professor of Architecture and Structures, want to test the new and unique lightweight construction and combine it with adaptive and intelligent building systems.
The shell roof, which is doubly curved and self-supporting, consists of multiple layers. The inner concrete layer is covered by the insulation and heating and cooling coils. The second, exterior layer envelops the roof in this concrete sandwich design. Microfine photovoltaic cells are installed on the roof itself.
Thanks to the technology and adaptive solar power exterior, the unit is eventually expected to produce more energy than it actually consumes, making it a sustainable residential option.
