Brief

Researchers at ETH Zurich have finished work on a double-curved, self-sustaining concrete roof for a modular research and innovation building in Switzerland. A net of steel cables supports a polymer textile that together function as the formwork for the concrete.

 

Insight

After successfully building a prototype in 2017, researchers from the block research group (BRG) at ETH zurich have now completed a complex, doubly curved concrete roof in switzerland.

The roof has been designed for NEST (next evolution in sustainable building technologies), a modular research and innovation building that seeks to accelerate innovation in the construction sector. conceived by gramazio kohler architects, NEST provides space for testing new building technologies in practice.

NEST is owned by research institutes empa and eawag and is located on empa’s campus in dübendorf, 30 minutes outside of zurich. designed for the building’s HiLo unit, the roof has been completed by researchers from the block research group at ETH zurich in collaboration with partners from the construction industry.

The expressive shell structure demonstrates how high (Hi) performance can be achieved with low (Lo) embodied emissions by combining efficient concrete structures with novel fabrication and construction methods.
