HiLo is an innovative unit located in the NEST Platform in Dübendorf, Switzerland. Developed as a showcase for sustainable building technologies, it’s designed as a two-story collaborative workspace with both closed and open office areas.
The structure leverages unique building methods. For its roof, a reusable flexible formwork was utilized, consisting of a tensioned cable-net covered by a fabric membrane where concrete is sprayed. The floors, on the other hand, adopt a funicular shell design with vertical stiffeners to effectively distribute loads.
HiLo extensively employs concrete layers and steel reinforcements. The construction aims for minimized waste and recyclability. The building incorporates concrete of only 5 and 3 cm thickness, saving significant material without compromising strength.
This project stands as an emblem of sustainable construction. It conserves concrete, reduces steel use by up to 90% compared to traditional slabs, and prioritizes recyclability. Additionally, advanced building systems and an Adaptive Solar Facade ensure energy-efficient operation and user comfort, positioning HiLo as a pioneering step towards a more sustainable architectural future.
