The doubly-curved roof and latticed structural membranes knit by integrating advanced systems and human inputs, shape the next evolutionary step to sustainable construction. HiLo presents the attractive architecture woven by the combination of energy-resource saving construction and execution. Hilo designed atop Empa’s and Eawag’s NEST research and innovation building implemented by ETH Zurich’s Block Research Group and the Architecture and Building Systems Group in collaboration with many industrial partners take the giant leap of sustainable creations.
