The research and innovation building NEST of Empa and Eawag can now be visited virtually at any time and from anywhere in the world. The launch of the virtual NEST tour is a further step towards closing the gap between laboratory research and market entry. By making numerous innovations, developed and demonstrated at NEST, accessible to a much broader and more international audience, the virtual NEST is making a significant contribution to ensuring that sustainable innovations in the building and energy sector can spread faster and thus gain a foothold in the construction industry.
