KUBIK in Bilbao

Project name: KUBIK

Location: Bilbao/Spain

Owner: project partner Tecnalia

General information of the building

KUBIK is a full-scale R&D test facility at the headquarter of project partner Tecnalia in Bilbao, Spain. KUBIK has the experimental capabilities to reproduce the conditions of use as realistically as possible, allowing validation of products and systems in conditions close to those of service (realistic scenarios). 

Additionally KUBIK offers a flexible infrastructure able to build realistic scenarios with different building components and systems, with the ability to assemble and disassemble them. This permits not only in service performance assessment, but also helps to develop and to evaluate assembly and erection procedures.
