Climatic wind tunnel with altitude simulation
Challenge
With the construction of the new Simulation Center, Škoda Auto is pursuing its goal of creating state-of-the-art conditions for the development of sustainable vehicle technologies.
The facility should be capable of realistically simulating a wide variety of climatic conditions and driving situations—from extreme heat with intense sunlight to freezing temperatures, variable humidity, and rain.
The particular challenge was to combine these requirements in a semi-wind tunnel with altitude simulation up to 5500 m above sea level.
This is a unique project within the global Volkswagen Group.
In this demanding project, ETS assumed overall technical responsibility for the building services and technology.
The implementation required precise planning, in-depth technical expertise, and close coordination with the client and plant designer..
