The striking red and black colours make the new trade fair halls in Dornbirn a place that is highly recognisable. Bartenbach lighting design advised the architects about both the colours and structure as well as the reflectance of the surfaces, so that the optimum space-light atmosphere could be achieved in the monochromatic spaces. The artificial lighting concept includes Tunable White in the halls and foyers. This allows the colour of the light used to be set anywhere between 2200 and 4200 Kelvin and thus adapted to the respective event.
