This paper reports about the development and implementation of a free forming facade system, consisting of biobased sandwich elements. The build-up of the sandwich contains face sheets from natural fibre reinforced polymer (NFRP), using biobased epoxy resin and flax fibres, and a stuck cardboard core structure. Furthermore a formwork system was designed enabling biobased sandwich elements to be produced with special needs according to efficiency and architectural design. As a result, the biobased and sustainable sandwich elements exhibit low system weight, high sound reduction and sufficient load capacity for the use of facade elements. Additionally LED-stripes were integrated for illuminating the facade elements. Because of the regular pattern of the stuck cardboard core and the translucent face sheet laminates the facade works like a screen on which each created pixel can be controlled in rgb-colours. Therefore an area of 10 m x 5 m biobased sandwich facade with 25 elements is planned as a reference object in Chemnitz, forming a facade with 100 x 48 pixels. In summary the illuminated biobased sandwich elements produced with an efficient technology of production and with the use of renewable resources can replace extensively 3D-formed customary facade systems.
