Aurubis - Nordic Brown Light
The external skin of the new library is dominated by copper. The darkening pre-oxidised copper sets the new library apart from the whiteness of the surrounding buildings. Copper is not a new material to the area but in the Aalto Centre it is mainly the roofs that feature the material’s beautifully patinated green surfaces. In the new library, copper has been used comprehensively across facades, plinth and roofs – creating a single-material skin.
A special shape of copper shingle was specifically designed for the facades to give the building a highly individual, lively and vivid surface. In some situations, the shingle surface is formed into ventilation slots to accommodate air handling. Copper is also used to form vertical grilles and as a door facing to maintain the material continuity.
