The HfG Karlsruhe is housed in a former munition factory and is therefore protected as a historic building. The new orientation system consists of three components; door signs, directional signs, and orientation signs. Anodized aluminum door signs wrap around door frames without any mounting hardware. These signs have room numbers silk-screened directly on the metal. Directional signs feature large numerals that are easy to read from a distance, even in dim light. A modular system of orientation signage is mounted without screws on technical rooms at all exits. Information is permanent with the exception of a personnel register, which is refreshed every semester. Giant numerals and larger signs with more details indicate the current floor.
