In the Nijenoord building of MVGM the residents had a lot of complaints of guests and delivery staff feeling lost in the building. This caused a lot problems with deliveries and residents picking up guests in the lobby (or on other floors). The uncommon floor selector seemed to be the problem.
The floor selector works a little different than the usual selectors. In this case you have to select the floor before you go into the elevator instead of doing this when you are inside the elevator. The manual that was placed after everyone requested this was long and complicated.
After interviewing a lot of the residents, guests and delivery staff it became obvious that a clear, short message was needed. The bright, blue colour was chosen because it attracts the eye and the colour is associated with information.
Since the new sign there were less residents needed to go to the lobby because people were no longer lost in the building and more packages were delivered at the front door.
