"1 : 1 Signage, Orientation, Identity" is a special book. It not only describes the projects of the last ten years and the way of working of the communications design company Moniteurs, but the projects are also graphically brought into focus: in this way the book shows Moniteurs orientation systems on a 1 : 1 scale. The concepts of individual projects are presented in short, concise texts with many photographs and infographics, while an interview with the three owners of the company, Heike Nehl, Sibylle Schlaich and Isolde Frey, gives an insight into their approach. Moniteurs has existed since 1994. In addition to the design of signage and orientation systems, the focal points of the company include information design and corporate design. This range is reflected in the diversity, depth and precision of the projects. Many of them have received awards, including the red dot award for the communication design of the orientation system for the Aufbau Haus , and the Iconic Design Award 2013 for the Potsdamer Platz orientation system. The BMW Plant Orientation System project was included in the touring exhibition of the Goethe Institute s The Dimension of Surface Communications Design in Germany. The signage system project developed for Berlin Brandenburg Airport by the communications design ?rm Moniteurs is presented in this e-book. The four chapters explain how the signage system shapes the structural identity of the airport: The "Identity" chapter deals with the architecture, the colors, the development of the fonts and the pictograms used; "Function" explains how typography is employed, what labelling types and dimensions are used, and how guidance and orientation works for visitors to the airport. The "Development" chapter explains how the notices and labelling are tested to ensure they are legible, e.g. at various testing points, and are then produced in line with the ?ndings. "Beyond the Terminal" deals with how the signage system applies not only in the terminals, but extends outward to other buildings, building sections and adjacent sites, for the motorway accesses and exits and also for links to Internet and information monitors. In addition there is a brief review examining the art-in-the building projects. The digital form of the book has opened up the possibility for presenting extensive material, interactive graphics and ?lms explaining everything in detail.
