Task: Overall conceptual design and realisation of RheinEnergie AG’s appearance at the E-world exhibition. Architecture and media. Solution: Energy turnaround on a beer mat: RheinEnergie AG is going Colognian – at the E-world in Essen, too. Visitors receive information about specific projects that have been realised relating to the energy turnaround on an interactive Rhineland map with the help of tagged beer mats, among other communication solutions. The space on these for one or two “Kölsch” beers is part of the concept, as are the Cologne-style giveaways and the communication media developed with sustainable deployment in mind.
