As part of a Winter Experience Campaign, we have designed an educational window that gives recommendations on how to avoid mold and maintain a comfortable climate indoors. A supplementary 3D animation and key visual does not only attract the attention of passers-by but also encourage them to visit the store for a free energy-saving check and consultation. Besides, we have planned and implemented a community activity in collaboration with MitVergnügen Berlin, sharing energy-saving tip from the local community via another 3D animation in the respective stores.
