Elements
The BDF has opened their third FertighausWelt in Wuppertal, where all vendors, who are represented by the association, are showing their houses. The long-term aim of the park is to work energetically independent. The idea was to break down the topic energy and chose the 4 elements, the basis of all energy extractions which are used in the park. The visitors are using the installation intentionally or can influence it by walking around in front of it.
