Project year: 2023 The publicly accessible parking garage “Hofdienergarage” in the city center of Stuttgart comprises approx. 558 parking spaces. The repair of levels 1 to 6, with approx. 13,500 m² of parking space, is being carried out using a KKS system with a carbon layer. Due to the very low clearance height of the flat ceilings, it was not possible to lay large cable harnesses under the ceiling. This is where the Noxeco KKS system with its decentralized Smartboxes comes into its own. Levels 1 and 3 have been in operation since March 2023. The remaining levels will be completed by 2025.
