City of Bremen

The City of Bremen standardizes on Wonderware software for centralized control of its many municipal properties. Benefits include decreased energy consumption and improved communications and reporting.

  • Rüdiger Heinenbruch, Technical Operations Manager

    As our regional supervisors can now access all heating systems from a central location, they will be able to successively optimize the systems one by one.

  • Goals

    • Unify more than 1,200 municipal properties under a single, open building management system (BMS)
    • Optimize the efficiency of heating systems in the buildings to cut energy consumption
  • Challenges

    • The buildings were running proprietary BMS from several different vendors
    • The properties were managed at six control facilities located around the city under the direction of five geographical districts and regional supervisors
  • Results

    • An open BMS based on the Wonderware solution is in place, centralizing the management of the extensive property list (160 facilities in all)
    • Regional supervisors all now have access to the BMS
    • Energy consumption is down by 15% to 18%
    • Assumed cost saving of more than € 30,000 (US$ 43,000) per year
    • Adding buildings to the system is simple and more efficient due to the extensibility of the Wonderware software
