BREMEN, Germany – When the City of Bremen needed to modernize the heating systems in several of its buildings, it analyzed the project and realized an opportunity to do more. Besides improving energy efficiency, there was the potential to implement a new building management system (BMS) that would bring greater control and provide far-reaching positive effects across the city’s extensive portfolio of properties.
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 a 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 AVEVA 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 AVEVA software
“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.”
