City of Bremen

Energy consumption is down by 15% to 18% and assumed cost saving of more than € 30,000 (US$ 43,000) per year

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

Solution

AVEVA™ Unified Operations Center

Result

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
