City of Bremen Cuts Energy Consumption and Consolidates Building Management with Wonderware Solution
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.
Developing a Centralized Concept
With more than 1,200 municipal facilities covering over 1.8 million square meters (nearly 20 million quare feet) of floor space, the undertaking was not a small one. At the time, six control stations across the city were running a variety of proprietary building control systems. Reporting and sharing information in a consistent format was a challenge for the five egional supervisors. And employees had to learn to operate each of the different systems. Plus, adding new buildings was complicated and costly.
“Immobilien Bremen, Anstalt des öffentlichen Rechts,” the city’s property service company, evaluated a number of software possibilities as well as a formal engineering study that analyzed the City of Bremen’s current technologies and its roadmap for the future. Immobilien Bremen determined that the Wonderware solution would meet the city’s requirements for an open, vendor-agnostic BMS that would consolidate the various existing systems under a single operator interface.
