City of Bremen, Germany, Cuts Energy Consumption and Consolidates Building Management

When the City of Bremen needed to modernize the heating systems in several of its buildings, it analyzed the project and realized an opportunity. 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 – more than 1,200 municipal facilities covering over 1.8 million square meters (nearly 20 million square feet) of floor space. At the time, six control stations across the city were running a variety of proprietary building control systems, making reporting and sharing of information in a consistent format a challenge, and adding new buildings complicated and costly.
