BERLIN, Germany, Aug 5, 2025 – Siemens has upgraded Staatsbibliothek zu Berlin (Berlin State Library) with intelligent building technology that reduces energy use by 52% and prevents 3,745 tons of CO₂ emissions each year. The system stabilizes climate conditions to protect over 32 million media items. The €20 million project is paid with energy savings contracting, using a model that helps public and private facilities modernize without upfront costs.
The Staatsbibliothek zu Berlin project is part of the Siemens’ ongoing collaboration with Berlin’s cultural buildings that began in 2014. The library’s Potsdamer Strasse building is a historic complex with around 106,000 square meters of floor area. Carried out as part of the federal government’s decarbonization program, the Siemens project contributes to the program’s 2030 target of reducing CO₂ emissions from state buildings by 65% compared to their 1990 levels.
New technologies installed by Siemens include the Desigo building automation system, room operator units, sensors and a cloud-based energy and asset management platform. Ventilation is optimized through flexible systems for heating, ventilation and air conditioning. In addition, 5,300 LED lights consume up to 80% less electricity than the building’s conventional lighting.
Over the years, Siemens has modernized seven cultural sites in Berlin, such as the Neue Nationalgalerie. Between 2014 and 2024, around €25 million in energy costs were saved and 3,745 tons of CO₂ emissions were avoided annually.
