Siemens technology halves the energy consumption of the Staatsbibliothek zu Berlin
Siemens has technically modernized the Staatsbibliothek zu Berlin (Berlin State Library) to slash the facility’s energy consumption, lower its CO₂ emissions and better protect valuable cultural assets.
The Staatsbibliothek zu Berlin project is
part of the company’s ongoing collaboration with Berlin’s cultural buildings
that began in 2014. The library’s Potsdamer Strasse building is a protected
historic complex with around 106,000 square meters
of gross 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 percent 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 percent less electricity than the building’s old conventional lighting.
Over the
years, Siemens has modernized seven major 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.
