Kö-Bogen, Düsseldorf, Germany

Integrated fire safety and security solutions

Customer

“A city of passion, a city of beauty:” This is how architect Daniel Libeskind describes Düsseldorf (Germany). Kö-Bogen, the shopping and office center that Libeskind designed on Königsallee, certainly contributes to the city’s beauty. The thousands of people who flock to the Kö-Bogen on a daily basis for shopping or for work owe their safety to a comprehensive security and fire safety concept that was developed for this architectural masterpiece by Siemens.


Requirements

The six-story Kö-Bogen building complex visually connects Königsallee, Düsseldorf’s elegant promenade, with Hofgarten Park and provides space for shops, offices and restaurants. It also includes a new waterway and a pedestrian zone – perfect for a summertime stroll. The traffic around the former Jan Wellem Square was moved underground to create this space. The two-part building ensemble, with its 42,000 m2 of floor space and undulating architecture, is the first milestone in a series of activities aimed at creating a modern urban center between the Schauspielhaus, Dreischeibenhaus, Hofgarten and Johanneskirche. Comprehensive Siemens safety systems were installed in the multi-lane traffic tunnel that runs beneath this building complex.

Solution

The thousands of people who flock to the Kö-Bogen on a daily basis for shopping or for work owe their safety to a fire safety concept that was developed for this architectural masterpiece by the owner and Building Technologies (BT) in cooperation with experts, insurers and the fire department. This concept defines structural measures and procedures in the event of an alarm. To implement the solution, BT installed approximately 2,500 fire detectors, which identify a possible fire right when it breaks out and signal the alarm to the fire department via a fire control panel. In the event of a fire, the building users are alerted by 700 alarm sounders. At the same time, the automatic escape door control opens suitable escape routes.
Should an evacuation be necessary, a Siemens voice alarm system guides people out of the building quickly and safely. "For a building like Kö-Bogen, where people come and go all day long, the alarming and evacuation chain must be especially well thought-out, and announcements and gathering points must be very clear," says Rüdiger Happ, BT Senior Sales Representative. "In an alarm situation, we must be able to guide people out of the danger zone quickly and safely, even if they don't know their way around."
The Siemens intrusion detection system and 200 acoustic glass break detectors protect the 16 shops and multiple office floors against break-ins. These systems detect all damage to the façade made of glass, white natural stone and landscaped diagonal cutouts in the façade. Video cameras guarantee additional safety while people work, shop and park their cars.

Benefit

Along with installing the equipment, BT also maintains the fire detection and safety systems and coordinates regular alarm tests and evacuation exercises in cooperation with the operator, a project development company called "die developer." BT also supervises additional expansions for new tenants who have their own fire safety and security standards and requirements.
