Building automation for HQ

by Mark Rowe

For its new corporate headquarters, the Continental logistics firm DB Schenker wanted building technology from a single source. The building owners chose the Desigo building automation system from Siemens for building automation – from the field level to room automation to the management level.

Siemens says that the dimensions alone made the job demanding. The system includes 560 Desigo room automation controllers, a DALI lighting control system, shading control for 2,000 blinds, an access control system with 40 Siport readers, a fire detection system with 1,500 detectors, plus a SINVR video surveillance system with the SiteIQ Analytics video management system. Some 30 cameras are interconnected, 24 of them around the building as a virtual fence solution. Any violation of the defined security distance triggers automatic recording. Because the building borders on public streets, the video system uses partial pixelation. Siemens also installed a CIC 2000 intrusion detection system according to German VdS standards. Some 50 elements were integrated, including motion sensors and door monitors.

All the systems and devices are interconnected via the Desigo CC building management platform. All disciplines can be centrally controlled and monitored from two operator screens. Support for open communication standards also allows the integration of third-party components. Even though DB Schenker uses an escape door control system from a specialised vendor, the doors can be unlocked via Desigo CC.

Desigo CC offers visualisation of the building disciplines. Operators can check the status of all the systems, devices and alarm management components – in each of the 431 rooms.

The setpoints for valve position, room temperature or lighting can be adjusted for single devices and rooms. On-screen graphics are used to control the various disciplines; Desigo CC displays floor plans identifying all the field devices installed in any room or floor. This also allows central control of cross-disciplinary scenarios such as an event in a specific room or a fire. Cross-disciplinary timer groups can be defined. Alarms are displayed for all disciplines on one overview screen. Reports and trends can be displayed automatically if so desired: PDFs are created and e-mailed based on individual preferences.

For maintenance, all the fire detectors in an area can be switched off from the control centre, eliminating the need to send technicians to each location. Visit www.siemens.com/buildingtechnologies.
