Ozeaneum, Stralsund, Germany

BACnet solution for building automation


Opened in 2008, the Oceaneum in the Hanseatic city of Stralsund exhibits the underwater worlds of the Baltic Sea, North Sea, and Arctic Ocean. The Natural History Museum, a branch of the German Oceanographic Museum (Deutsches Meeresmuseum, DMM), has a floor space of 8700 square meters and is home to about 7000 fish and sea creatures in 39 tanks.

As many building and aquarium engineering systems as possible needed to be connected to a common control center in the new building so that employees would not have to deal with different control and regulatory systems and their own specific user interfaces and operating philosophies. Accordingly, the building automation and control system needed to meet high demands with regard to integration of third-party systems, migration capability, and flexibility, as well as operability over the intranet of the DMM.


Only the Desigo building automation and control system could meet all the requirements. For example, the hazard alarm system Sigmasys was able to be directly connected and visualized using the BACnet protocol. Other peripheral components and systems, in particular the aquarium technology, are connected using proprietary couplings, and the electrical systems are connected using EIB couplers.

A Desigo web server that serves any number of authorized PCs in the office network provides visualization of the technical plants. At ten information focal points, additional workstations visualize the systems in a manner proximate to the function. All aquarium technology and building systems are visualized uniformly using Desigo Insight.

For energy- and cost-efficient operation, all measured values from 39 PXC automation stations and more than 50 heat quantity meters can be stored in a separate Desigo management station (CAFM server) and analyzed with the energy management software ADP.


For the operator of the Ozeaneum, the uniform visualization of all systems of the building and aquarium engineering on the BACnet building management and control system Desigo, as well as the central data archiving and analysis, increase safety and security immensely. This allows the energy consumption as well as the energy and water costs to be kept under control over the long term, securing the economic operation of the museum.


  • 1 Desigo Insight BA system with 8000 data points, of which 4200 are physical

  • 1 CAFM system for industrial system controlling and for consumption and energy management (PDM-ADP)

  • 1 WEB / Terminal Server Desigo WEB as a link to the intranet of the Ozeaneum and DMM

  • 39 Desigo PXC automation stations distributed over 10 information focal points

  • 9 workstations for function-proximate visualization of the systems using energy-saving terminal server applications

  • Third-party systems coupled to them: hazard alarm system Sigmasys, access control, EIB/KNX system, Mod bus counter, aquarium engineering, LON Sicotronic kitchen optimization, and an existing Desigo system in the dmm connected using ethernet (fiber optic cables)
