Gebouwenautomatisering voor onderwijsinstellingen

The Mannheim University and also the University Library were founded in 1967 and are resident in the Mannheim Palace, one of the oldest monuments in Mannheim. The lack of accessibility for handicapped people and technical deficits as well as functional deficits led to a fundamental restoration of the business administration library in the south wing of the Mannheim Palace. During the restoration phase the new systems were equipped with DEOS building automation.

For the air-conditioning a ventilation system without static heat areas was installed in all rooms. The energy-saving and highly efficient COBAOPT system (today: OPENdynamics) controls a total of 650 physical data points of the system. For the individual air-conditioning of each room 25 separately controllable zone heating elements were created. Due to a remarkable decrease of flow noises and a strong rejection of air turbulences the comfort could be increased considerably. In each room the room temperature, -humidity and –quality (CO2) is observed by sensors with the assistance of a differential pressure transducer. All physical and virtual technical control data are recorded in arbitrary time intervals with the DEOS BMS-software OPENweb. The software also observes the central fault- and alarm management system.

The company Fiehn building automation and their partners were awarded with the „Trust Innovation Award” 2011 of the savings bank Schwarzwald-Baar. The reason for the award was the newly built school “Katharina-von-Gersdorf” as passive house. The project was supported with financial aid by the German Environment Foundation.

The digital automation system for the control and regulation of the heating-, ventilation- and air conditioning systems of the passive house project was made by DEOS AG.
A OPEN 700 EMS automation station was chosen as hardware. All physical and virtual control-technical data are recorded in user-defined time periods with the help of the building control system software OPENweb.

The university was founded outside the city as a campus university in Bochum´s district Querenburg: Apart from a few branches, all faculties are situated at the campus.

In 2010, the newly constructed buildings ID and IDN were equipped with controllers from DEOS AG. The new energy management stations control all ventilation systems as well as the heat generation and cooling of the building. Furthermore, a single room control was realized to meet the different room requirements (e. g. for laboratories, measuring chambers, offices, auditoriums and canteen). In the different information points of the buildings ID and IDN in total 15 OPEN 4000 EMS (energy management station) and 6 OPEN 800 EMS were installed. Here around 12,000 physical in- and outputs are recorded.

Throughout the whole project 54,000 BACnet data points were created, from which currently 16,000 data points are connected via BACnet/OPC conversion to the existing campus building management system. The installed building management system allows an easy operation.
