Building description of the I&C system for the KA high-rise building
The high-rise building of the German Pension Insurance Baden-Württemberg, which was put into operation at the end of 1963, was completely renovated between 2003 and 2008. The high-rise building consists of 20 office floors and another technical floor on the roof as well as two basement floors. Basically, the floors are divided into offices for 1-4 people. The special feature of the I&C technology is that it has been executed axially white on the floors, so that the greatest modularity is guaranteed and the office sizes can be adapted according to the circumstances.
Existing I&C technology:
The German Pension Insurance Baden-Württemberg is planning to migrate the entire automation stations of the high-rise building (from the ground floor to the 21st floor). The switchgear is all ≈ from 2005 to 2009. The automation focus and associated room automation is thus approx. 17 years old and has exceeded its useful life in accordance with VDI 2067.
The technical centers with the automation focal points are located in the basement, in the 1st basement, on the 1st / 2nd / 4th / 7th / 10th / 13th / 16th / 19th floor, on the 1st and 2nd attic floors.

On the black boxes, the data points are connected via LON gateways and include the window drive, the glare protection, the radiator thermal drive, the cooling valve and the light inside and outside. It is operated via a room operating unit (SRM). Depending on the usable area of the individual offices, the room units extend over several axes.
The 2nd floor has already been migrated. The remaining floors are included and taken into account in this scope of services.

Basement: 2.87 m
Ground floor: 3.41 m
1.Obergeschoß 3,20 m
2.Obergeschoß 2,84 m
The gross floor area (GFA) of the high-rise building is approx. 23960 m².
Corridors and corridors are escape routes and may not be used as storage or intermediate storage.
In the high-rise building, the entire I&C technology is to be renovated. The other parts of the building, the doctor's building and the canteen building, will remain in the existing building. The removed spare parts are to be reused for the other parts of the building.
