Step by step to energy-efficient lighting control

Hochbahnhaus – Hamburg (DE)

With over 4500 workers, Hamburger Hochbahn AG is one of the biggest local transport operators in Germany. Since 1918, the company HQ has been located in the Old Town of Hamburg, in a former office building, the Hochbahnhaus. To modernise the building, an update to current building automation standards was desired.

There is activity in the building around the clock, as even at night, local transport does not stand still. Previously, the lights were switched on 24 hours a day. To combat this extremely high energy consumption, 128 occupancy detectors, type PD4-M-DIM, were installed in the corridors. In the underground rooms, occupancy detectors of type PD2 and PD4 were fitted, to optimise lighting control here as well. Lighting in the toilets is switched with the PD3N-1C-Micro. Thanks to the built-in microphone, if the light should switch off, this motion detector can be activated by a sound. The many individual lighting control zones in the Hochbahnhaus are coordinated with each other and enable optimum energy use. The new implementation has enabled a reduction in the number of hours the lights were on from 24 hours a day to 4-6 hours.
