As part of this reference project, a reduction in operating costs of 94.4 per cent was calculated.

Underground car park, Cologne

The end of expensive continuous lighting

Outdated lighting systems and lights that are left on round the clock – such blatant waste of energy is by no means an isolated case. With a

modern intelligent lighting solution from STEINEL and a smart control system, energy and running costs can be reduced depending on usage, operating hours and building conditions, as demonstrated here in an underground car park in Cologne. To ensure that planning is not based solely on gut feeling, measuring lighting and usage conditions in advance using the PROLog measuring device provides reliable project information on potential savings.

About the product

Location: Cologne, Germany
Building status: completed in 1982, renovated in 2020
139 car parking spaces in 4 parking sections
Product installed: RS PRO Connect 5100 LED
Planning aid: PROLog from STEINEL
Result: 94.4% reduction in total operating costs
Amortisation in under 2 years

Improved lighting conditions whilst reducing operating costs.

Compared with the old lighting system, illumination in all areas has been increased by 30 per cent. The improved lighting conditions make the underground car park a more pleasant place to use and improve visibility when manoeuvring in the traffic area.

Before: The old lighting provided only a small amount of illumination.

After: Installation of the RS PRO Connect 5100 LED significantly improves illumination.

"In addition to the easy installation, we were absolutely convinced by the outstanding technical possibilities for setting and adjusting the RS PRO Connect 5100 LED. This allows us to optimally adapt the lighting control to the respective situation on site and to exploit the energy-saving potential in the best possible way."

Low operating costs, brighter light

Sensor-LED lights in an underground car park with a parked car in the background

The outdated lighting in the underground car park has now been replaced by RS PRO Connect 5100 LED sensor-switched diffuser luminaires. A control system that is tailored to the local conditions ensures that light is only ever switched on where users are present and light is needed. Individually adjustable time intervals ensure that the light dims to a lower level when it detects that the area is no longer being used. The light switches off completely when no one is in the area for a longer period of time. This lighting solution can reduce total operating costs by 94.4%.

About the product

More comfort, lower costs.

Reliable analysis

STEINEL’s PROLog measuring device identifies specific potential savings in energy, lighting and
servicing costs based on user behaviour and the lighting conditions on site.

Easy assembly and installation

All the lights are conveniently started up and adjusted by the STEINEL Connect app. Practical: existing drill holes and cables can easily be reused.

Flexible networking

Using the app via Bluetooth Mesh, several RS PRO Connect 5100 LEDs can be networked, grouped and controlled in an energy-efficient manner. With this intelligent lighting solution from STEINEL, significant energy savings can be achieved, depending on usage and on-site conditions.

The light accompanies the user on their way

The neighbour function allows luminaires in adjacent areas to be activated. This means that the light is always switched on exactly where the user is currently located and will be shortly.
