Connected Lighting solution

92% energy savings in the car park of the Westmorland Shopping Centre

The idea behind

Westmorland Shopping Centre car park

Multi-storey and underground car parks are often in operation for long periods, which is why effective lighting is essential – not only for safety and comfort, but also in terms of energy efficiency.

In Kendal’s 7-storey car park, the original installation comprised 544 luminaires across six outdated lighting types. For intelligent lighting control, the RS PRO 5100 SC was chosen as part of STEINEL’s Connected Lighting solution. Bluetooth Mesh technology enables wireless configuration and commissioning via the STEINEL app. Features such as the neighbouring group function and the basic lighting option ensure an immediate reduction in energy consumption compared with the old installation, and thus also a reduction in costs. This is not merely a technical upgrade, but a strategic leap towards a smart infrastructure.

Lighting solutions for modern requirements

The 754 RS PRO 5100 SC luminaires are synonymous with reliable, needs-based lighting technology. With a high luminous efficacy of 137 lm/watt, they offer maximum safety. Lighting is provided only when required and precisely where it is actually needed – for optimum illumination without lights being left on unnecessarily.

Thanks to the fully adjustable light level, the luminaires can be flexibly adapted to any application scenario.

About the RS PRO 5100 SC

The 754 lights were installed both on the car park decks and in the stairwells. The Bluetooth Mesh network enables the lights to communicate with one another and form groups of lights. When a person moves from the car park deck to the stairwells, the last group of lights on the car park deck switches on the first group of lights in the stairwell. This prevents dark corners and nooks, whilst maximising user comfort. At the same time, lights that are not needed remain switched off or set to low-level lighting, thereby drastically reducing energy consumption.

The fact that they only require a single supply to power the light, sensor and emergency function, with connections to other lights being via Bluetooth, ensured a minimal amount of wiring and containment was required, speeding up the installation.

Light intelligence instead of permanent lighting

The Connected Lighting System offers exceptional flexibility.

The STEINEL Connect app is the heart of Connected Lighting. It allows you to intuitively commission, configure and network lights, as well as parameterise entire lighting groups and complete projects.

All settings can be easily adapted to the environment and current customer requirements – including the neighbour function (swarm function), twilight threshold, basic and main light intensity, and time parameters.

The result is a fully customisable, intelligent lighting system that is easy to set up and optimise in terms of performance, safety and comfort.

The grouping of luminaires is crucial for efficient lighting of large areas such as multi-storey and underground car parks. The luminaires in this car park were grouped in threes. Each group was connected to an adjacent group of three luminaires. When the immediate luminaire group detects movement, these luminaires switch on at 100% brightness, while the connected neighbouring groups switch on at 10% brightness. Each group follows the specifications of a designated master luminaire, which is configured directly via the STEINEL app.

When the sensor lights detect movement, the lights in the group switch to 100% illumination. If no further movement is detected, the lights remain at 100% for the defined period of one minute.

If no new movement is detected during the delay period, the lights switch to 10% base lighting. This saves energy compared with 100% lighting whilst at the same time ensuring that users are not left standing in the dark unintentionally.

If no movement is detected during the follow-up time in the basic light, the lights switch off. Only when movement is detected again do the lights switch back to 100%.

Maximum flexibility

In this car park, the two lowest floors are reserved as additional parking spaces for exclusive use during peak times. The car park operators wanted to be able to deactivate the sensors on these levels to prevent their use – without interrupting the emergency lighting, which would otherwise take time to recharge.

This is easily possible with the STEINEL Connect app. Users can selectively deactivate sensors in selected lighting groups at specific times, while the emergency lighting continues to operate without interruption.
