The idea behind

A 92 per cent reduction in energy costs in this project.

The energy efficiency of LED sensor lighting can be significantly improved through ‘smart lighting’. The parking deck of the underground car park was fitted with 240 wirelessly networkable RS PRO Connect 5100 LEDs from STEINEL, each with a power rating of 33 watts, with every second luminaire being a slave version. The luminaires were divided into four lighting groups and controlled intelligently. The creation of lighting groups, the switch to a 10 per cent basic lighting mode after one minute of inactivity, and the lights switching off completely after 15 minutes have resulted in a measurable energy saving of 92 per cent compared with the old lighting system.

The lighting guides users as they make their way through the underground car park. The lights are only switched on where they are actually needed. This ensures that energy is only used for lighting when it is actually required.

The project

Client: City of Zurich
Location: Heuried residential area, Zurich/CH
Construction status: in operation since 2019
Pilot project on a parking level
Installed: 240 x RS PRO Connect 5100 LED
Services: software, hardware and services

Overview

The lighting has been improved, which increases safety in the vehicle and pedestrian areas.

Variable holders on the underside make it possible to use existing holes.

Easy and convenient adjustment and operation via app, basic and main light levels, as well as grouping and range.

92% lower energy costs. Even we were amazed.

The energy efficiency of LED sensor lighting can be significantly increased by "light intelligence". The car park deck of the underground garage was equipped with 240 wirelessly networkable RS PRO Connect 5100 LED lights from STEINEL with an output of 33 watts, with every second light being a slave version. The lights were divided into four lighting groups and intelligently controlled. Forming lighting groups, switching to a 10% background lighting mode after 1 minute in the event of absence and switching off completely after 15 minutes has led to a measurable energy saving of 92%.

The light accompanies the user on their way through the underground car park. The light is only switched on where it is actually needed. This ensures that no energy is wasted.

"We were sure that we would save a lot of energy by installing the latest generation of luminaires. We were impressed by the fact that networking and intelligently controlling the luminaires increases energy savings many times over."

Project details

RS PRO 5100 C

On the car park level, every second luminaire is one without a motion sensor, i.e. an RS PRO 5100 C. When connected to the master luminaire, both react as one complete luminaire. This helps to reduce investment costs.

About the product

RS PRO 5100 SC

Connected via Bluetooth, the RS PRO 5100 SC LED sensor batten luminaire is easily and conveniently adjusted and operated using an app.

Full operation under 10 per cent

Installation of the RS PRO Connect 5100 LED has significantly improved lighting on the car park level. This makes the user experience much more pleasant. At the same time, measurements in practice have shown that electricity consumption has been reduced to 1.1 kWh/m², which is well below the current limit of 2.2 kWh/m². The measurements also showed that the lighting is only at full power 9% of the time and at a dimmed level 45.4% of the time. The lighting is in standby mode 45.6% of the time.

94^MWh

Based on the project calculations, this represents a potential saving of around 94.3 MWh per year.

220^lux

With the new lighting solution, the lighting level has almost doubled on average from 120 to 220 lux.

92^%

The networked, smart lighting solution has enabled significant energy savings to be achieved.

Easy networking and operation via app

To light an area as extensive as the parking level of an underground car park, it makes sense to form groups of lights. With the RS PRO Connect 5100 LED, no additional cables need to be laid for this purpose. The lights are simply connected to each other via Bluetooth using the intuitive STEINEL app. For each of these light groups, it is necessary to define a group master in the app. All the lights in a group then work the way the group master is configured. Other light functions, such as the neighbourhood function, as well as light parameters such as twilight setting, basic light level, main light and time settings can also be easily selected via the app. Practical: All light functions and settings are conveniently selected from the ground using the app. No ladder is required.

Parking & Transportation

Parque Europa car park – Leiria, Portugal

Lead-time lighting and STEINEL’s swarm intelligence ensure that lighting in Parque Europa in Leiria, Portugal, is switched on and off as required. The three-storey car park has been fitted with the RS PRO 5100 SC, the RS PRO R10 SC and products from the XLED PRO ONE series, which provide stairwells and parking areas with lighting tailored to their needs.

stairs

The networking of the RS PRO Connect 5100 LED via Bluetooth makes it possible, for example, to combine car park lighting with R series luminaires in the stairwell.

functional space

On the way to and from the car park, the lighting in the entrance can be linked to the car park lighting. Smart, connected lighting systems can help to enhance the perceived quality of the environment and improve wayfinding.
