Smart and efficient lighting in Stockholm

This press release is also available in Swedish, see the PDF-file below.

During late evenings and nights the need for fully-lit streets and other outdoor environments are often less. Turning off the lights can however make people feel insecure. Thanks to lighting controls and LED it’s possible to meet people’s needs and save energy at the same time.

- We are taking yet another step forward to make Stockholm modern and climate smart. The new technology has the potential to reduce the city’s energy consumption by 50 percent. In the long term we want to have this type of energy-efficient lighting throughout the whole city, says Daniel Helldén (MP), city council.

In the Stockholm area, there are 50,000 luminaires lighting up the parks and the walking and bicycle paths. With the new technology the energy consumption can be reduced by 4,000,000 kWh, which is equivalent to the CO₂-emission of 100 cars driving 20,000 km per year. Therefore the city is now evaluating different kinds of solutions for walking and bicycle paths within the new project “Advanced lighting control for outdoor lighting”.

In Djurgården, daylight and presence controlled LED luminaires with solar cells have been installed. On the other side of the city, in Bromma, LED luminaires with advanced presence control have replaced old conventional luminaires. The project will show the opportunities and differences between the two parts of the project.

- The new lighting on Djurgården is driven completely by solar cells and was a good choice for both the environment and the users. Another advantage is that we don’t have to dig too deep in the ground to make it work, says Gunnar Björkman, park manager at The Royal Djurgården Administration. 

The goal for the presence detected lighting in Bromma is to save at least 50 percent compared to the old solution, without compromising on perceived safety and visual comfort. The project is a further development of a project by the Kungsholms Strand in the city centre of Stockholm where presence detected lighting was installed with good results (see the link below).

The project is managed by Sustainable Innovation (Sust) and KTH Light Laboratory in collaboration with the Royal Djurgården Administration, Leading Light, City of Stockholm and Fagerhult and will continue until fall 2015.

Facts

Bromma between the Tunnlands road and the Gustav III road

Along the walkway between the Tunnlands road and the Gustav III road in Bromma the city of Stockholm has replaced the old post top luminaires with the modern LED luminaire Lunova from Fagerhult, equipped with a radio control system from Tritech. The system is advanced and the radio communication makes it possible to increase the light where the pedestrians are and thereby also increase the sense of security.

Djurgården by de Besches road

Along De Besches road, which previously lacked lighting, the Royal Djurgården Administration installed 42 Active Lights street lights and 32 bollards. The lighting is powered 100 percent by solar energy and is presence detected. The system has an advanced lighting control and radio communication between the posts, which means that the light level increases to create a sense of security for pedestrians.
