Did you know the Schau auf Graz app?

This week I researched ways to report faults in public lighting in Graz. First I used Google’s AI overview and then checked the information on various websites. The AI overview already gives a complete answer to the question: you can either contact Energie Graz, which manages the public lights in the city, or use the app Schau auf Graz (“look after Graz”).

Schau auf Graz is an Internet service that allows citizens to report problems and suggest improvements about public property, and there is also a section about lighting.

have been living in Graz for almost 3 months, but I had never heard of it and I wanted to know if I am the only one. I asked my colleagues from the Communication, Media, Sound and Interaction Design course how familiar they were with it. Out of the almost 30 people who answered, only 4 people from Graz/Styria knew it, the rest had never heard of it, including 2 people from Graz and surroundings. None of the people who are new in Graz knew the app. I reckon that it is a great way to improve public areas and think that it is a pity that it is not very common. I have never seen an ad about it, but I found it quite well hidden on the Stadt Graz website, under “apps of the city of Graz”.

I downloaded the app to see how it works and pretended I wanted to report a defect light in public space. I found the service to be quite easy to use and efficient, but some improvements could be introduced.

First of all, it is not easily accessible for foreigners living in Graz, because it is only available in German

The navigation bar at the bottom creates 5 different sections, from left to right: my concerns, all concerns, new concern (the biggest and most important button), information and profile.

When creating a new concern, you can choose from various categories, one of which is “Beleuchtung” (lighting). I tapped on it and was then asked to choose what kind of lighting I wanted to report. I was confused about the difference between the two options, but a quick google search and a closer look at the icons made me realise that the option on the left regards lights that illuminate façades and the other one concerns lampposts, which illuminate the streets. After selecting one, I was asked to choose what I wanted to report, and “fault” was the only option to choose from. A status bar and some sort of breadcrumbs menu allows you to track the progress and go back if needed. The second step is choosing the location of the fault, then you are asked to submit a picture. After that the report is ready to be sent.

You can then check the progress of your query on the “my concerns” page. I also took a look at other queries and found it convenient that you can choose if you want to see their status, their position on the map or a list.

How environmentally friendly is street lighting in Graz?

Last week I researched dark sky places, this week I have taken a look at how light pollution is tackled in urban areas, specifically in Graz.

First of all, I researched national laws. The Tyrol Competence Center on Light Pollution and Dark Skies lists Austrian regulations on light pollution. As opposed to other EU countries, Austria has no explicit legal requirement to operate street lighting, but these can be derived from various standards and legal norms, such as:

  • ÖNORM EN 13201, Part 2-5 Road Lighting (2004), which lists standards used for planning public lighting systems in all EU countries;
  • ÖNORM O 1055 Road lighting – Selection of lighting classes – Rules for the implementation of CEN/TR 13201-1 (2017), which includes provisions for dimming during off-peak periods;
  • ÖNORM O 1051 Road lighting – Lighting of Conflict Areas (2007), which contains recommendations for lighs illuminating zebra crossings, roundabouts, car parks, etc.;
  • RVS (Guidelines and Regulations for Highways) 05.06.11 and 05.06.12, which includes limit values and criteria to avoid undesired effects of artificial lighting on drivers.

According to Energie Graz, which operates the public lighting system of the city, a total of 28,802 lights illuminated the city as of 2021. Due to the population increase and in order to improve the feeling of safety, in previous years the light system has been expanded by 21%, which corresponds to 98 lights per 1,000 inhabitants. One might think that this would have led to an increase in energy consumption, but actually it fell by over 11% between 2004 and 2021, thanks to the conversion to modern LED street lighting. This has been the case of around 31% or almost 9,000 light points on streets, squares, parks, footpaths and cycle paths of Graz. Apart from having a significantly lower energy consumption, modern LED lights have lower maintenance costs, a long service life, reduced CO₂ emissions, and less light spill, contributing to less light pollution. 

LED street lighting also adapts to the needs of citizens in a smart way. For example, when footpaths and cycle paths are not used at night, the lights are dimmed to 10% of their usual brightness.

During the public meeting of the municipal council on 15 February 2024, it was mentioned that Ankünder GmbH, the leading provider of outdoor advertising media in Styria, had been switching off all illuminated advertising signs from midnight to 5 a.m., except at bus stops for a year.

During the course of the meeting, KPÖ municipal councillor Max Zirngast asked the city to collaborate with the Chamber of Commerce (WKO) to develop a concept to limit light pollution. It motivates Graz-based companies to minimise their light emissions from illuminated advertising and illuminated displays. Most parties voted in favour, but I have not been able to find follow-up information about the proposal’s realisation.

Energie Graz, being responsible for the public lighting in Graz, can be contacted to report faults and problems with street lights. This can be done via e-mail, call or by downloading the “Schau auf Graz” app.

In the next article, I would like to research more about this app and other ways to raise your voice about light pollution in Graz.
