Smart Cities on the Rise

| 13. Okt 2020 | in Uncategorized | Keine Kommentare

Cities take their innovation into their own hands! 

Three hackathons in a row, tackling different aspects of urban life at different cities scales, show us how smart cities will be developed locally, by and for their inhabitants, with Open Data as raw material for their reflection and solutions.

The first hackathon, Smart City lab Lenzburg, will take place either in Lenzburg or online on the 14th and 15th of November 2020 and is strongly anchored in the local community: taking place centrally in the beautiful Aula of one of the schools, it will tackle many questions that are specific to Lenzburg: for example after a new 2000W neighbourhood was build, the following questions arose: How to optimize this new way of urban living? Which lessons can we learn? Which solutions could be adopted by the rest of the city? Another challenge will be how to reunite the different parts of Lenzburg, which were cut up by the train tracks and the highway at different moments of its development? Could optimizing public transport to the different neighborhoods be part of the solution? Or making initiatives and activities in different parts of the city more visible to the rest of Lenzburg? Questions also arise from the side of the city administration and services, and from the energy provider. Solutions might be digital or not, but while their starting point is local, the solutions might concern us all.

Shortly after, on the 27th and 28th of November the Shape my City – Open Data Hackdays, organized by the students of the master’s degree course in Applied Information and Data Science of the Lucerne University of Applied Science and Arts, will take place in the Laboratorium, a start-up incubator hosting the event for the second year in Lucerne. For this larger touristic and academic city, one of the focuses will be to understand the needs of the different types of inhabitants, users, visitors and stakeholders of the city. How can we shape the interaction for better communication and services? And how can we incentivise behavioural changes for a more harmonious and sustainable city life? The other topics revolve around exploring the potential of the urban fabric for energy production, climate change mitigation and here too, the model role of 2000W neighborhoods.

Then, on the 29th & 30th April 2021, the Energy and Climate Hacks will take place in the city of Bern, as a parallel event to the Decarbonizing Cities Conference. During this event, smart urban living will be addressed through the lens of energy efficiency not only in Bern but also in some british cities, throwing a bridge between common issues and needs across borders.

The beauty of this series of events is not only that it will allow us to go deeper in the development of solutions, but also that it exemplifies how bottom-up locally embedded initiatives actually tackle global issues and how those proposals, tested at a local scale, might help our society beyond their original purpose.

These events are open and free of charge, like all our other hackdays, so take part, you too have a take on how our future smart cities should be!

Energy Data Hackdays 2020, the results!

| 6. Okt 2020 | in Daten, Energie, Event, Forschung | Keine Kommentare

The excitement before the new edition of the Energy Hackdays in Brugg was a bit special this year. Besides the usual sweet little heart pinch of the leap into a new group, the discovery of the challenges and the satisfaction of seeing this particular event repeating for the second time in Brugg, there was happiness but also respect about having the Energy Hackdays taking place mostly on site at the Hightech Zentrum Aarau.

So we met in person and as far as we can say, it has been worth it! 13 really ambitious and technical challenges met 85 participants who were nonetheless ambitious and highly qualified! Two big themes emerged this year and predictions based on machine learning was one of them. Predicting performance, usage patterns, anomalies or even failure, in order to plan, use and maintain infrastructure more accurately. Reaching these goals of course allows a much better resource and production management. 

The other big topic covered by several challenges was the question of visualization and interfaces, especially for smart-meters: How to help users, scientists, producers or end-consumers to read flows of data and allow them to interpret and decide or react appropriately to a given data supported information? How can they analyse and control different aspects of their infrastructure or installation? Tangent to this topic were challenges that attempted to allow a market overview for the consumer, in this case the market of E-Car charging stations, or to visualize the overall live electricity consumption of Switzerland.

As far as I can judge and from what I heard from the challenge owners, the results blew us away! While the project descriptions might be a bit less accessible to the public than some from past hackdays, the approaches and results certainly correspond to a present need in the energy industry and comfort us in the conviction that hackathons and collaborative work with Open Data do support high-end innovation.
We were also very lucky to welcome the team of Campus 21 who harvested the visions of some of the participants for the future of Open Energy Data.

See you all next year!

The 13 projects developed during the hackdays

District Heating Optimisation  

Decrease gas peak boiler runtime due to better storage operation: heat demand forecast, improved storage control, better storage operation.

PV self-consumption optimization

Evaluate and optimize trade-offs in the design of battery storage for PV systems, so our customer can select, whether they want the most economical battery solution or maximise their autarky. Our tools calculate the maximized economic benefit over lifetime.

Read your own Smart Meter

Read your Smart Meter through the local Customer Information Interface (CII) and visualize your consumption. Design a dashboard with the most useful information.

Cheapest Charging around

In order to develop the GIS platform of the Swiss Federal Office of Energy (SFOE) further: Add price information to the charging stations and find the cheapest option around for electric car drivers.

Energy Data Visualization    

Creating a platform for strategic decision making based on data from the Energy Science Center of ETH Zürich.

e-mobility behavior analysis

We analysed the charging patterns of private vs public e-cars charging stations. This could provide good hints for a further automated customer segmentation, help prediction of behavior changes for the load-curve vs renewable electricity production & help customers optimize their charging habits.

Empower the People with Smart Meter Data

Smart Meter Additional Use Cases: Novel energy certificate assesses where and how strongly building / user behaviour causes deviation from theoretical / optimum behaviour.

ML Wind Power-Prediction

Machine Learning Wind Turbine Power Curve Prediction: we compared constructor provided production projections with actual production curves with the goal to improve site-specific  performance prediction of wind turbines.
– Development of machine learning algorithms  (or tools/aps) for improved site-specific  performance prediction of wind turbines.
– Development of alternative algorithms e.g. Artificial Neural Networks
– Inputs: wind velocity, turbulence intensity, shear factor (alpha)

Put CH on the Electricity Map

Help meet the Paris Convention goals to achieve net 0 by 2050, less than 2 tonnes CO2 per person! We want to raise awareness around energy use and consumption by putting Switzerland on the map at and put its open data API to use.

Distributed analytics for asset management

The goal is to create a decision support tool for asset managers, using AI to predict how power transformers will fail, and what to watch out for.

Anomaly Detection in Smart Meter Data

We developed EDA and algorithms for the Anomaly Detection in Smart Meter Data challenge. We developed several approaches for detecting anomalous days based on mean and std of the readings during the day and for detecting single anomalous readings.

These models can be integrated in the second part  of the challenge

MeterOS: Smart Meter Anomaly Detection

Create a model for Smartmeter Anomaly detector and their visualization.

Unleashing the Swiss Smartmeter’s CII

Empower citizens to use their energy data. Using the smartmeter’s CII beyond visualisation to steer local consumption.We developed a concept and PoC roadmap to provide a “universal” adapter from smart meters to home IoT platforms. Forum: From Data Visions to Action Points

| 30. Sep 2020 | in Event | Keine Kommentare

Back in June we celebrated the 10th edition of our yearly forum. Where we talked about new data narratives and our visions for the data future. During the forum we held two workshops based on data visions to find concrete action points that we can do today to create a better (data) future.

New data visions

We called for our community to enter data visions which we then worked on in greater depth at the forum. From the 19 visions that were entered via our website, we selected eight to be treated during workshops. We are leaving the form open for entries, in case you would like to let us know about your data vision you can do so here.

You can find the notes on the eight workshops in the table below.

Filling Female Data GapsA world where data is available without gender bias and gaps
Research Data ConnectomeTo connect and organize (meta)data for research sustainably across disciplines, in order to make it widely accessible, interoperable and valuable.
Serving, not SpyingIn ten years from now, I don’t feel observed and manipulated through the Data being collected about me but I can rely on being served by data for better services, better policies and a better environment.
Large Citizen Generated Open Data SetsResearch institutes routinely use large open data sets, where individuals have securely donated their anonymous high quality personal data of different kinds (e.g. contact tracing data, spatial data, shopping data, media consumption, etc.)
Better use of data in Switzerland 1 Public and private sector data is open, shared, and used for public and private good within a trustworthy data ecosystem (“Swiss / European DataSpace“).
Better use of data in Switzerland 2Public and private sector data is open, shared, and used for public and private good within a trustworthy data ecosystem (“Swiss / European DataSpace“).
Solid basis for committed debate and innovationData creates a critically discussable basis for political analysis and joint shaping of our future just as they enable innovations in everyday life – free access and responsible use are indispensable for an enlightened information society.
Open decentralized data storageData is a new form of currency: It is too powerful to be controlled by centralized private entities – let’s build a decentralized system to store, share and use data.
Shared ecosystem of energy data in SwitzerlandData about energy production and consumption is shared openly by Swiss utility companies, promoting open innovation and helping to reach the “Agenda 2030” climate goals.

Defining pain points and action points

From the eight visions that were proposed at the forum, seven were treated in two workshops. Unfortunately not enough people wanted to work on the vision«Large Citizen Generated Open Data Sets». However, the vision «Better use of data in Switzerland» proved to be so popular, that we had two groups working on it. 

In the first workshop, the visions were first made more concrete, then the current situation was recorded and finally the pain points, i.e. the differences between vision and actual situation, were discussed and noted. 

Based on these pain points, the accountable stakeholders were identified in the second workshop. Then action points were noted for these stakeholders, which they can and should address.

You can read the overview of all pain points and action points here.

Pain points

The lack of data literacy was a pain point featured in most of the workshops. The lack of education on data appears to affect many areas. A further problem is the findability and accessibility of data. Even if you find a data set you need, doesn’t mean you can easily use it and integrate it into your research or project. This again is an issue that affects the whole data ecosystem. The second workshop picked up these pain points and after trying to assess the accountability for these developed several action points.

Choosing action points

Among the action points identified in the workshops, three were selected per vision and subjected to a vote on how urgently they should be tackled. Looking at the results of the voting process the following five action points appear to be the most urgent out of the 24 submitted to voting:

  1. Data Literacy: Stakeholder: Institutes and Departments & Research Support: Provide Trainings and Education Sessions. (111/135 points)
  1. Data providers: need to provide good data publication (e.g. publish high-quality data together with metadata), and secure unified open data licences. (110/135 points)
  1. Political decision makers: Provide an easy to understand  legal basis for clear data portability rules and for a decentralized data infrastructure (?). Enable (cantonal) pilots for digital participation. (108/135 points)
  1. Foster cooperation between data user and data provider. On the data user side this means  education (data literacy), good use cases und sustainable data Investment (not only Dashboards). (108/135 points)
  1. Public institutions (libraries, archives, educational institutions, data holders): Provide Infrastructure (as an alternative to Google, Apple, Facebook, Amazon, etc.) open for everybody. (107/135 points)
  1. Data producers: Be transparent about known flaws in data (it’s better to state/take on than “hide”) and actively seek feedback from data users, to provide better documentation, metadata, and to be able to curate data better. (106/135 points)

Improving data literacy, better data and documentation on it, better legal conditions, better cooperation between data users and data providers and better, more open source infrastructure, is therefore what we will be working toward in the future.  

Next steps

Thanks to the feedback we received, we are looking into ways to improve these priorities. 

If you have an idea on how to actively tackle one of the action points mentioned above or you want to start a working group around one of these topics please let us know via info { at }

On our side, we are already working on data literacy with our Data Café and school of data. We are routinely bringing together data providers and data users at our Hackdays where data providers can experience first hand how their data is being used. A guide on how to (better) publish open data is something we have been thinking about for a long time. It appears it’s not only our association that sees a need for this. We will try to find capacities not only to challenge but also to support data providers as far as that is our responsibility.

Open Farming Hackdays 2020

| 21. Sep 2020 | in Daten, Event, Food | Keine Kommentare

Vom 4. bis 5. September fanden die ersten Open Farming Hackdays am Landwirtschaftlichen Zentrum Liebegg statt.

Elf neue Lösungsansätze

In nur 36 Stunden wurden die folgenden elf neuen Prototypen für die Landwirtschaft von morgen kreiert.

Die gesunde Kuh: Früherkennung von Krankheiten zur Reduktion von Medikamenten-Einsatz.

Cow Value hilft bei der Entscheidung ob eine Kuh weiter auf dem Hof bleibt oder geschlachtet werden soll.

Decision Support Besamung hilft dabei den idealen Zeitpunkt für die Besamung einer Kuh zu finden.

DorpAdvisor empfiehlt Parzellengenau die richtige Bewässerungsstrategie um den Wasserverbrauch und den Trockenstress für die Pflanzen zu minimieren.

TRIVAtünder ist eine Austauschplattform für Hofdünger

Stop Erosion, eine interaktive Karte, zeigt auf wo das Erosionsrisiko besonders hoch ist, damit gezielte Gegenmassnahmen getroffen werde können.

Dank Open Source Felddaten können Neophyten erkannt, getaggt und automatisch auf einer Landkarte vermerkt werden.

Databndlr vernetzt Konsumentinnen direkt mit den Produzentinnen.

Farmpreneur hilft Bäuerinnen für die Zukunft zu planen

EVAS erfasst die Auslaufzeit der Kühe Automatisch und reduziert so den Aufwand der Bäuerinnen.

Mehr Biodiversität im Ackerbaugebiet zeig auf, wie man ebendiese erreichen könnte.

Begeisterte & engagierte Teilnehmende

Die Teilnehmenden hatten verschiedenste Hintergründe zum Teil ohne landwirtschaftliche Vorkenntnisse: «Motiviert hat mich, dass die zwei Bereiche Landwirtschaft und Hacking eher weit auseinander liegen und dass man daher extrem gut davon profitieren kann, wenn die zwei Bereiche näher zusammen arbeiten. Zudem habe ich keine Ahnung davon wie die Landwirtschaft funktioniert.» meinte einer der Teilnehmenden.

Eine Teilnehmerin meinte dazu: «Vom thematischen inspiriert es mich enorm was für Leute hier zusammen kommen. Es ist mein erstes Mal an einem Hackathon und mit dabei sein zu können und sich auszutauschen und zu sehen wie andere Leute arbeiten war sehr spannend.»

Markus Gusset, vom Bundesamt für Landwirtschaft, war als Challenge-Owner bei Stop Erosion dabei. 75% der Challenge hätten sie im Team lösen können. Zur Rolle von Open Data für seine Challenge meinte er: «Das war die Herausforderung. Nicht alles was wir brauchten um die Challenge anzugehen konnten wir mit öffentlich zugänglichen Daten lösen. Sogar beim Bund war es schwierig die Daten zur Weiterverarbeitung einzubinden. Du kannst sie nicht einfach weiterverarbeiten. Es gibt offene Daten die man ansehen und beziehen kann, aber man brauch zuerst eine Berechtigung für die Weiterverarbeitung. Das war eine Herausforderung für uns da man die Berechtigungen nicht einfach schnell an einem Wochenende erhalten kann.»


Open Data Stories 2019/20

| 11. Aug 2020 | in Allgemein, Daten | Keine Kommentare

Before and during the Forum we asked you to submit your open data success stories and failures. We think it is important to collect and publish these stories to show what our community has been up to, to reflect upon the successes to realise how far we have come and to think about our failures to pinpoint room for improvements.

During our Forum on June 23, we have received fourteen stories from you. If you would like to add your own story to our collection of successes, you can do so by using the following form: 2020

Findability of Open Government Data

To be valuable open (government) data has to be easily found and used a lot. Open data is published to be used and the easier it is to find a data set, the more it will be used.

Three of your stories feature the search for Open Government Data:

«With the Relaunch of the Website of the Canton of Zurich in the beginning of July 2020 all Open Government Data of Cantonal Organizations will be findable on our Website, too.»

«Road Names have been published as open data: Official index of streets (Federal Office of Topography swisstopo) Official dataset for “official index of streets”, ID196, as per the catalogue of basic geodata in accordance with Swiss Federal Law. The official index of streets includes all of the street names that have been officially declared in the Swiss Federal Register of Buildings and Dwellings (RBD). Responsibility for the completeness of the names in the official index of streets is governed by cantonal provisions.  Link: and»

«I needed a data set to practice ANOVA and went to to find one that would be suited for the task; I gave up after 90 min. I found the GitHub repository on COVID-19 data from the statistics department of the Canton of Zurich very reliable and useful for data mining.»


COVID-19 was the event that has been impacting all our lives since early 2020. The publication and use of data sets on the pandemic, as well as the fact that the importance of open data suddenly became visible is a success

«The COVID-19 data we gathered on GitHub was a huge success. It really showed the power of open data and a lot of people (including leading news outlets like NZZ and SRF) relied on that data when the BAG could not deliver. For the combination of different OGD publishers working together, joined by amazing people from the open data community to work together on this time of crisis was very inspiring. It showed, that we can “pull it off” when we have to. We were there and helped each other and created this amazing dataset for everyone to use. I think I will never forget the past 3 months and what they did to advance the open data movement in Switzerland.»

«Thanks to an excellent collaboration, we were able to open up our COVID19-data as open data much faster than expected. It was a really good example of who working together and examples of best practice helped to foster opening up data!»

«COVID-19 has raised awareness for timely, comprehensive, and machine-readable open data, which everyone is allowed to freely re-use.»

«Happy thought: the publication of data related to COVID-19 sensitized some of my friends to government data issues. In this context, it was nice to see individuals creating data visualisations for broader audiences, often during their own spare time.»

Open Data Projects

The completion of projects is of course always a success. Here are two examples of open data projects that were advanced in the past year:

«Simply generate coordinates of addresses in Switzerland and display them on a map (Success)  Calculating the coordinates of the addresses of teams, clubs, customers or any other group in a simple way and displaying the corresponding points on a map – that was the user-driven request we had again and again on 
We have created a simple Excel file that makes this possible:

  1. Download the XLSX file: 
  2. Open in Excel, follow any instructions for “Activate content”
  3. Fill in the addresses in column 1 from line 5 onwards. Click on Enter to calculate the coordinates.
  4. Select column 9 and copy the contents into a text editor – Save this new TXT file as a KML file (filename.kml)
  5. Go to
  6. and click on “Advanced Tools” on the left and then “Import”. 
  7. Click on “local” and upload your KML file. This simple file is downloaded by many government bodies, fire departments, postal service officials etc… and did not cost an hour to set up and publish on »

«I worked on quite an exciting project at the Open Tourism Data Hackdays last year which analysed the volumes of pedestrian traffic. This was exemplary both in its use of Data Science and in the way that the hackathon team – supported by the association which helped us access the data – petitions cities to implement foot traffic counters and share the data openly. This kind of analysis, by the way, was quite critical a few months later in attempting to combat the spread of COVID-19 in Swiss towns, and work on the open-source project that resulted at our Hackdays continues.  For my part, I am keen to see a #CivicUrbanism interest group start within to promote projects of this type.»


By facing challenges we always learn a lot. Here are some of the challenges you told us about:

«I have invited cultural institutions to open up some datasets, offering counsel, guidance, and practical assistance, but very few responded to my call.»

«I noticed (once again): Getting data cleaned in JavaScript is really, really hard.»

Personal growth and networking

Learning new things, making new connections, and expanding our horizons are some of the successes you shared with us. 

«I learned to work with WikiData in an introduction course by OpenGLAM and added data points regarding female directors of museums, which was fun and felt good! :) This is definitely something that I want to do more often in the future and encourage others to do as well.»

«My success story as a new specialist librarian for research data management: I got to know people who are willing to share as much of their data as possible. They want it to be citable, they want others to work on it, they want others to analyse it. Unfortunately, it became also a bit of a failure story because difficulties arose in technical issues. Where to store it, where to publish it, how to manage access. Together, I want to give them the best support and they should have the opportunity to become seen and recognized in their field by publishing data. We share a vision for that.»

«Met a bunch of inspiring people passionate about Diversity & Inclusion in Open Data at the ODF conference»

Open Data Student Awards

Of course, we also consider the entries for our Open Data Student Awards as success stories. You can read all about the past winners and nominees on our previous blog posts: 2018 | 2019 | 2020
