Energy & Climate Hack

- May 27, 2021 in Bern, Climate, Daten, Energie, event, Forschung, hackathon, International, smart city

There’s no need to emphasize the need for action and innovation against climate change.
Transport, production, from habitat to consumption… around 70 % of global CO2 emissions are linked to the activities in cities.  The Energy & Climate Hack will take place in the city of Berne on August 31st and September 1st 2021, as a parallel event to the Decarbonizing Cities Conference. This hackathon throws a bridge between common issues and needs across borders and will bring together students from the United Kingdom and Switzerland as well as experts,hackers and people aspiring to make a difference. The multidisciplinary teams will look at smarter urban living through the lenses of energy efficiency and research for better decision making. The beauty of this event is not only that it will allow us to explore new solutions, but also that it exemplifies how bottom-up locally embedded initiatives tackle global issues and how these proposals, tested at a local scale, can help our society beyond their original purpose. This event is organised in collaboration with Swisspower and the British Embassy in Berne. It is open and free of charge, like all our other hackdays.
Please register until the August 17th 2021 and take part: you too can help shape the cities of the future!Find out more on

Shape My City – Lucerne, the Results!

- January 19, 2021 in Bildung, Daten, Energie, event, Forschung, hackathon, Luzern, smart city

Almost in the same breath, following the Smart city Lab Lenzburg, we were happy to support the student team of the Master of Applied Information and Data Science at the HSLU in their organization of the Shape My City Hackdays – Luzern, a Hackathon revolving around smart city projects for Lucerne and its inhabitants. Around 110 participants gathered online, ready to hear about the 15 so-called challenges awaiting for a solution. Those issues opened by either the industry, civil society or city of Lucerne itself, were prepared in collaboration with group of students who helped defining the framework of the question and to gather and prepare relevant datasets, providing the Hackdays-teams with the material to solve the challenge itself. This event being a fully virtual workshop was not as vividly alive as what we are used to during the HSLU-student Hackdays, (melancholy…), still, the very funny slides and the clear engagement of the teams made for a very good event. Two inputs by Stefan Metzger CDO of the city of Luzern and by Benjamin Szemkus, Program manager of Smart City Switzerland, provided for background information about the strategies and perspective in the field. A lot of open data on the topic of smart cities was gathered, and last but not least and as always astonishing, the plethora of good results convinced us once again of the relevance of such collaborative endeavours. The challenge topics nicely completed or confirmed those issues addressed a few weeks before in Lenzburg. There too it was obvious that those location and user-specific solutions are actually relevant for a much broader public and regions. Nevertheless, implementing them locally still seems to be a meaningful and challenging enough step before exploring those broader fields. Most teams are willing and ready to keep on exploring the challenges with their challenge owners, we are curious to see how far the projects go from there on! Solar Energy in the City of Lucerne
Identifying similar buildings in terms of solar characteristics facilitates the approach to building owners to promote the installation of solar panels. The project group gathered over 15 different datasets, cleaning, preprocessing, analyzing and converting the datasets into desired shapes and Geospatial data formats. The prototype is as desired simply an excel file, containing the necessary information.  Disclaimer: data about the buildings are not publicly available and are to be considered as strictly confidential. Therefore, this part is private, however, the code is public. Consumer Behavior in the City of Lucerne
The project group worked on identifying Personas that will help to address the target groups on the topic of environmentally friendly behaviours. They also worked on analysing datasets to find interesting correlations and patterns concerning existing consumer behaviour. Quantification of Visitors of Cultural Events
The number of visitors from the surrounding municipalities attending events at cultural venues in Lucerne is not available yet. The project-team created a measurement tool that easily and efficiently registers the place of residence of the attendees of a cultural event. Drug Sharing Ecosystem Driven by Blockchain
This group implemented a Blockchain technology to visualizes exchanges and flows of drugs between main health stakeholders, in order to increase transparency, security and automation of drug exchanges. Open Social Spaces
Through the use of a web AR Application, locals can give a shape to their ideas. Users can place and visualize objects directly in a chosen location and vote for creations by others. 360° Stakeholder Feedback Analysis
Large urban transformation projects require thorough analysis of the needs and requirements of all stakeholders involved. This project-team therefore worked on a Dashboard allowing grouping, qualification and prioritization of the stakeholders-related needs and information, in order to make more of the available data and provide decision-makers with a fast overview by project.
2000 Watt Site – Reduction of Energy Consumption
This project-team worked on a gamification model and an app to inform and incentivize the reduction of energy consumption of households and help achieve the 2000 Watt Society goals. The system aims to compares households’ consumption as awareness is one of the motivations for new energy consumption strategies. Reduce Car Rides at Traffic Peak Hours
The project-team worked with an Agent-Based Traffic Modelling and Simulation Approach to predict and analyse the forseeable changes in traffic load for an area in planning.
They produced a SUMO file with a modeled traffic flow integrating the new conditions on the project site, as well as reflected on the tools and incentives for future traffic regulation on the area. Find Energy Inefficient Buildings in the City of Lucerne
As about 45 % energy usage is for buildings this team worked on a building-images database to identify potentially energy-intensive buildings, as well as on a gamified app-prototype to improve the quality oft he image collection, labelling and identifying thanks to collective intelligence. Interactive Visualizationfor Neighbourhood Residents
This team worked on visualizing existing data of small sub-quarters to gain insights about the facts, needs and participation interests of the residents in those neighbourhoods. The insights and visualisation will be integrated in the website to make the findings accessible to all residents. 3D Geovisualization of building energy demands
In order to identify strategic leverage areas of high energy consumption, this team combined 3D data with energy demand data and revealed regions and buildings with potential for energy optimisation. Flat finder for seniors:
This team tackled the issue of the specific needs of the elderly when it comes to finding a suitable house or apartment. They created a housing platform that analyses housing advertisements from existing platforms and filters out those fitting the needs of seniors. Netto- Null in den Quartieren?
The demo created by this group allows to determine the current CO-2 emissions in the districts of Lucerne and to visualise which heating methods the buildings are using. This is a strategic information for decision makers for energy production methods and for the inhabitants to visualize the impact of one or the other heating system on the environment.

Quality of Life in Lucerne
This working group focussed on generating new insights from an online questionnaire about Life quality in Lucerne for the city administration. They identified personas, expectations and new variables from the citizens answers.

Energy Data Hackdays 2020, the results!

- October 6, 2020 in 2020, Brugg, Daten, Energie, Energy, event, Forschung, hackathon, Hackdays, machine learning, Optimization

The excitement of 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.

How to deal with IP rights of growing projects and products at hackathons – experience from the Japanese context

- February 28, 2019 in hackathon, IP, japan, OK Japan, Open Data Day, tools

Ahead of Open Data Day on Saturday 2nd March 2019, Tomoaki Watanabe from our Japanese chapter Open Knowledge Japan shares more information on a tool they developed to facilitate dealing with intellectual property (IP) rights during hackathon events. This year, many Open Data Day events are planned in Japan: Open Knowledge Japan created an overview at The main idea is simple: a tool to facilitate consensus formation on the intellectual property (IP) rights in the materials generated out of a hackathon. That is so that interested participants, or even others, know that they can develop a promising project further after the event is over. You would see many gems generated at a hackathon: interesting projects, promising products and services, inspiring ideas, sketches, mockups and so on. The excitement and the passion it produces may fade away over time. And sometimes, you may be disappointed by the fact that a seemingly promising project does not get anywhere, even when there are some people who want to develop it further. It is just that the one who wants to carry on cannot figure out if doing so is okay. Another problem related to the rights and licenses issue happens when a for profit company hosts a hackathon and claims all the IP rights – this may make some participants feel surprised and exploited. In Japan, a research project related to digital fabrication <> saw this problem and came up with a rather simple set of templates, called “a participation agreement,” <> to facilitate and document participants’ consensus on the rights issues around hackathons or makeathons. (Disclosure: I am currently a member of the research project, although I am not one of the members who developed it.) It has been developed with the help of a lawyer to ensure proper legal force. The main developer helped introduce them to well over a dozen hackathons and similar events, and a small study found that all private and public sector organizers knew about the tool (Kobayashi & Mizuno, 2016). The tool is published under an open license (CC-BY-SA 4.0), and meant to be customized by the organizer(s) of the event adopting the tool.

How to Use and Major Features

The tool is a set of documents. The Participation Consent Form is like a terms of service for the event, so that the participants know, prior to the event, what happens to his rights. The Post-Event Confirmation Form is to be agreed after the event. The “default settings” of the documents are such that participants’ intellectual property rights stay with participants. The exception is when a participant becomes unreachable, in which case his rights are deemed waived. It means that, at least, participants can explore what to do with the unfinished project and negotiate over the terms. Additionally, it has a clause stating that contributing ideas alone would not result in any ground for an IP right. These settings are in the pre-participation document, and the post-participation document is for writing down an agreement among the contributing group members over their rights, permissions, terms, etc. so that they know what they can do with the output of their team. One important “default setting” there is the statement that those who do not participate into commercialization after the event will waive all their IP rights. Some organizers may think that some revenue sharing scheme or acknowledgement of contribution (attribution / crediting) should be adopted as a default. In order to customize the documents, a good starting point would be to change the very first part – from title, organizer’s name, and to Art. 1, which is about the purpose of the event. Another section to customize may be the Art. 2, where the IP rights are discussed. If a Creative Commons Attribution license (CC-BY) should be adopted as a baseline for copyrights in participants’ contributions, for example, this would be a good place to state that. Art. 2 of the post-event document has the “default setting” mentioned above on non-participating members of post-event commercialization waiving the IP rights. One additional thing to note is that because the tool was originally developed for Japanese context, they contain references to the Japanese copyright law. There is a repository at GitHub so that people can report suggestions, bugs or questions. Forking the tool is also welcome, according to a Japanese material by the developers. To recap, these documents (templates) are good for avoiding the avoidable rights-clearance issues arising out of collaborative events like a hackathon.   Reference: Kobayashi & Mizuno (2016). “Making rules regarding intellectual property rights at co-creation events such as hack-a-thons: proposal of a participation agreement.” Digital Practice, v.7, n.2, pp.128-135.
