Professor Hubert Klumpner’s chair designed the first AI-supported\u00a04D model for Sarajevo.

\u201cArchitecture can\u2019t wait,\u201d says Hubert Klumpner. The ETH professor and his team at the Chair of Architecture and Urban Design research, plan and build in places that, after crises and conflicts, use the opportunity to reinvent themselves as a city and society. In the Colombian city of Medell\u00edn, which was once one of the most dangerous places in South America. In Kigali, Rwanda, where a civil war was taking place. Or in Sarajevo, the capital of Bosnia and Herzegovina, which resisted the siege for 1,425 days. \u201cWe work on real-world problems and recognize the opportunities in places that lie outside the usual debate about western cities,\u201d says Klumpner.<\/p>\n

The last version of the master plan for Sarajevo dates back to 1984, when the Winter Olympics were held in the city. The \u201cUrban Transformation Project Sarajevo\u201d designs a perspective for the development of the city up to 2040. Involved are together with Klumpner’s professorship, the Laboratory of Energy Conversion of Professor Abhari at D-MAVT, the ETH spin-off SwissAI, the University of Sarajevo, the Planning Office of the Canton of Sarajevo and the City of Zurich. The project is part of a long-term collaboration with the State Secretariat for Economic Affairs SECO, which supports Klumpner’s research work in South America, Africa and, since 2018, in the Balkans.<\/p><\/div>\n

In order to better understand Sarajevo, Hubert Klumpner’s professorship, led by post-doc Michael Walczak’s research group, has designed the first computer-aided 4D model for the city and canton of Sarajevo. It combines quantitative and qualitative data to make complex planning decisions. Researchers in Sarajevo collected the data for this city’s first Digital Twin using a mobile laboratory called \u201cStudio Mobil\u201d.<\/p>\n

The result is a \u201cdigital urban imaginarium\u201d of the built and natural environment. It contains information on infrastructure, mobility, energy, water, air and soil quality, but also on people’s behavior and demographics. \u201cIn order to be able to map the complexity of the city, we need new methods, processes and technologies,\u201d says Klumpner.<\/p>\n

The Digital Twin connects different scales and takes topography, climate, every building and every vehicle into account. The model depicts energy consumption at any time of the day and night in order to be able to represent the behavior of people in the city. They are depicted as \u201cagents\u201d in the model with the help of machine learning algorithms. In this way, the simulation can understand how individual people move, where they live, and how they work.<\/p>\n

The digital twin includes the built and natural environment, but also social scientific data such as the diverse cultural, ethnic and religious characteristics of different neighborhoods. In addition to the spatial dimension, the multidimensional plan takes into account the temporal dimension in urban planning. For example, every single second of traffic behavior can be tracked and visualized in real time.<\/p><\/div>\n

The researchers do not blindly trust the digital data; the simulations were checked and calibrated on site. The \u201cStudio Mobil\u201d was present at strategic locations in the nine city districts for public hearings. At the same time, a cartography of wind movements was created and traffic behavior was recorded. In this way, research combines quantitative and qualitative data and empowers the population in the process. \u201cWe are not planning a smart city, we are working with smart people on the future of their city,\u201d says Klumpner.<\/p>\n

Until now, the city was thought of as a linear structure along a one-way street in a river valley. The new master plan describes the urban development around the city hill as a green heart. It focuses on the cross-relationships in the valley and also takes into account the hillside settlements, where 40 percent of the population lives. Sarajevo is currently one of the ten cities in the world with the worst air quality. The plan calls for non-fossil energy sources for transport and heating. In addition, the forest areas should be protected and regenerated in order to improve the air quality in the city.<\/p><\/div>\n

The cantonal planning office is already using the Digital Twin to implement alternative urban planning. The digital model is not a fixed plan, but a planning tool for decision-making. It links various parameters and thus reflects the complexity of an urban structure. And with the twin, planners can simulate scenarios and see how, for example, a new road will affect traffic flow or air quality.<\/p>\n

The Digital Twin was the basis for public hearings, which are required by law for planning in Bosnia and Herzegovina and which took place until the end of April. The researchers speak of \u201cbottom-up simulations\u201d. To make the Digital Twin more accessible, they built a physical model of the city overlaid with projections. A web-based model allowed people to participate remotely. Some key locations in the city were animated on a 1:1 scale in order to convey them clearly.<\/p><\/div>\n

The events took place in all nine municipalities of Sarajevo, and their input is now being incorporated into the model. An accompanying exhibition is currently touring the six Western Balkan states and will be on display at the Museum of Applied Arts in Belgrade from February 2025.<\/p>\n

In 1984 the Winter Olympics took place in Sarajevo. The war raged from 1992 to 1995. Today, almost 30 years later, the city has changed. At the end of April, 18 mayors from Ukraine visited Sarajevo to find out how a city can reinvent itself after a state of war – supported with new digital planning tools.<\/p><\/div>\n

The Learning & Teaching Fair 2024 brings together 42 innovative teaching projects at ETH.\u00a0This also includes the \u201cHack Archthon\u201d<\/a>, which Hubert Klumper\u2019s chair organized in Sarajevo in the spring semester of 2024. Students spent a week programming tools to visualize the data of the Digital Twin. In the end, the best performers were awarded an Olympic medal. ETH supported the teaching concept with an Innovedum grant.<\/div>\n
