Digital Twin
Digital Twin is a virtual model of a physical object, system or process that is continually updated based on real data. Such models are usually built on sensor data, information system data, historical indicators and simulations. In other words, it is not just a static drawing or 3D image, but a living digital representation that helps us better understand what is happening in reality.
In the public sector, the digital twin principle is becoming increasingly relevant, as municipalities, schools, museums, libraries and other organisations are looking for ways to make decisions based on data. Such a model can help monitor infrastructure condition, plan changes, assess risks and model different scenarios in advance. It is particularly useful where efficient use of resources, service quality and long-term planning matter.
How does a digital twin work?
A digital twin usually combines several layers: the physical object or process, data collection, analysis and visualisation. For example, sensors installed in a building can transmit information about temperature, humidity, energy consumption or people flows, and the system displays this data in a digital model. This makes it possible not only to see the current situation, but also to predict possible disruptions or assess how results would change if one or another decision were taken.
It is important to understand that a digital twin is not only a technological solution. Its value becomes clear when data is useful in day-to-day operations: planning repairs, managing energy consumption, organising visitor flows or optimising administrative processes. Therefore, successful implementation requires not only technical infrastructure, but also clear objectives, responsibilities and data management procedures.
Application in municipalities and public bodies
In municipalities, digital twins can be used for city planning and infrastructure management. For example, when modelling traffic flows, it is possible to assess how movement would change if junction control were altered, new parking spaces were installed or public transport routes were reorganised. This allows decisions to be made not only on assumptions, but also after testing possible impacts in advance.
In the management of public buildings, a digital twin can help monitor energy efficiency, the operation of heating and ventilation systems, room occupancy and technical condition. For schools, this is relevant when planning classroom use, ensuring a comfortable environment for pupils and staff, and reducing operating costs. In libraries or museums, such a solution can be useful for managing the microclimate, protecting exhibits, planning visitor flows and ensuring a more convenient visitor experience.
A digital twin can also be applied in service processes. For example, a local authority can model the flow of resident service, document movement or registration processes before introducing changes. This helps to identify possible disruptions in advance, reduce queues and plan staff time better.
Main benefits
- Better decision-making. A digital twin makes it possible to see not only the current situation, but also possible future consequences. This is particularly important in the public sector, where decisions often have a long-term impact on the community and infrastructure.
- More efficient use of resources. With a more accurate picture of how buildings, systems or processes operate, it is easier to plan maintenance, repairs and energy use. This helps to use the budget more rationally and reduce unnecessary costs.
- Risk reduction. By modelling different scenarios, weak points can be identified earlier and preparations made for possible disruptions. Such an approach is especially valuable when managing critical infrastructure or planning major organisational changes.
- Clearer communication. Visual models help explain planned decisions more simply to politicians, administration, the community or organisation staff. This is important when investment needs to be justified or stakeholders need to be involved in decision-making.
Accessibility, data protection and compliance
When implementing digital twin solutions in the public sector, it is important to assess not only technological functionality, but also accessibility. If model data or visualisations are provided to staff or residents via websites or self-service systems, they must be understandable, easy to use and adapted for users with different needs. This means a clear structure, appropriate contrast, keyboard navigation and compatibility with assistive technologies.
Compliance with GDPR requirements is no less important. If a digital twin uses data that may be linked to individuals, for example information on staff movement, registration or visitor flows, the purpose of data processing, legal basis, retention periods and access rights must be clearly defined. For public bodies, it is important to ensure that only necessary data are processed and that the solution is secure and transparent.
Integration with already used systems and overall compliance management are also relevant. For municipalities and public bodies, it is important that new solutions work well with document management, asset accounting, booking or other information systems. The better the architecture is thought through, the easier it is to ensure the long-term sustainability of the solution.
When is it worth considering a digital twin?
It is worth considering a digital twin when an organisation manages complex infrastructure, has many different data sources or wants to base decisions not only on intuition. This may be relevant for a municipality planning the development of urban areas, a school seeking to manage a building more efficiently, or a museum that needs precise control of environmental conditions. Even in smaller organisations, digital twin principles can be applied in stages, starting with one process or object.
A digital twin is not just a technological innovation. It is a practical tool that helps public-sector organisations better understand their operations, plan changes and create more reliable, more efficient services for residents. Properly implemented, it can become an important part of digital maturity – especially where transparency, accountability and long-term value for the community matter.
