WELCOME
The European Building Database provides a harmonised, EU-wide view of building information that can support modelling, planning and simulation across urban domains.
Within the EU LDT Toolbox, it helps cities work with a more consistent and reusable building data layer, reducing fragmentation and making building-related analysis easier to connect with wider Local Digital Twin workflows.
THE CHALLENGE
Across Europe, building-related data is widely available but remains fragmented, inconsistent and difficult to reuse. It is often distributed across multiple systems, formats and governance levels, making it challenging for cities to obtain a clear and reliable view of their building stock.
This lack of consistency limits the ability to connect building data with key urban challenges such as energy efficiency, sustainability and spatial planning. As a result, cities face significant barriers when developing Local Digital Twins or performing integrated analysis, slowing down data-driven decision-making and innovation.
HOW IT WORKS
The European Building Database brings together building information from multiple trusted sources into a harmonised and interoperable dataset. This makes the data easier to use across different urban workflows without forcing each city to rebuild the same data foundations from scratch.
In the Toolbox context, the database functions as a common reference layer. It supports the preparation of building-related inputs that can then be linked to planning, modelling and simulation processes in broader Local Digital Twin environments.
The European Building Database gathers building-related information from a variety of existing and trusted sources, including public registries, local datasets and external providers. This step focuses on bringing together dispersed data into a single entry point, reducing fragmentation and ensuring that relevant information is accessible for further processing
Once collected, data is aligned into a common structure based on shared standards. This process ensures consistency across different formats, definitions and levels of detail, allowing data from different cities or countries to be comparable and interoperable within the EU LDT ecosystem.
Harmonised building data is then integrated with other datasets and tools within the EU LDT Toolbox. This enables building information to be linked with broader urban domains such as mobility, energy or environment, supporting cross-domain analysis and more comprehensive urban modelling.
Finally, the structured and connected data can be used in planning, modelling and simulation processes. It supports Local Digital Twin workflows by providing reliable inputs for scenario analysis, helping cities explore potential interventions and make more informed, evidence-based decisions.
INTEGRATION WITHIN THE EU LDT TOOLBOX
The European Building Database strengthens the Toolbox by making building-related information easier to access, connect and reuse across interoperable urban workflows.
WHY IT MATTERS
The European Building Database provides a shared, harmonised foundation for building-related data across Europe, enabling cities to work with more consistent, comparable and reusable information within Local Digital Twin workflows.

KEY CAPABILITIES
The database supports a view of the physical and structural dimension of buildings, helping create a clearer description of the built environment.
It includes energy-related attributes that can support broader sustainability and planning analysis within Local Digital Twin contexts.
Occupancy-related information helps add another layer of understanding to how buildings function in practice within urban systems.
Environmental attributes support a more complete picture of how building information relates to wider urban modelling and planning needs.
By combining these dimensions in a harmonised way, the database contributes to planning and simulation across urban domains.
