The EU Building Stock Observatory (BSO) has undergone the most substantial upgrade since its inception in 2016. In March 2024, the European Commission launched a new version that offers an improved user interface and more data availability.

The main improvements include an increased dataset with additional indicators and a higher level of detail and a new user interface that offers advanced user experience. Thanks to these changes, users can also customise data visualisations and compare different sets of data, making more combinations between available indicators possible.

Information about occupancy, tenancy type and social aspects related to energy poverty are some examples of what is included in this expanded data set.

With these major upgrades, this open-source web platform on building’s energy performance in the EU, is ready to become the central data hub on the European building stock, specifically under the new Energy Performance of Buildings Directive.
