Référentiel National des Bâtiments

Contexte

The National Building Registry (RNB) is a digital public service designed to create a new national reference dataset for buildings — a dataset that did not exist until now, yet is essential for implementing numerous public and territorial policies.
To achieve this, it catalogs all buildings across the country and assigns each a unique identifier.
This 'building license plate' aims to simplify the monitoring of changes in the building stock and to facilitate the cross-referencing of various building-related data useful to public administrations, local authorities, and private stakeholders

Acteurs

The RNB is jointly supported by the French Agency for Ecological Transition (ADEME), the Scientific and Technical Center for Building (CSTB), the General Directorate for Planning, Housing and Nature (DGALN), and the National Institute of Geographic and Forest Information (IGN).
The service is developed by a State start-up incubated within the 'Fabrique de la donnée territoriale', the IGN's territorial data incubator.
The construction of the RNB is also carried out in collaboration with geomatics data experts from the National Council for Geolocated Information (CNIG)
