The National Register of Buildings and Dwellings (RBD) has been in service since January 2002, and is administered by the Swiss Federal Statistical Office (FSO) in close cooperation with the cantons and municipalities.
The RBD includes all buildings which are used totally or partially for habitation and also details of the dwelling places within. Every building and dwelling in the RBD is allocated a nationwide-unique and unambiguous identification number (EGID and EWID respctively). In addition to this number, basic data on age, size, power supply, etc. are recorded in the RBD.
The original data for the RBD were extracted from the housing census, which was part of the population census in the year 2000. Updating data for the RBD were compiled by the construction authorities within the scope of the annual construction statistics.
