Who uses it?

Usage is split 60:40 between advanced design practices (along with consultancies, developers and building owners) and researchers.

The method originated in 1985, and has been used by over 200 organisations worldwide. Licensing has been in operation since 1995.

The method is either licensed by third parties or used in-house.

Most outputs are not in the public domain. A notable exception is the series of Probe post-occupancy studies, which used the BUS method under licence.

About half the buildings on the dataset are in the UK and Ireland. The rest are spread over 16 other countries.
