Use of the TQB building assessment system is free.  To make full use of it, including transfer and saving the building assessment, registration as ASBC consultant is required.

The general procedure calls for building documentation using online declaration tools carried out by an approved ASBC consultant.  The project and application for building surveying must be submitted to the ASBC.

The TQB building assessment system is made available to the ASBC by the Austrian Institute for Ecology – Österreichisches Ökologie-Institut – and the Austrian Institute for Building Biology and Ecology – Österreichisches Institut für Baubiologie und ‑ökologie, which are also ASBC founding members.
