Building automation and control systems (BACSs) are a tool for operating, setting, switching, controlling, regulating, monitoring, evaluation and optimisation of building services. BACSs provide information technology support in the context of the processes of operation and maintenance of building services and is thus part of the computer-aided facility management (CAFM). However, BACSs themselves need the maintenance of their hardware and software. The standard gives instructions for operation of buildings by means of a BACS and the maintenance of the BACS itself.
