Building automation and control systems (BACS) are an important part of modern buildings and building automation. More and more they are also responsible for functions affecting people’s safety, security and health. Modern BACS go way beyond trivial control or measurement tasks, their importance for the processes f a building (climate, safety, logistics, etc.) is constantly growing. The respective technology is therefore supposed to work reliable, secure, safe, robust and efficient. These equipments are comprised by the key word dependability. To effectively fulfil the markets drive towards higher dependability of BACS a neutral definition of dependable BACS is needed.
This document standardizes the base not only to use BACS for safety, non-safety, and security functions but also to integrate these functionalities in a single dependable BACS. E.g. the integration of smoke detection and heating radiator control will not only reduce installation costs since only on BACS is needed it will also allow for advanced safety functions such as turning of the heating if smoke is detected. Hence a fire will not be fuelled.
The scope of this document will focus on the properties of the BACS to maintain their today’s flexible utilization in a dependable way. It will not focus on particular applications. Normative references already available will be used when applicable and completed by missing requirements for dependable BACS including metrics to define the level of dependability. A special focus is related to the commonalities between he development of safety and security systems to benefit from commonalities in development and the live cycle.
