Abstract

Real estate typically contain various systems that enable monitoring and controlling different building functions within them (e.g., heating). Sweden's municipalities play a central role in the management of real estates. Municipalities owns buildings and are to a large extent responsible for the procurement, installation and operation of the building automation systems. However, the understanding of how building automation is implemented in the municipal context is limited. This report describes case studies of three municipalities of different sizes that have chosen different approaches for how to monitor and control their building automation systems. It is described how the municipalities have chosen to organize themselves and what IT equipment, as well as physical and logical network architecture, they use. There are both similarities and differences between the municipalities. However, the limited sample size makes it difficult to make any general conclusions regarding building automation systems used within Swedish municipalities. The results include a draft of a reference model that describes the physical and logical topology of how municipal building automation systems are designed. The reference model is intended to be used as a tool in the dialogue between MSB and municipalities regarding discussions of IT security in industrial monitoring and control systems that are part of building automation systems.
