Abstract (De)
Building automation (BA) systems orchestrate and monitor the functioning of
a wide variety of utilities in a building so that living spaces are kept comfortable,
safe, and secure. The complexity of such a system which involves multiple
disciplines (heating, air-conditioning, lighting, fire safety, security etc.), coming
from multiple vendors, is compounded by the fact that each building differs in
the way the equipment operate and coordinate.
So far, efforts involving semantic modeling of BA systems, like Haystack
[3], IFC [2], or Brick [1], have been focusing on the description of the building
topology, installed equipment, and to a lesser extent, the control strategy, the
modeling of the physical process and the role of the control program. In addition,
the semantics of interaction with the devices used in BA, which is essential
to establish technical interoperability, has so far not been coupled to the BA
semantic models. As a result, planners, project engineers, technical operators,
and service technicians have to design and understand the working of the system
by piecing together information from different sources.
From our experience at the Smart Infrastructure division of Siemens AG, we
describe briefly in the following sections some key use-cases, the challenges faced
by us while applying semantic data in BA, and finally describe our approach
and its evaluation in real-life buildings.
