Modelling and simulation of standardised control functions from building automation

Despite the accepted fact that control logic deployed in future and existing buildings through building automation systems constitutes a keyfactor for increasing their energy efficiency, the support for modelling and simulation of these in current state-of-the-art simulation tools and libraries is rather limited. In particular a gap exists for modelling and simulation of standardised control functions. In this work we present an approach for modelling standardised control logic using Modelica. We evaluated the interoperability of the modelling approach by simulating a testcase of an automation solution controlling the sunshade of a room and by reimplementing a state-based control for an airhandling unit reusing models from two Annex60 compliant libraries.
