Abstract:
A method is presented to compare different co-simulation interfaces and applied to a case study of thermal
engineering. Different interfaces providing loose and strong coupling based on the Functional Mockup Interface
(FMI), the Building Controls Virtual Test Bed (BCVTB) and a Component Object Model (COM)
are compared with respect to user-friendliness and flexibility, computational costs and accuracy. The case
study considered includes a compact thermal energy storage modelled in Trnsys and a heat sink modelled in
Simulink. The implemented strong coupling scheme is a factor of 10 more accurate while a factor of almost
100 computationally more demanding than the loose coupling one.
