Simulation speedup techniques for computationally demanding tasks

Summarization: The computational cost for the repeated evaluation of zonal-type building simulation models can be pro- hibitive especially in contexts, such as Building Opti- mization and Control Design, where repeated evalua- tion of the models — for different initial and bound- ary conditions — is required. In the present paper, two techniques to reduce simulation time are investi- gated: (i) geometry simplification for periodic geome- tries; and, (ii) the use of co-simulation to split a build- ing into simpler sub-buildings, that can be evaluated in parallel, exploiting the resources of multi-core compu- tational architectures. These simulation speed-up ap- proaches are evaluated, with respect to accuracy and computational effort, against the validated full-scale models of two real buildings.Παρουσιάστηκε στο: 13th Conference of International Building Performance Simulation Associatio
