This example illustrates the use of AixLib.ThermalZones.ReducedOrder.RC.FiveElements. Parameter set is for a single family building with three zones, one heated and two unheated. They are connected with interzonal elements. The building and the boundary conditions represent the building of variation D as produced by example 11 in TEASER and as presented by Philip Groesdonk et al. at the International Modelica Conference 2023 (DOI:10.3384/ecp204577).
