modelSingleZoneFloor
Model of a building floor as a single zone
Information
This model assumes a mid-floor of a building as a single zone with a homogeneous temperature; i.e., the air in the whole floor is assumed to be fully mixed.
The geometry, materials and constructions of the model are consistent with those of Buildings.Examples.VAVReheat.BaseClasses.Floor, which models the same mid-floor as five zones: a core zone and four perimeter zones.
The internal partition walls in the five-zone floor model are considered as thermal mass in this single-zone floor model. The doors in the five-zone floor model have been removed in the single-zone floor model.
