6.1.2.23 IfcWindowTypePartitioningEnum

This enumeration defines the basic configuration of the window type in terms of the number of window panels and the subdivision of the total window as shown in Figure 160. The window configurations are given for windows with one, two or three panels (including fixed panels).

Windows which are subdivided into more than three panels have to be defined by the geometry only. The type of such windows is USERDEFINED.

HISTORY  New Enumeration in IFC4. The new IfcWindowTypePartitioningEnum replaces the use of IfcWindowStyleOperationEnum that is deprecated from IFC4 onwards.

Enumerated Item Definitions:

Enumerator Description Figure
SinglePanel Window with one panel.
DoublePanelVertical Window with two panels. The configuration of the panels is vertically.
DoublePanelHorizontal Window with two panels. The configuration of the panels is horizontally.
TriplePanelVertical Window with three panels. The configuration of the panels is vertically.
TriplePanelHorizontal Window with three panels. The configuration of the panels is horizontally.
TriplePanelBottom Window with three panels. The configuration of two panels is vertically and the third one is horizontally at the bottom.
TriplePanelTop Window with three panels. The configuration of two panels is vertically and the third one is horizontally at the top.
TriplePanelLeft Window with three panels. The configuration of two panels is horizontally and the third one is vertically at the left hand side.
TriplePanelRight Window with three panels. The configuration of two panels is horizontally and the third one is vertically at the right hand side.

Figure 160 — Window partitioning

NOTE

  1. The way how each panel operates is defined at the IfcWindowPanelProperties.OperationType.
  2. The reference from the window panel to the location of that panel in the window style configuration is handled by the IfcWindowPanelProperties.PanelPosition.
  3. The figures are shown as elevations in the XZ plane of the local placement of the window, looking into the direction of the positive Y axis.
  4. These figures are only shown as illustrations
