6.1.3.16 IfcDoor

6.1.3.16.1 Semantic definition

The door is a built element that is predominately used to provide controlled access for people, goods, animals and vehicles. It includes constructions with hinged, pivoted, sliding, and additionally revolving and folding operations. A door can:

There are two main representations for door occurrences:

  • IfcDoor entities that have a 3D rectangle 'Profile' shape representation defined. This profile can then be used to parametrically generate the geometry of a door. If not provided, the profile of the IfcOpeningElement can be used if the door fills an opening. The parameters are specified on the relating IfcDoorType that references IfcDoorLiningProperties and IfcDoorPanelProperties for each panel in the door;
  • IfcDoor entities that are not parametrically generated and have only 'Brep', or 'SurfaceModel' geometry.

In addition, an IfcDoor may commonly include a 'FootPrint' representation defining the 2D shape of the door and its swing.

The parameters of a door are defined by both the IfcDoor occurrence and its IfcDoorType. The IfcDoor specifies:

  • the door width and height
  • the door opening direction (by the positive y-axis of the ObjectPlacement)

The IfcDoorType specifies parameters which are common to all of its occurrences of IfcDoor:

  • the operation type (single swing, double swing, revolving, etc.)
  • the door hinge side (by using two different styles for right and left opening doors)
  • the particular attributes for the lining by the IfcDoorLiningProperties
  • the particular attributes for the panels by the IfcDoorPanelProperties

Door Attributes General

The opening direction is determined by the local placement of IfcDoor and the OperationType of the IfcDoorType.

The IfcDoorTypeOperationEnum defines the general layout of the door type and its symbolic presentation. Depending on the enumerator, the appropriate instances of IfcDoorLiningProperties and IfcDoorPanelProperties are attached in the list of HasPropertySets. The IfcDoorTypeOperationEnum mainly determines the hinge side (left hung, or right hung), the operation (swinging, sliding, folding, etc.) and the number of panels.

There are different definitions in various countries on what a left opening or left hung or left swing door is (same for right). Therefore the IFC definition may deviate from the local standard and needs to be mapped appropriately. Example mappings are shown in Table 6.1.3.16.M, where it assumes that the 'inside/private/primary' space is above (top in the pictures) and the 'outside/public/secondary' space is below (bottom in the pictures).

Opening Definitions US Mapping German Mapping
fig 1
Figure 6.1.3.16.D
The door panel (for swinging doors) opens always into the direction of the positive Y axis of the local placement. The determination of whether the door opens to the left or to the right is done at the level of the IfcDoorType. Here it is a left side opening door given by IfcDoorType.OperationType = SingleSwingLeft LEFT HAND (LH) DIN-R (right hung)
fig 2
Figure 6.1.3.16.E
If the door should open to the other side, then the local placement has to be changed. It is still a left side opening door, given by IfcDoorType.OperationType = SingleSwingLeft RIGHT HAND REVERSE (RHR) DIN-R (right hung)
fig 3
Figure 6.1.3.16.F
If the door panel (for swinging doors) opens to the right, a separate door style needs to be used (here IfcDoorType.OperationType = SingleSwingRight) and it always opens into the direction of the positive Y axis of the local placement. RIGHT HAND (RH) DIN-L (left hung)
fig 4
Figure 6.1.3.16.G
If the door panel (for swinging doors) opens to the right, and into the opposite direction, the local placement of the door needs to change. The door style is given by IfcDoorType.OperationType = SingleSwingRight. LEFT HAND REVERSE (LHR) DIN-L (left hung)

Material Set General

This concept can be applied to the following resources:

  • Lining - Indicates that the material constituent applies to the door lining.
  • Framing - Indicates that the material constituent applies to the door panel(s); if not provided, the 'Lining' material information applies to panel(s) as well.
  • Glazing - Indicates that the material constituent applies to the glazing part.
Product Local Placement General

The following restriction is imposed:

  1. The PlacementRelTo relationship of IfcLocalPlacement shall point to the local placement of the same element (if given), in which the IfcDoor is used as a filling (normally an IfcOpeningElement), as provided by the IfcRelFillsElement relationship;
  2. If the IfcDoor is part of an assembly, e.g. an IfcCurtainWall, then the PlacementRelTo relationship of IfcLocalPlacement shall point (if given) to the local placement of that assembly;
  3. If the IfcDoor is not inserted into an IfcOpeningElement, then the PlacementRelTo relationship of IfcLocalPlacement shall point (if given) to the local placement of the same IfcSpatialStructureElement that is used in the ContainedInStructure inverse attribute or to a referenced spatial structure element at a higher level.
Profile 3D Geometry General

The door profile is represented by a three-dimensional closed curve lying in the xz plane. The profile is used to apply the parameters of a parametric door representation. The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

  • RepresentationIdentifier: 'Profile'
  • RepresentationType: 'Curve3D' or 'GeometricCurveSet'. In case of 'GeometricCurveSet' only a single closed curve shall be contained in the set of IfcShapeRepresentation.Items.

The following additional constraints apply to the 'Profile' representation type:

  • Curve: being an IfcPolyline defining a rectangle.
  • Position: The curve shall lie in the xz plane of the object placement coordinate (the y coordinate values of the IfcCartesianPoint's shall be 0.).

Figure 6.1.3.16.H illustrates applying the door lining parameters to the door profile shape representation. The profile defines the outer boundary to which the door lining parameters relate as:

  • IfcDoorLiningProperties.LiningDepth starting at distance defined by LiningOffset going into the positive y direction.
  • IfcDoorLiningProperties.LiningThickness offset into the inner side of the rectangle.
  • IfcDoorLiningProperties.LiningOffset distance along the positive y direction to where the LiningDepth applies.
  • IfcDoorLiningProperties.ThresholdThickness starting at the bottom edge of the rectangle into the inner side of the rectangle
  • IfcDoorLiningProperties.ThresholdDepth starting at distance defined by LiningOffset going into the positive y direction.
  • IfcDoorLiningProperties.TransomOffset starting at the bottom edge of the rectangle (along local x axis) into the inner side of the rectangle, distance provided as percentage of overall height. Distance to the centre line of the transom.

Spatial Containment General

The IfcDoor, as any subtype of IfcBuiltElement, may participate alternatively in one of the two different containment relationships:

  • the Spatial Containment (defined here), or
  • the Element Composition.

The IfcDoor may also be connected to the IfcOpeningElement in which it is placed as a filler. In this case, the spatial containment relationship shall be provided, see Figure 6.1.3.16.I.

Containment
Figure 6.1.3.16.I — Door spatial containment

Even if the IfcDoor is a filling of an opening established by IfcRelFillsElement, it must also be contained in the spatial structure by IfcRelContainedInSpatialStructure.
