Building

class compas_ifc.entities.Building(entity, model)

Bases: SpatialElement

Class representing an IFC building.

Notes

The order of spatial structure elements being included in the concept for builing projects are from high to low level: IfcProject, IfcSite, IfcBuilding, IfcBuildingStorey, and IfcSpace with IfcSite, IfcBuildingStorey and IfcSpace being optional levels. Therefore an spatial structure element can only be part of an element at the same or higher level [1].

This means the minimum spatial structure of a project is:

• IfcProject

  • IfcBuilding

    • IfcBuildingElement

Therefore, all building elements found in a model can be accessed through the Building class.

model = Model(filepath)
for project in model.projects:
    if project.sites:
        for site in project.sites:
            for building in site.buildings:
                for element in building.elements:
                    # ...
    else:
        for building in project.buildings:
            for element in building.elements:
                # ...

Attributes:

addressstr

The compiled address of the building.

building_storeysList[BuildingStorey]

The building_storeys contained in the building. If the building_storeys are not properly nested, they can be found at the top level of an IFC model.

spacesList[Space]

The spaces contained in the building.

building_elementsList[BuildingElement]

The building elements contained in the building.
