Glossary page split (verified 2026-07-10)
On the live IFC-SG glossary, this component's content is split across two pages under the parent Space component:
| Page | GUID | Holds |
|---|---|---|
| Space Usage | 156265b6-a7ab-44dc-aa0e-8fa2a9e8dcee |
The value catalogues: list of Space Names and Occupancy Types per building typology (the big lookup tables) |
| Space Usage (Others) | d0a72875-f11a-4a53-9a1b-bfd84b9ea775 |
The 31-parameter property table (IfcSpace/SPACE) — verified to match this component's parameters.json exactly, 31/31, zero diffs |
The "Others" page intro: "In addition to Occupancy Type and Space Name parameters and values listed earlier, some space components may require additional parameters listed below." — i.e. the other 29 are conditional, applied per space type.
⚑ Required pair (parent Space page)
The parent Space component states: "each space only require 2 'IfcSpace' properties to address their usage requirements: 1) SpaceName 2) Occupancy Type".
SpaceName⚑ — values from the Space Usage catalogue pageOccupancyType⚑ — SCDF occupancy type, values from the same catalogue
Both are input_limited — pull accepted values from the Space Usage page's lookup
tables, not free text.
Other input-limited parameters
These accept values from a defined list in the COP source table (not part of the global structural enums); see examples in parameters.json:
