internal zone
A module defined by an interior division within a building or other structure, rather than by the whole object.
Internal zones are types of modules which are delineated by any kind of interior division of a building or structure.
The division identifies a portion of the interior. Its boundary separates that zone from other spaces within the structure.
A floor specifically describes an entire level. Internal zones can follow other interior divisions instead of representing the full horizontal level.
