A portion of one or more floors in a building or an outside facility that is defined by an area contained within a bounding line or lines on the floor or site plan and provides a setting for an Activity or activities.

Typically a Space will be quite granular, contiguous and contained within a single floor (or elevation) – for example a single meeting room, a restaurant booth, or a car parking space. Analysis will then consider sets of spaces. However, sometimes it is helpful to define Space in other ways – for example an elevator shaft that is contiguous but spans many floors, an upper floor in a single building that splits into two disconnected towers in the upper sections and so is not contiguous, or a number of disparate buildings that collectively form an urban university campus (being neither contiguous nor contained within a single floor).

Space is measured based on its Area, Capacity or Resource Count.
