Instances of IdentifiedArea and Space enable additional classes beyond the CommonComponents to be associated. IdentifiedArea is an abstract class, see Figure 8, which can be realised in three implementable specializations: VehicularAccess, SupplementalFacility and SpecificArea. SubplaceElement and Space have a user defined code list related to occupancy level. This user defined code list enables a place to define codes for various occupancy levels and the definition of each occupancy level. As an example, a place or space may define occupancy levels using colour codes and define each colour code as follows: • • • • • •
User Defined Code 1: Green User Defined Code 1 Definition: Occupancy utilization is less than 80% of Supply User Defined Code 2: Yellow User Defined Code 2 Definition: Occupancy utilization is less than 85% of Supply User Defined Code 3: Red User Defined Code 3 Definition: Occupancy utilization is equal to or greater than 95% of Supply
