Modeling Level of Detail Definitions

The Modeling Level of Detail (MLOD) is similar in concept to the Model View Definitions (MVD) defined by IFC. MLODs define a subset of the overall BuildingSync schema necessary for a specific use case or workflow.

Level definitions are in alignment with the ASHRAE Standard 211 levels as defined below:

MLOD Use Case Alignment to Std 211 Std 211 Section
Level 000 Audit Preliminary Analysis Section 5.2.3
Level 100 Audit Level 1 Section 6.1
Level 200 Audit Level 2 Section 6.2
Level 300 Audit Level 3 Section 6.3
Level 400 Audit Not Applicable Not Applicable
Level 500 Audit Not Applicable Not Applicable

HVAC System Examples

Where the System Type specified below does not exactly match the enumeration in the BSync XML file, check the mapping defined by map_primary_hvac_system_type_to_cbecs_system_type. Additionally, see the examples/HVACSystems directory for a tutorial and example files.
