1. A building management system comprising:
one or more memory devices configured to store instructions thereon that, when executed by one or more processors, cause the one or more processors to:
receive one or more of variable air volume unit (VAV) data or air handling unit (AHU) data from one or more data sources;
determine that one or more VAVs qualify as a suspect VAV in response to one or more conditions being satisfied by at least one of (i) the VAV data or (ii) the VAV data and the AHU data;
classify the suspect VAV as a first type of suspect VAV in response to a first set of the one or more conditions being satisfied;
classify the suspect VAV as a second type of suspect VAV in response to a second set of the one or more conditions being satisfied;
in response to the suspect VAV being classified as the first type of suspect VAV, remove a portion of the VAV data associated with the suspect VAV from a calculation of a duct static pressure setpoint (DPT-SP) for an AHU and operate building equipment to affect an airflow provided to one or more building zones using an adjusted value of the DPT-SP after removing the portion of the VAV data associated with the suspect VAV from the calculation of the DPT-SP; and
in response to the suspect VAV being classified as the second type of suspect VAV, increase or decrease the value of the DPT-SP and operate the building equipment to affect the airflow provided to the one or more building zones using the increased or decreased value of the DPT-SP.
