1. A building management system for monitoring equipment status, the building management system comprising a processing circuit configured to:
generate a rule based on one or more sub-rules and one or more equipment points, wherein the rule is a relationship between the one or more sub-rules and the one or more equipment points and indicates whether the piece of building equipment is experiencing a fault, wherein generating the rule comprises automatically altering the rule responsive to alteration of one of the one or more sub-rules;
determine, by the processing circuit and according to the rule being satisfied, one or more faults that are associated with a space of a building based on building data of the space;
determine, for each of the one or more faults and by the processing circuit, which particular piece of building equipment of a plurality of pieces of building equipment that service the space is associated with the respective fault based on the rule being satisfied;
generate one or more diagnostics based on a diagnostic equation that uses the rule to determine the diagnostics for one or more faults in the piece of building equipment;
identify a root cause of the one or more faults based on data from each of the one or more faults, wherein the root cause is a diagnostic of the one or more diagnostics that is associated with a first fault of the one or more faults;
determine instructions for resolving the first fault based on the identified root cause;
select task details comprising the instructions; and
generate, on a user interface, a work order based on the identified root cause by populating the work order with the selected task details including the instructions for resolving the first fault.
