Patent ID: 7734572

Claim:
A method of event management in a building control system having multiple building control subsystems each including a plurality of devices, the building control system comprising a zone controller operating as a local area controller, the method comprising the zone controller: collecting data from the subsystems; storing the collected data; analyzing the stored data to determine patterns of behavior in a building and to generate customized reports based on sequences of related events; grouping software objects from the building control system into subsets, the grouping triggered by a predetermined criterion or a logically tested set of occurrences; indexing the subsets based on at least one of: relevance, relationship, or causal relationship to form indexed subsets; assigning a name, label, identification number, address, or equivalent for the indexed subsets to form a grouped object sequence; and storing the grouped object sequence, wherein the building control system comprises a plurality of point objects, the grouping of software objects comprising associating each point object with an area object, a system object, a controller object, and a subsystem object, the point objects able to undergo logical association with more than one area object, more than one system object, more than one controller object, and more than one subsystem object.
