1. A method comprising:

  • associating, by at least one data processor, a plurality of controllers with one of a plurality of building zones based on a floor plan of a building, each of the plurality of controllers connected to one or more loads;

    associating, by the at least one data processor, each of the plurality of controllers with an IP address such that each controller has a unique IP address, wherein the IP address comprises a network address and a host identifier, and wherein a first network address for each of one or more controllers in a first building zone is the same and is different from at least one other network addresses of at least one controller not in the first building zone;

    associating the first building zone with at least first and second subzones;

    associating at least two controllers with the first subzone, and associating at least one other controller with the second subzone; and

    transmitting over an IP network, by the at least one data processor, a control message using a broadcast IP address having the first network address, the control message including a first subzone parameter for causing one or more operational parameters of the one or more loads connected to each of the at least two controllers in the first building zone and in the first subzone to change based on the first subzone parameter, and the control message not causing one or more operational parameters of one or more loads connected to the at least one other controller in the first building zone and not in the first subzone to change.
