EnErgy ManagEMEnt The New Age Of Energy Metering Maximizing the benefits of real-time sub-metering. By Ed Pantzar T hrough advancements in technology the traditional submeter has become obsolete. No longer is energy data privy to only the facility manager, who jots down monthly totals from the depths of a utility room.

Now energy meters allow each of these entities to actively utilize information for their own benefit, and they do. Apartment residents can now view energy consumption of their own apartment through a dedicated user portal. Using a graphical display feature makes simple acts such as turning off all lights a source of instant gratification.

(Solid red = total load, shaded red = total energy consumed from grid, gold = lighting circuit, black = server closet, rightmost column = instantaneous power bar.) customized to the facility's specific needs.

Advanced sub-metering systems come outfitted with various forms of communication protocols to further a facility's control. The ability to communicate via BACnet ® (Building Automation Control Network) is Second-by-second graph with sub-loads.
