  14. 1/6/2017 Requirements Identifying major energy end uses is the first step in choosing what to meter. Often, in large commercial or industrial buildings, end uses are classified as systems composed of discrete pieces of equipment that can be Install advanced energy metering for the following: metered together. For example, � � Chilled water system: chillers, chilled water pumps all whole-building energy sources used by the building; and � Condenser water system: cooling tower, condenser water pumps any individual energy end uses that represent 10% or more of the total annual � � Hot water system (natural gas): boilers consumption of the building. � Hot water system (electricity): hot water pumps � Air-handling system: supply fan, return fan, damper motors The advanced energy metering must have the following characteristics. � Meters must be permanently installed, record at intervals of one hour or less , and Examples of typical end uses for a commercial office building that may require advanced metering include the following: transmit data to a remote location. � Receptacle equipment � Electricity meters must record both consumption and demand. Whole-building � Interior lighting electricity meters should record the power factor, if appropriate. � Space heating � � Space cooling The data collection system must use a local area network, building automation system, � Fans wireless network, or comparable communication infrastructure. � Pumps The system must be capable of storing all meter data for at least 36 months. � � Heat rejection � The data must be remotely accessible. � Exterior lighting All meters in the system must be capable of reporting hourly, daily, monthly, and � � Service water heating annual energy use.
