Submetering requirement questions

[macintoshpie]

STD 211, 6.2.2.1.d requires the following for Historical Monthly Utility Data

A description of the submetering installed in the building (if present), including a listing of the systems metered, the frequency of data recording, and a description of the data acquisition system (fixed, portable, or integrated with the BAS), shall be provided.

BuildingSync's concept of submetering occurs at //auc:Utilities/auc:Utility/auc:MeteringConfiguration where the options are

• Direct metering
• Master meter without sub metering
• Master meter with sub metering
• Other
• Unknown

For our current schematron requirements, every auc:ResourceUse must have a one-to-one link with an auc:Utility (ie exactly one ResourceUse per Utility). We can add the requirements of defining an auc:MeteringConfiguration, but it wouldn't fully meet 211's specifications.

Some options might be to:

1. have users drop everything into something like auc:UtilityNotes
2. implement a new metering system. From Cory's notes:
   Characteristics:

• Link to a ResourceUse
• Be able to have sub-meters (or connect somehow)
• MeterID
• Sampling frequency
• Data acquisition system configuration

3. Don't require users to report this.

Note that the Normative Spreadsheet doesn't seem to fully meet these requirements either, they just require what's specified in auc:MeteringConfiguration which was mentioned above.

Submetering:

• Resource Use Meter ID: The ID of the meter as seen by the facility manager
• Resource Use Linking: Linking Resource Uses to other Resource Uses in a submetering context
