I'm seeking information on others' experiences with the application of
ASHRAE 90.1-2013 8.4.3 Electrical Energy Monitoring. If you have
existing monitoring systems and would be willing to share your
experiences :
1) Are you using one metering approach or a variety of
solutions (i.e. branch circuit level metering or energy meters at
distribution equipment designated for HVAC, lighting, and receptacles)?
2) Is the system performing as expected?
3) Are there any lessons learned?
4) Was a variance to the mandatory requirement ever pursued?
