Does anyone have any experience with tenant sub-metering and compliance with this credit? The sub-meters will be arranged to monitor the lighting and plug load energy use of each suite throughout the building. By the letter of the law it seems that EAc3.2/EAc3.3 requires that all sub-metering is broken down by energy use categories and not by end users. It is my feeling however that tenant sub-metering would still meet the credit intent. It allows building tenants to be billed directly for their energy use and, in turn will promote responsible energy management. Finally, tenant sub-metering of lighting and plug loads together is allowable in LEED-CI EAc3.
Before I send through a CIR I thought I'd see if anyone could pass through some insight.

I feel that your approach sounds acceptable, and I even gave similar guidance to someone above. I think that language about the end user is to disuade people from submitting just because they meter individual tenant spaces (that would be the end-user bit).
But you'll need to verify that lighting and plug loads meet the minimum percent of total energy use. And depending on the building type, those systems are often low consumers.
CIRs are always a safe bet, even with their price tag.
