Tenant submetering

The purpose of this credit is to install the infrastructure needed to install individual meters for each tenant's space. If the tenants pay for their own energy use they tend to pay more attention to it. Centrally monitored means that the metering data comes to a single location and can be read from that location. I suppose it could be a wireless system, sending a wireless signal from the sub-meter to the central monitor. A subtraction as described will not enable individual tenants to be sub-metered. This credit does not require you to sub-meter by energy end use and calibrate the energy model, that is EAc5.1.

I agree that the corrective action related to energy savings part of the credit requirement language is confusing to me too. Perhaps the corrective action is intended to be taken at the tenant level but since there is no prediction of energy savings. Maybe this is explained in the Reference Guide. I would think that if each tenant space could be separately metered by the power company for each fuel type then you could make the case that it would qualify. They certainly have the means for central monitoring! You would probably need to show that the electrical system in the facility has been designed to allow for such separate meters. In my experience the utility will not install a whole bunch of meters serving individual spaces so the owner submeters the building but pays the utility for the whole thing.
