Please help with this scenario:
Core and Shell project with 8 tenants (light manufacturing).
Goal of achieving EAc5.1 and EAc5.2.
The developer will meter total energy use of the Core areas and also submeter HVAC and lighting loads AT THE PANEL using in-panel meters.
The M&V plan will give direction and forms for collecting energy use data as well as documenting changes in occupancy, schedules, and equipment.
Local weather data will be gathered and recorded manually from a local airport database. This information will be provided to the Energy Simulation Provider for input into the Baseline and Calibrated simulations, as appropriate.
Tenant spaces will be wired at the panel to facilitate submetering of HVAC, process and lighting loads with IN-PANEL meters (which are accommodated but not provided). Plug loads will derived by subtracting measured energy from total energy use from the utility-provided meter.
Forms for recording energy use data will be provided as well as guidance for corrective measures if energy use exceeds targets (as established by the tenant).
In my mind these conditions satisfy the intent of the M&V credits without the added expense of a BMS. I don't understand the requirement of a "Centrally monitored electronic metering network in the base building design." Has anyone been successful in using this type of strategy?
Thank you.

You do not need a BMS for either credit. There are other ways to get the data.
Keep in mind that the data you need for 5.1 is not the same data you need for 5.2. Submetering by energy end use can be used for 5.1 while submetering by fuel type is required for 5.2. To earn both credits requires two different M&V plans.

To add onto this, the condenser water, hot water and air systems are capped at the individual tenant spaces, and the electrical loads are seperately monitored.
The tenants are encouraged to submeter at the connections, and pay per calculated per loads. Does this credit require that each tenant submeters at the connections or can the tenant opt for the base building cost method? Since we are only installing electrical meters and not the fuel meters, can we achieve this credit by promoting but not requiring the use of submetering? Would a penalty for non-sub metered tenants assist?

It is my understanding that the infrastructure must be in place that would enable the tenants to submeter each fuel type but they are not required to do so under CS.
