LEED-CI 2009 EAc3 Case 1 Online form has options for sub-metering or central plant. Does the central plant mean that the tenant space is served by e.g. a dedicated chiller and no sub-metering is necessary, since you cannot fill out both?
If the whole facility is served by chillers piped to a common header at the central plant, the tenant space needs sub-metering on the chilled water branch serving the space. What is the correct way to fill out the form, sub-metering or central plant?

What is really being asked is whether the tenant space is served by a base building plant or by its own plant i.e. under the control of the tenant. If it's the former, submetering of the energy flows provided to the tenant space is required. If it's the latter, then monitoring of the tenant-controlled plant falls within the metering requirements.
