For a core & shell project in which the developer does not have control over interior (tenant) build-out, why does the LEED Online form require (or is automatically populated with) EPA Target Finder values (Target Finder Score, CO2 emissions, CO2 emissions reductions)??
Is GBI/USGBC assuming the building will have a portion of 'base building' items/equipment that is metered separately from the tenants? Are the Target Finder numbers supposed to reflect these 'base building' items only or are the "Total Annual...Energy" numbers generated within the Target Finder program supposed to reflect the ENTIRE building (tenants included)??
Thanks.

The target finder numbers should be based on the energy model, which would reflect the entire building, including tenant spaces.

If following the prescriptive option allowed under EAp2, an energy model will not (most likely) be put together.
And how would an energy model deal with vacant, unleased tenant spaces, where interior design and loads are not known??

Future tenant spaces get modeled as occupied spaces. You need to assume a likely use, pretty easy if it is an office building. Any systems that are not yet installed (lighting, for example) get modeled as minimally code compliant.
