I've asked this question before, but never really got a good answer, so
I'm trying again in case anyone has new info.
Has anyone successfully submitted a LEED v3 Core and Shell Energy Model?
Under v2.0, there was a LEED-CS EAc1 calculator explained here:

It was a great way to subtract out energy loads that the Owner/Developer
did not have control over.
However, under the new v3 Green Building Reference guide (includes NC,
CS, etc), they appear to have gotten rid of the sliding Developer/Tenant
scale, and now award just a different quantity of points for CS vs NC.
It certainly looks that way, and the v3 online template couldn't
possibly be more confusing to me, so I can't really tell by looking at
that.
Is this true? If so, it's a shame, because if you have a Core and Shell
project where there is an Owner requirement to provide a mechanical
system capable of supporting 5 Watts / sq ft tenant plug loads, you can
no longer back out the plug loads as an energy consumer "not controlled
by the Owner/Developer". I could reduce the plug load density to help
shrink the numerator/denominator, but that's not really an accurate
thing to do in a C&S project, since the Developer HAS to provide cooling
for 5 W / sq ft because of things like SFOs, specific tenant
requirements, etc. C&S projects are a completely different animal than
an NC project where you already know and can guarantee tenant loads.
That sucks. Can anyone confirm?
