[BLDG-SIM] Appendix -G & Purchased Heat

[Vikram Sami]

I'm a little confused about this passage (read below)

G3.1.1.1 Purchased Heat. For systems using purchased
hot water or steam, hot water or steam costs shall be based on
actual utility rates, and on-site boilers shall not be modeled in
the baseline building design

Does this mean that if my building is using purchased steam, I can take
no credit for the efficiency provided by a central plant? As far as I
remember, for purchased chilled water, the procedure for the base
building is to model a system from table G3.1.1A & B and use the chilled
water rate for the proposed building. Is this not the same for purchased
heat?
