[Bldg-sim] ASHRAE 90.1 Baseline LPD and occupancy sensor credit

All,

This question pertains to a LEED energy model per the ASHRAE 90.1 Appendix
G. Occupancy sensors are required in spaces such as conference rooms and
employee lunch/break rooms per Section 9.4.1.2 and no lighting power
density credit can be taken for their use in the proposed design model.

My question is, do the baseline maximum LPDs prescribed by ASHRAE, say 1.3
W/sf for conference rooms, already account for the power 10 or 15%
adjustment for occupancy sensor use or does the credit have to be manually
applied on top of the 1.3 W/sf in the Baseline model?

Thank you,
Ramana Koti.
