Hi Karen-

To Add to the correct answer given by Grant

No, you cannot have two lighting schedules on the same room. But that
doesn't mean that you can't do what you intend to do.

Two options I've used:

1) Find the peak watts/square foot for all lights, and use a lighting
schedule (the schedule just multiplies the peak watts/square foot by a
percent - so you can essentially "merge" two schedules into one and account
for the hourly lighting). However, this may not be possible if you are
concerned about heat to the plenum

2) Create custom misc. load called something like  "Process lighting" in
the library/template editor. You can set up the percentage of the lights
that goes to the plenum and set everything but the ballast factor, which
isn't necessary in such a case. You can have multiple receptacle loads per
room and thus add a 2nd lighting schedule as well as have plug loads.

Hope that helps, but let me know as I can guess at a few questions that
might come up, but I don't wish to be long-winded as Grant probably
answered the question for you.
