[Equest-users] What do reports report?

Keep in mind, LOADS reports LS- do not include outdoor air for ventilation -
that is added at the SYSTEM level.

Thanks.  I keep getting this advice to look at the detailed report
descriptions.  However, as I mentioned in my email, those descriptions do
not include the reports that I am referring to (or if they are listed, they
are out of order because I can't find them).

 

I'll check out the tutorial on DOE-2 again.  I have done this several times
and found no useful information, but I'll keep trying.

 

Charlie
