font-family:Arial'>I am modeling a hotel in E-quest for a LEED project and am
wondering if I will need to provide a separate zone for each guest unit.
Each one will use an individual PTAC. Or if I can group several of them
together that share the same exposure and put them on one system that has
it’s capacities multiplied out to accommodate the number of PTACs.
It will save quite a bit of time if I can group them together, but I want to
make sure it will model correctly. Can anyone weigh in on this?<o:p></o:p></span></font></p>
