I'm modeling an apartment building that has toilet and bathroom exhaust and no mechanical supply for the apartments. Make-up air comes from trickle vents.
I have been thinking about the best way to do this, that is whether:
- I should assign this to a zonal exhaust fan (EXHAUST-FLOW), or
- I should specify the CFM exhausted as an outdoor air flow (OUTSIDE-AIR-FLOW).
I think the OUTSIDE-AIR-FLOW would be the least problematic if I only had to deal with the baseline, but in my proposed building I only have baseboards for heating, so this wouldn't work.
First, am I correct in the above statements?
Second, if I do specify an exhaust fan in the following way: FAN-CONTROL = CONSTANT-VOLUME EXHAUST-FLOW = 50 EXHAUST-FAN-SCH = "Fraction Always 1 Yr" EXHAUST-SOURCE = INFILTRATION
- Will eQuest actually take into account that 50 CFM of outside air should be added (through infiltration) as a load?
- Will eQuest also take that into account for the sizing of my zonal equipment?
- Finally, will it interact in any way with the infiltration defined under Internal Loads for the Space?
