[Bldg-sim] Parallel Units for LEED

[Jorge Torres-Coto]

You only model them as they are supposed to run (one at a time or both at
the same time). 

 

You mention they run in parallel, so I assume that the capacity of both may
be required at peak load.  If they operated lead/lag, then you would only
model one (or half AHU capacity per floor).

Subject: [Bldg-sim] Parallel Units for LEED

 

Hello All,

 

I am trying to model a three floor office building for LEED V3. The first
and second floor are served by two chilled water air handlers, both
manifolded and running in parallel.

Does LEED require to model both the units because the schedules and drawings
show two units.

For baseline, I know ASHRAE G3.1.1 states I have to have seperate HVAC
system for each floor, as I have system 5.

Thanks and Best Regards,
