Hi everyone,

I am working in a very large building, which has many different space usage
types.

The HVAC Project consists in a lot of AHUs, constant volume, fan coil units
and active chilled beams.

The issue is that there are almost 1500 spaces distributed in the different
systems.

I am a little disoriented because I started modeling my Project Building
with each one of the AHUs without discriminating each space, but this AHUs
attend different space usage types, for instance, one of them is for the
?Pharmacy?, and it attends circulation, office spaces and storage.

According to the number of floors, building area and heating source, my
Baseline HVAC system will be System 7, Variable air volume with reheat. So I
will assign one VAV AHU for each floor. And then, how will I assign each VAV
zone?, do I have to model all the 1500 spaces or will it be enough to model
a VAV box for each AHU as defined in the Project Building?,

I will really appreciate your comments on this,

Thank you,

Paula
