Dear equest experts,
I have following issue.
Accorting ASHRAE 90.1.2010 table G3.1.1A my baseline building is following:

System 8-VAV with PFP Boxes

More specific according table G3.1.1B. The system is
VAV with Parallel rooftop VAV with reheat, Fan control VAV, Cooling type
Chilled Water, Heating type electric resistance.

1) To model this system in equest I have choosen PIU system in equest (see
following screenshot)

2) In the heating table I have completed as following

Do you find these choice correct?
Do you have any suggestions?

3) How shall I treat the humidity control in the baseline building ? Is it
the same with proposed building?

Thank you very much.
The answers I get from this forum are always helpful.

Best regards

Hi Konstantina,

To model the System type-8 you are required to have the system as VAV but
not power induction unit as per me.

The system that you are required to take in the baseline case is Variable
Air Volume in the system type which is as follows:

In the heating tab you are correct as per seen.
The thing that System type-8 has is that it has both heating as well reheat
that is provided as zone heat source or zone reheat.

In the Humidity Control you shall have to have the control as per the space
likewise the proposed case or as per reference guide norms. A typical
example is given as follows:

Hope this might clear your understanding.
