Wallie,

I've never tried this method, but I came across this thread yesterday when I
was perusing the archives for other data...let us know if this approach is
successful for your project.

I've done this only once, but here's how I went about it:

You model the chilled beam system as an induction unit (assuming it s a
passive chilled beam). You will need to model it's OA from a DOAS
system. Since the chilled beam system itself does not use fan energy you
will need to set your kW/cfm at zero. The fan energy gets captured at
the air handler. Now with the lab I was modeling the chilled beam was
running on 100% OA, so this was a valid approach.

If the chilled beam air handler has recirculation air (return air),
this might not be a valid approach.

This is a great help. Thank you Mr. Pasha and Mr. Vikram. I'll apply all this and keep you posted in case problem arise and i can't figure it out.
