[Bldg-sim] (no subject)

All:

I am modeling a two story office building that is 20,000 square feet.  The actual building employs a packaged rooftop unit with VAV's and electric reheat.  If I read ASHRAE 90.1 correctly, I am to use System 4 for the baseline modeling.  This is in stark contrast to what is actually installed.  

If I am understanding this correctly, do I take from this that Packaged Single Zone Heat Pumps are preferred in this application?  

Thanks,

Mike Porter
