It depends on what you are trying to accomplish. If you need LEED or
Ashrae 90.1 analysis then DOE, Equest and E+ seem to be the only ones
that handle the waterside hvac in the prescribed manner. They are all
free.<br>
<br>
TAS now has an A90.1 tool. It looks easy to use but as I haven't used
it I can't speak authoritativley.<br>
<br>
I heard of users modelling for A90.1 with alternative tools whilst
handling the waterside with seperate calculations. Of these tools IES
is probably the easiest and fastest simulating. If you do not require
code compliance I would probably recommend IES as the commercial option
for large buildings.<br>
<br>
I hope that this helps.<br>
