[Bldg-sim] question

[Chris Yates]

Mike,

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.

TAS now has an A90.1 tool. It looks easy to use but as I haven't used it 
I can't speak authoritativley.

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.

I hope that this helps.

Chris
