[Bldg-sim] Chilled Water Loop / Bldg Modeling

[Sparks, Jason]

I've been tasked with finding a software package that can model our chilled water system.   We have a district plant that distributes chilled water to many buildings on our campus.  My specific task is to model the chilled water system of one specific building, then those results will determine if we continue looking for a different software package, or proceed to model the other buildings.  Pretty much they want a computer model of the buildings chilled water system that can predict the chilled water flow requirements for each AHU & the total building as a function of the buildings chilled water supply temperature, outside air conditions, and air handling unit flow rates.

I'm looking at eQuest & EnergyPlus (as they're the only free options I've found so far to play with), and I'd really like some opinions/suggestions on how to proceed.

Thanks

Jason
