BLDG-SIM readers should be aware the PDF attached to the previous e-mail contains outdated and factually incorrect information for at least one of the software tools listed.


When a document like this is posted by a software vendor, it should only include data for that vendor’s own tool.  It should omit all other data since a software vendor cannot vouch for the accuracy of information about features and capabilities of competitor’s tools.

Latest version of this that’s been posted here a few times. What would be great is if developers of other tools like IES and TRNSYS would fill this out too.

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.

eQUEST is free and is DOE 2.2


It has CA defaults, but does that matter? 


Others are Trace, HAP.

What software do you suggest for Modeling Commercial buildings?


I live in Michigan work for a company doing energy audits from 5000-120000 square feet.


Energy Plus -over my head

equest-CA defaults

DOE 2.1 or DOE 2.2 ?


Would like a free option and one that I have to buy?

Thank you
