Though I do not retract my statement with regards to energy plus and open
studio, I do agree that eQUEST is a great starting point.

I tend to use both, (eQUEST for preliminary, then Energy Plus, then
crossrefrence my Energy Plus model output with the eQUEST run) but started
with Energy Plus because I wanted to be able to model more then just
thermal and electrical energy systems such as, green roofs, solar electric,
solar thermal, vertical & horizontal wind turbines and have been recently
been modeling phase change materials. At first it was a bit intimidating,
but I got a feel for it pretty fast and now do not find the IDF editor to
be a difficult of an interface for input data, and google sketch up can be
used for the geometry and thermal zones.
The exciting thing about energy plus is the open source tools available
from NREL's Open studio project.
http://openstudio.nrel.gov/

And the new "Simergy" interface being realised by Laurence Berkley in April.
http://eetd.lbl.gov/bt/simergy/key.html

Bently havacomp has a new interface as well
http://www.bentley.com/en-US/Products/Hevacomp+Dynamic+Simulation/

And then there is design builder:
http://www.designbuilder.co.uk/content/view/29/44/


To me it makes more since to start with the latest and most powerful
software, that is being funded by the USDOE and is updated every 6 months.
eQUEST is great, but in the long run Energy Plus is a more valuable skill
set in my opinion. Also there are more features, and you can do interesting
things with the output...

A good example of something that is (from my understanding) not possible
with eQUEST my current research for phase change materials, is visualized
in this model of the generic phase change materiel from an example file, as
compared to a baseline building..( currently working on the new version
with bioPCM product data.).

To Robert I am very interested in dueling software! I also have a small
factory that I have yet to do the simulation for with drop box full of
details we could use in the duel ! Please let me know if you want to as it
sounds fun:)
