[BLDG-SIM] hornets nest?

[Mark Case]

I must confess I have no experience with TRNSYS. But I also don't seem to
see anywhere near as many references to it in the literature as I do for
DOE2.x. Is this a product of market penetration or a bias that DOE2.x is
used more for research and is therefor referenced in open publications more
often?

I'm only a computer science kind of person, with no real in-depth insight
in the underlying problems, but, in your opinion, where does the
TRNSYS multizone building model stand in this discussion - developped
by a private company, with its graphical interface (also developped by
a private company) and hundreds of users in private industry ?
Again, this is a naive question, please forgive me. (And yes, I am involved
in
TRNSYS developpment and biased).

I wonder if I could dare to send this to the list ... maybe not :-)

     Most of you are undoubtedly aware of the recent controversy over DOE2.2
PowerDoe and EnergyPlus. I know that many people on this list are actively
involved in one or more of these programs. I think this list is as good a
place as any to start a serious discussion about where things are going,
why, and how we (users of the tools) feel about these things. I'll start by
boldly stating that I don't believe EnergyPlus will provide a truly useful
(on-the-ground useful) tool for many years to come. The history of DOE and
the national labs in creating and releasing such software is not very good.
Are the labs and developers trying to create a product useable in a
competitive design consulting world? The last thing we need is another
arcane simulation package with no front end or post processor - been there,
done that. Perhaps new algorithyms and advanced coding are needed but
without the interface they won't help me at all. I'd rather use the `older'
ones and keep the ability to show designers what I'm doing. One more comment
and question - the DOE is spending our money to create new code and have
arguably abandoned the multi-million dollar investment in previous DOE2.x
developent. Is this the best use of taxpayer money? Come on everybody -
don't be afraid to weigh-in on this - let's hear your thoughts!
