<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Mr. Koran has made some good points on the
power of government funding to assure that EnergyPlus will eventually overtake
DOE2 and eQuest. But this doesn’t guarantee a better simulation
code. Doe2 has the backing of decades of usage and testing by millions of
experienced building simulation modelers worldwide. It has undergone
thousands of corrections and improvements during its lifetime, and has evolved to
the point that it has been widely accepted and used as the benchmark by which
other simulation codes are tested and proven.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>So my advice is let’s not be hasty
in writing off such a powerful legacy and jumping to something newer just
because it is receiving more funding at this point in time. Wasn’t DOE2
conceived and developed under federal (DOE) funding decades ago? Do we
need to start over with a new baby? We can all point out weaknesses in a
tool that we are all intimately familiar with, but have we spent enough time
and effort to look as carefully and critically at EnergyPlus? Not yet, because
we can’t until EnergyPlus (or any other newer software) has undergone as
much usage and scrutiny as DOE2 and its derivitives.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>No matter how much money is spent on a
newer code, I will personally put more faith and confidence in the more tried
and proven code. That kind of confidence can’t be bought; it can
only develop over a long time. When EnergyPlus has been proven to my
satisfaction to be better than DOE2, then I will be happy to switch.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Remember McIntosh computers and their
windows GUI? Has Microsoft created a better product? I don’t
think so, but we have been unhappily forced to switch because most other people
have, and it was all due to money and its power, not a better product. As
grass roots users of DOE2, let’s stick together and demand that
EnergyPlus be proven to our satisfaction to be at least as good as DOE2 before
we switch. After all, we pay our government to serve our needs, not to use
our money to dictate our choices.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=blue face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:blue'>I work mostly in the existing buildings
(non- or pre-"green) markets, but to the extent green buildings don't live
up to the promises is largely due to operaitons, not design. Many green
buildings are more complex, and since even more traditional buildings typically
have significantly sub-optimal operations, it is only logical that green
buildings will suffer at least as much when compared to expectations/simulation
results.</span></font><o:p></o:p></p>

<p class=MsoNormal><font size=2 color=blue face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:blue'>As far as Energy Plus and eQuest, I only
have experience with DOE-2 and eQuest. EnergyPlus should be superior
since it was built using the best of DOE-2 and BLAST. IIRC, it was moving
away from a transfer-function-based simulation to a heat balance-based
simulation. This should also help it to be superior in some
circumstances. DOE-2 derivative simulation tools are generally weak at
simulating suboptimal operations, and are very poor at simulating certain
controls improvements or retrocommissioning measures. I don't know how
much better EnergyPlus is in this regard.</span></font><o:p></o:p></p>

<p class=MsoNormal><font size=2 color=blue face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:blue'>At any rate, because of federal funding,
and that some (many/most?) federal projects and organizations will only allow
EnergyPlus, it seems certain that EnergyPlus is the future. My use of
DOE-2 dates back to before there were convenient interfaces and we dealt only
with BDL and user-defined functions, and we needed the stacks of documentation
to know what we were doing. I certainly believe that as more interfaces
for EnergyPlus are developed, more students come out of school with knowledge
of EnergyPlus, and more of us learn EnergyPlus, it will see greater and greater
use.</span></font><o:p></o:p></p>
