color=#0000ff size=2>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.</FONT></SPAN></DIV>

color=#0000ff size=2>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.</FONT></SPAN></DIV>

<DIV dir=ltr align=left><SPAN class=453114802-13042009><FONT face=Arial
color=#0000ff size=2>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.</FONT></SPAN></DIV>

<P dir=ltr><SPAN lang=en-us><FONT face=Calibri>A few of you ask me to post the
result from my very unscientific survey.</FONT></SPAN></P>
<P dir=ltr><SPAN lang=en-us><FONT face=Calibri>The list is split
50%, 50% in their opinion that EnergyPlus will become a natural transition to
eQuest.</FONT></SPAN></P>
<P dir=ltr><SPAN lang=en-us><FONT face=Calibri>The basic sentiment is that
eQuest is recognized to be less capable, but faster and easier to
us</FONT></SPAN><SPAN lang=en-us><FONT face=Calibri>e.</FONT></SPAN><SPAN

<P dir=ltr><SPAN lang=en-us><FONT face=Calibri>Someone asked me why Bentley
cares. We believe that there’s a hole in the U.S. energy analysis/simulation
market. We believe, as this survey indicates, that the tools available to
U.S. designers seem to fall into two camps</FONT></SPAN><SPAN lang=en-us><FONT
face=Calibri>. Tools that are</FONT></SPAN><SPAN lang=en-us> <FONT
face=Calibri>easy-to-use, but inaccurate/incomplete</FONT></SPAN><SPAN
lang=en-us><FONT face=Calibri>. Or, tools that are</FONT></SPAN><SPAN
lang=en-us><FONT face=Calibri> precise, but difficult to use and
slow. </FONT></SPAN><SPAN lang=en-us> </SPAN></P>
