<P align=left><SPAN class=784422912-10022009><FONT face=Arial size=2>I have done
several energy models over the last few years using Trane Trace. I have
heard others (typically from those who don't have experience with energy
modeling) say "it only takes a day" to create an energy model and get
results. </FONT></SPAN></P>
<P align=left><SPAN class=784422912-10022009><FONT face=Arial size=2>I am trying
to get a better understanding of how long it takes others to complete an energy
model. I realize there are many factors involved and length of time can
vary drastically given the complexity of the project.</FONT></SPAN></P>
<P align=left><SPAN class=784422912-10022009><FONT face=Arial size=2>For an xxx

What phase are you starting the energy model - SD, DD, CD?</FONT></SPAN></P>
<P align=left><SPAN class=784422912-10022009><FONT face=Arial size=2>2.
What information are you starting with - load results from another program,
rules of thumb for system sizing, etc?</FONT></SPAN></P>
<P align=left><SPAN class=784422912-10022009><FONT face=Arial size=2>3.
What program are you using?</FONT></SPAN></P>
<P align=left><SPAN class=784422912-10022009><FONT face=Arial size=2>4.
How long does it take to build the proposed model?</FONT></SPAN></P>

How long does it take to build the baseline model (per ASHRAE 90.1-2004,
Appendix G)?</FONT></SPAN></P>
<P align=left><SPAN class=784422912-10022009><FONT face=Arial size=2>6.
How long does it take to calculate the results from the energy simulation
program?</FONT></SPAN></P>
<P align=left><SPAN class=784422912-10022009><FONT face=Arial size=2>7. If
you have started a projected in the SD phase, how detailed is the input
information you use? How do the results compare to the energy model
developed in CD - within 10%?</FONT></SPAN></P>
<P align=left><SPAN class=784422912-10022009><FONT face=Arial size=2>Any
information you can provide would be helpful.</FONT></SPAN></P>
