<DIV><FONT face=Arial size=2>Pat Bailey @ Geopraxis (<A
href="mailto:pbailey@geopraxis.com">pbailey@geopraxis.com</A>) recently
provided us with an actual weather file in DOE2 format that we are using for a
similar calibration exercise. </FONT><FONT face=Arial size=2>Most (90%+)
of the DOE-2 stuff we do is with new construction, so we just go ahead and start
with the typical weather file. But in the case of retrofit, where you are
trying to calibrate to existing usage, I think the actual weather is the way to
go. Will let you know in a few weeks how it turns out
;-)</FONT></DIV>
<DIV><FONT face=Arial size=2> </FONT></DIV>
<DIV><FONT face=Arial size=2>I suppose you could also do the weather normalizing
separately, by comparing DOE output kW vs. metered kW in different wetbulb or
drybulb bins at different times of the year.</FONT></DIV><FONT face=Arial

<DIV><FONT face=Arial size=2>Hi bldg-sims: </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>After using DOE modeling tools intermittently now
for many years I am now using eQuest and one of its cousins in earnest.
After reading the manuals a couple of things still are not totally
evident.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I would like to synchronize the eQuest modeled
behavior to the actual utility bills for a given calendar year (so I know I
modeled it properly), then apply the 30 year average data to tell me how the
building should perform going forwards in a baseline mode and after EEMs are
applied.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Am I correct that the only way to do that is to
take real weather data from say 2002, use some of the weather utility
applications to create a suitable packed format for the DOE-2 engine, run
that, make sure it is calibrated properly, then switch the weather data to
30-year data and re-run it. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Do most of you seasoned modelers keep two sets of
all your weather data laying around, DOE-2 packed actual yearly data plus the
30 year formats? Or isn't it worth it?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Also, can I input actual bill histories into
eQuest to compare modeled versus actual bills?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any suggestions would greatly be
appreciated.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks,</FONT></DIV>
