questions weren’t meant to drill David. I’m genuinely interested if
the DOE projects required an extremely high level of technical accuracy on the

requirements.) We have this discussion in our office every so often, and
I’m usually somewhat on my own, but I’m still not convinced.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color="#1f497d" face=Calibri><span
style='font-size:11.0pt;color:#1F497D'>So let me ask it this way. Let’s
say you’ve got a model, and it’s coming in about 6% low (both
heating and electric), but to the best of your knowledge everything is set up
properly. You’ve got to start making some educated guesses to close the
gap. Do you assume the boiler needs a tuning (drop your efficiency a few
percent) and the AHU coils need to be cleaned (bump up your static)? Or do you
bump up your infiltration slightly (because it’s probably not a very
tight building). Or did some maintenance guy came along and switched on both
the boiler pump manually on when he got a cold complaint, and no one returned
them to auto? Or maybe you have data from a few years with abnormally warm
summers and cold winters. I could go on practically ad nauseum. There’s
just so many things that can be wrong with an existing building, as all of you
probably know.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color="#1f497d" face=Calibri><span
style='font-size:11.0pt;color:#1F497D'>Whatever you choose, that guess you make
may interact (or lack an interaction) with some measures you’re
predicting. So, predicatively, what makes a 1-2% off model better than a 5-6%
off model unless you really spend the time and find out whether your inputs are
accurate? <o:p></o:p></span></font></p>

sure many others) have books to write regarding my thoughts on the topic, I
think I might suggest a simple step back: The concept of <u>predictively</u>
modeling to within a few percentage points of accuracy is ridiculous.
There are simply way to many things that could not be known.
HOWEVER: The concept of building a model for an existing building,
whose modeled energy consumption/costs fall within a 1-2% of historical utility
records, is entirely feasible – and a reasonable requirement if the goal
is to generate a model for predictive purposes. How often such predictive
models’ accuracy is misinterpreted is something I get depressed to think
about.<o:p></o:p></span></font></p>

the DOE-modeling work that’s being referenced with such requirements, but
I have done work for educational clients (physics/building science departments)
who wish to get these models set up for ongoing study/tweaking purposes.
The exercise is challenging, and as close as energy modeling gets to
“fun,” when you can rest at ease knowing the client is fully on
board with what the model is and isn’t. <o:p></o:p></span></font></p>

face=Calibri><span style='font-size:11.0pt;color:#1F497D'>How much effort was
put into minimizing the error of your inputs to justify that level of accuracy
in your output? For example, did you convert real weather data for the two
years and use an average of the simulations? Were you modeling small buildings
so you could get a fairly reasonable infiltration rate empirically? Were
occupancy schedules trended, and for how long? Were all the systems and
controls working correctly, with all sensors calibrated regularly? <o:p></o:p></span></font></p>

<p class=MsoNormal style='margin-left:.5in'><font size=2 color="#1f497d"
face=Calibri><span style='font-size:11.0pt;color:#1F497D'>1 to 2% seems to me
to be fairly unreasonable. Unless you do an amazing job verifying your inputs,
in my opinion that level of precision doesn’t get you a better model. If
you set everything up as best you can and it comes in there, great! But a
correctly set up model can be off by over 2% because of a couple “El
Nino” years, a facilities guy locking a humidity high limit to 50% for a
summer, or any number of operational factors. On the other side of it,
we’ve tried to match a simple DOE2.2 model to a DOE2.1e model with
limited success (I don’t think we got within 3%, although we didn’t
spend too much time with it). Who knows what the difference would be with E+.<o:p></o:p></span></font></p>

squirm when I’m asked to do existing building models, and it may be
irrational. Heck, if the DOE is asking for 1-2%, I probably am being
irrational. But it seems to me that the error from assumptions could easily swing
a model 1-2% (what would a 30% error on your infiltration do to an otherwise
correct building?). What are other people’s thoughts? <o:p></o:p></span></font></p>
