<p class=MsoNormal><span style='color:#1F497D'>That’s a good example. I’m
always amazed at the number of outside air dampers that are broken/disconnected,
have broken actuators, or crummy seals. A significant percentage of existing
buildings (and new ones for that matter!) have that problem. It would be great
if we had the time and budget to test all the systems to find problems like
this, but then we’re doing retrocommissioning on top of energy modeling.
And even then, our data is only as good as the meters and the people placing
them (is your mixed air temperature logger – with an error of 2-3% - just
a single logger ziptied right in the middle of the airstream, potentially
missing stratification?).<o:p></o:p></span></p>

Just some pent up frustration from being asked to do things that really don’t
make sense to me. I get the heebie-jeebies even thinking about calibrating a
model to an existing building, let alone to within 1-2%. I’m just hoping
someone will tell me that I’m being too academic and that these things
work themselves out in the real world. The DOE must have good reason to request
calibration within 1-2% other than a warm fuzzy feeling when they get results,
right?<o:p></o:p></span></p>

<p class=MsoNormal style='margin-left:.5in'><span style='color:#1F497D'>I
should make it clear that my initial 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 input side. (Although they were also
somewhat of a reaction to those 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></p>
<p class=MsoNormal style='margin-left:.5in'><span style='color:#1F497D'><o:p> </o:p></span></p>

<p class=MsoNormal style='margin-left:.5in'><span style='color:#1F497D'>“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

<p class=MsoNormal style='margin-left:.5in'><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal style='margin-left:.5in'><span style='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></p>
<p class=MsoNormal style='margin-left:.5in'><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal style='margin-left:.5in'><span style='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></p>

<p class=MsoNormal style='margin-left:1.0in'><span style='color:#1F497D'>While
I (and I am 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></p>

<p class=MsoNormal style='margin-left:1.0in'><span style='color:#1F497D'>I
haven’t done 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></p>

<p class=MsoNormal style='margin-left:1.0in'><span style='color:#1F497D'>It’s
fully rational to squirm and cringe when you have to make models that you know
will be mis-used and mis-understood, despite your best efforts. Fortunate
is the practicing energy modeler who gets to work for fully educated clients
and design teams all the time =).<o:p></o:p></span></p>

than drill David, I think it would be safe to assume those DOE requirements
exist to calibrate a model to a given degree to whatever historical records are

I’m wrong, I hope that work never crosses my desk!<o:p></o:p></span></p>

<p class=MsoNormal style='margin-left:1.0in'><span style='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></p>

<p class=MsoNormal style='margin-left:1.0in'><span style='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></p>

I always 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></p>
