unique type of surface in that they have zero mass but a relatively low
conductivity (by default, approximately the same as a single layer of 3/8”

emphasize is that models ultimately serve a purpose, and that it’s
important at the beginning of any project to identify that endgame. Sometimes
it’s getting LEED points, sometimes it’s advising new or retrofit
design for existing envelopes, HVAC, and/or lighting, sometimes it’s
because there’s academics who simply want a model they can pick up after

<p class=MsoNormal> Is it possible to simulate an open door or a open
window in a face with outdoors boundary conditions? (only calculating
heat loss or gains to the enviroment). Example: If I apply a "infrared

<p class=MsoNormal>Hi all,<br>
<br>
<br>
In DOE-2 program, "air wall" is a type of interior
walls without thermal mass effect, only for thermal resistance(0.9
hr-ft2-F/btu) between zones. I think other similar simulation
programs have also the same function. <br>

You mention the use of "Real walls or <b><u>air walls</u></b>"
between zones in your post. I feel this raises a question on this list that
I've already enquired on this list. I apologise for raising the issue once

"virtual partitions".</span><o:p></o:p></p>

<p class=MsoNormal><span style='font-family:"Arial","sans-serif";color:black'>Rohini,</span><span
style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:black'><br>
<br>
</span><span style='font-family:"Arial","sans-serif";color:black'>Zoning a
building is still an art form. There are very few papers that have looked into
this with any rigor. </span><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";
color:black'><br>
<br>
</span><span style='font-family:"Arial","sans-serif";color:black'>In one thesis
we did on the Zachry building, which was the basis for the Predictor Shootout I
and II, we looked at 1, 2, 5 and actual zoning on the building. What we saw was
that, in general, the centroid of the "cloud" of data points remained
about the same. However, the scatter in the cloud became more pronounced
at we added more zones.</span><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";
color:black'><br>
<br>
</span><span style='font-family:"Arial","sans-serif";color:black'>So, if all
the zones in the floor are being operated the same, I'd use 1, 2 or 5 zones per
floor, depending on the functions of what's going on in each zone. Real walls
or air walls between the zones usually get the job done.</span><span
style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:black'><br>
<br>
</span><span style='font-family:"Arial","sans-serif";color:black'>The quickest
way to get the light and receptacle loads on a real building is using
"blink" tests, which can be done on a Saturday, with walkie talkies,
and a data logger on the whole-building electric feed, possibly some sub feeds.
I first heard of this test from Todd Taylor at PNNL. We've used it to help
resolved motor loads, lighting loads, receptacles, etc. Seems to work pretty
well. </span><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";
color:black'><br>
<br>
</span><span style='font-family:"Arial","sans-serif";color:black'>There are
also several ways to get the plug loads, including: by proxy, by
weather-day-type profiles, by daily readings, and a method that uses an energy
balance. The proxy methods can use square proxies for for the occupancy based
on OLF/ELF ratios, the weather-day-type method was something that I heard about
from Don Hadley at PNNL, later adopted by Bou Saada on the Forrestal building
and daycare center. The daily readings are just that, read the main meter by
eye, daily, especially during weather independent times. The energy balance
method is documented in papers by Claridge et al. at the ESL.</span><span
style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:black'><br>
<br>
</span><span style='font-family:"Arial","sans-serif";color:black'>There is also
some encouraging work being done by Abushakra and Reddy on ASHRAE RP 1404, now
in progress and scheduled for completion later this year. This is based on
previous work by Abushakra for his Ph.D. thesis.</span><span style='font-size:
