Looks like what eQUEST is doing is turning exterior walls into adiabatic interior walls. Because even in detailed mode, only interior walls have this option. This is what the wizard mode exterior wall defined as adiabatic looks like behind the curtain<div>

<p class="MsoNormal"><span style="font-size:13.5pt">You have the right idea. Depending on the
building of course, but I try to lump the part you aren't concerned about onto
one AHU, and default everything in that portion. You are only concerned
about the intersecting wall and it's condition. Add your other AHU's and
zoning for the portion you want to work on. With the one extra AHU is
makes it relatively easy to back out its numbers from the building analysis and
you are left with what you want.<br>

<p class="MsoNormal">I’m
looking for recommendations of how to model just one section of a building in
eQUEST. Three sides are exterior walls, while the fourth is connected to
the rest of the building, and therefore next to a conditioned space.
Would the best method be to just use two separate shells (1 – the building
“wing” I’m analyzing, 2 – the rest of the building), although I’m only
concerned with one of them? Is there a better way to do this? I’m
hoping someone can point me in the right direction. </p>

<p class="MsoNormal">As further clarification,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">If you delete any wall/ceiling/roof, you (1) remove both a
source of heat storage (thermal mass) while also (2) removing any heat transfer
across that surface. As a caution: Losing the first effect can be a
lot more significant that you might assume, depending on what you’re
looking into.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">If you instead change any interior surface type to
“adiabatic” (in the same wizard/detailed places you might select
“air” or “internal”), you will remove heat transfer
while retaining the thermal mass of the construction. This may be the
best route when trying to study a perimeter classroom in isolation, for
example.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Quirky thing is, you can’t change an exterior surface
type (roof/floor/wall) to adiabatic, so as Vikram is saying you have to first
create an interior surface, copying across the geometrical properties (polygon,
vertices, azimuth…), then delete the exterior surface. Make sure to
define and assign an interior surface construction (layers) if the Wizards
haven’t already set this up for you.</p>

<p> </p>
<p>Reba,</p>
<p> </p>
<p>If you've gone through the wizard your interior and
exterior walls should be in tehir correct places.</p>
<p> </p>
<p>Interioir walls should separate two spaces, and will
define heat transfer between those two spaces. You normally have to define
which space is on the other side.</p>
<p> </p>
<p>Exterior walls define heat transfer between the space and
the outside.</p>
<p> </p>
<p>If you are in detailed mode, you can delete one and
create the other as a child component to the space. When you say large air
space - is that the air cavity in the wall? I'm not sure what resistance eQUEST
attributes to the larger air gaps, but in reality air cavities over a certain
size (I think 1 inch is probably the upper threshold) increase their convective
heat transfer and the cavity resistance should go down (not up).</p>
<p> </p>
<p>If your just looking to make it adiabatic, I think you
should be fine with just deleting the wall. You will lose the thermal mass of
the wall material though.</p>
<p> </p>
<p>I would model it as an interior wall - especially if
there is a space on the other side.</p>

<p>Subject: [Equest-users] make exterior wall an interior
wall</p>
<p> </p>
<p>I’m running a simulation on just a portion of a
building. eQuest sees all walls of the polygon as exterior walls.
In reality some walls are interior and will not have heat transfer. Is
there any way to make eQuest see those walls as interior walls?
I’ve thought of defining those walls with super insulation and a large
air space so heat transfer is negligible. Anyone tried that?</p>
