I would generally take the “delete the wall” approach 9 times out of 10
without a second thought. In the event you do feel the mass of the
common wall has a significant thermal lag effect you don’t want to eliminate
in your model, I’d advise still just deleting the wall and bumping up the
value for the furniture mass (located under the contents tab for the space in
question).<o:p></o:p></SPAN></P>

<P class=MsoNormal>You will have to define the common wall as an "adiabatic"
interior partition -- no heat transfer and no solar load. In the wizard
you can do this by clicking on the wall (in Shell screen 2 of the DD wizard)
and then selecting adiabatic. In detailed mode you can also delete a
exterior wall and then create an interior partition of type adiabatic.
You could also simply delete the common wall -- this also has no solar and no
conduction load. The only thing this does is decreases the room's
thermal mass slightly (not of significance likely). <BR><BR>There is no
way to create and interior partition and to force the temperature of the
adjacent space -- you would have to create the "next to" zone if you really
want to model heat transfer between new and existing. Unless the
occupancies are significantly different, the impact of conduction across that
wall is likely negligible.<BR><BR>Good luck.<BR><BR>BF<BR><BR>On 11/10/2010

<P class=MsoNormal>As further clarification,<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></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.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></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.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></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.<o:p></o:p></P>

<P class=MsoPlainText>If you've gone through the wizard your interior and
exterior walls should be in tehir correct places.<o:p></o:p></P>
<P class=MsoPlainText><o:p> </o:p></P>
<P class=MsoPlainText>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.<o:p></o:p></P>
<P class=MsoPlainText><o:p> </o:p></P>
<P class=MsoPlainText>Exterior walls define heat transfer between the space
and the outside.<o:p></o:p></P>
<P class=MsoPlainText><o:p> </o:p></P>
<P class=MsoPlainText>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).<o:p></o:p></P>
<P class=MsoPlainText><o:p> </o:p></P>
<P class=MsoPlainText>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.<o:p></o:p></P>
<P class=MsoPlainText><o:p> </o:p></P>
<P class=MsoPlainText>I would model it as an interior wall - especially if
there is a space on the other side.<o:p></o:p></P>

<P class=MsoPlainText>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?<o:p></o:p></P>
