<p> The physical thickness of the wall is not counted in the zone
volume. It only impacts the thermal properties of the materials.
There is not 100% consensus in the building modeling community as
to which dimension (inside, outside, or middle) to choose. I
typically use the interior dimension for external walls and the
middle dimension for internal walls.</p>
<p>kind regards,</p>

<p class="MsoNormal">What I am trying to do is to trace the
internal geometry to build my house model and then apply
thickness of the wall.

<p class="MsoNormal">Generally, how does TRNBLD account for wall
thickness in the wall materials, does this just impact the
thermal properties of the material, or does this also impact
volume? If so, which direction will it impact the volume?
Inside, outside, or half-half?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is it possible to assign a wall thickness
specifically to go internally to ensure the internal volume
will be accurate if I trace external wall?<o:p></o:p></p>
<p class="MsoNormal">Or do I have to trace internal walls. The
issue with having to trace internal walls is that I then left
with gaps in between rooms.
