I would have defined a single construction separating the airnode
above from the airnode below (instead of defining two BOUNDARY
surfaces). To get the surface temperature of the ceiling side of the
construction, select the airnode that contains the ceiling when you
are in the TRNBuild output manager. Change to "surface outputs" and
select the TSI ntype (ntype17). <br>
Best,<br>

<p class="MsoNormal">I am modeling a single floor of multi-story
building with an in-ceiling radiant system. I have defined an
active surface has a carpet on the “floor” side and exposed
concrete on the “ceiling” side.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I naturally defined the ceiling of the
airnode as an active surface, but also defined the floor as an
active surface as well to account for the effects of the
underlying level’s radiant ceiling. Both the ceiling and the
floor of the airnode are defined as boundary surfaces with a
fixed temperature on the other side. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Here’s my problem – I am interested in
recording the airnode’s CEILING temperature (at the exposed
concrete surface) – but within TRNBUILD the ceiling and floor
both have identical surface areas and I cannot tell which is
which! The only differentiable marker I observe is the surface
type. Is there any simple way to find which of the two
surfaces is the Ceiling in this case?<o:p></o:p></p>
