<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Thanks for getting back to me! I knew about the surface numbers, but sadly those didn’t help, even at the airnode window level. In the airnode window, when the ceiling and floor are both boundary constructions
with the same other-side condition, they appear to be identical in every way - barring surface number - so there’s nothing extra to specify which number is the ceiling!<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">I solved the problem by exporting the BUI back into TRNSYS3D, and assigning the ceilings as boundary constructions with T_UP as the other-side temp and the floors with T_DOWN as the other-side temp. Upon reimporting

Got it. I thought for some reason that your two surfaces were back-to-back and made up a ceiling of one zone and the floor of the one above, not a floor and a ceiling in the same airnode.<br>
<br>
In any case, if you look in the airnode window and click on each of your "walls" you'll notice that there is a number listed in blue to the right of the "geosurf" field. This is a surface number indicator. When you then go into the output manager, and start
selecting your surfaces, you'll notice those same numbers listed.<br>
Best,<br>

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).
