zone to model light/heat transfer into the space via the window/wall construction. A thorough investigation on this forum and a review of specific hourly reports could yield the answer you are looking for.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Adiabatic walls are interior surfaces which will not permit heat transfer, by definition.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">If you intend to add a window to an exterior wall, you should not be using an interior surface.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">If you intend to model a window in an interior partition, using an adiabatic surface may well hinder your efforts – better to switch an option which models
heat transfer.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">If your goal is to model the solar gains to a core space through a perimeter sunspace via interior windows, you should review the attached discussion from bldg-sim.
I understand this is possible with some care – but it requires careful review of the associated help resources to get all your ducks in a row. One “gotcha” is that you are required to use the “by glass code” definition approach for the associated exterior
windows.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">If your goal is to simply model the conductive heat transfer (not solar transfers) of those windows, you may consider defining an interior surface by construction
type (not adiabatic), and weight the U-values and areas of the windows & partition construction together for a net U-value –I did this extensively in the past, before realizing windows can be defined for interior surfaces.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Food for thought: I would not anticipate a correct model to exhibit a great change in energy consumptions if the two interior spaces in question are both conditioned
to similar/same setpoints. If the difference in temperatures are not great, changes in the partition conductive properties will not have a great effect as heat will not be inclined to move much to begin with.<o:p></o:p></span></p>
