<p class="MsoNormal"><span lang="FR" style="font-size:8.0pt;font-family:"Verdana",sans-serif">Hi
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="FR" style="font-size:8.0pt;font-family:"Verdana",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:8.0pt;font-family:"Verdana",sans-serif">I use Type36 in Mode 2 (air flowrate computed internally, glazing transmittance as an input) to model a naturally vented Trombe wall.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:8.0pt;font-family:"Verdana",sans-serif">I use the multi-layer detailed window model from Type56 to compute the solar transmittance B3_QSTRNS/B3_QSEXT and U-value UWIN of the window (at each time step).<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:8.0pt;font-family:"Verdana",sans-serif">Looking at the source code of Type36 I cannot figure out how the model accounts for the inward-flowing portion of the solar radiation absorbed by the window. Therefore
I would rather provide SHGC (B3_QSTRNS+B3_QSHFPR)/B3_QSEXT instead of solar transmittance as an input to Type36.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:8.0pt;font-family:"Verdana",sans-serif">The drawback being all this inward-flowing portion considered as radiation absorbed by the massive wall. However the uncertainty (assuming all inward-flowing portion
is radiative) seems lower than totally neglecting the inward-flowing portion.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:8.0pt;font-family:"Verdana",sans-serif">Would somebody have a recommendation to share?<o:p></o:p></span></p>
