<p class="MsoNormal"><span style="color:#1F497D">Dear all,<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 am currently modeling a double skin façade with a double glazing outside and a single glazing inside:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Office – single glazing – cavity – double glazing – outside<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 would like to know the solar gains inside the office. Nevertheless I didn’t find any output giving the amount of solar radiation inside the office (so behind the two glazings): indeed I can get the solar radiation
inside the cavity (behind the double glazing) but inside the office results of the output are zero.<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">It might be that the output consider only external windows?<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">Then I tried to calculate the solar gains based on solar radiation inside the cavity and on g-value of the single pane, the latter calculated by TRNSYS (NType51). I got the same troubles, because the g-values
calculated from TRNSYS for the single pane are equal to zero again.<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">Then I wonder about the way TRNSYS is taking into account the solar radiation in this specific case. Is my single glazing well considered and then is the calculation right?<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 am using TRNSYS 17 and I calculate the beam radiation with the detailed model, based on my geometrical data (modeled in SketchUp).<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 thank you in advance for your answers…
