<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="FR" style="font-size:8.0pt;font-family:"Verdana","sans-serif"">Looking at the documentation p. 5-111 (Window data used by the Type 56) and 5-167 (Heat Flux between Window Panes) I do not understand what is the exact use of the
overall glass transmission coefficient in Trnbuild. Indeed it seems that the overall transmission is rather computed based on the physical properties of glass and gap layers. If the value from the Window file is indeed used could you please confirm me the
actual ambient conditions: have they been changed to be closer to the standardized ones?
