Riley,<br><br>If the over all U value and SC reported at the end of the LV-D report for each exposure match yours, I wouldn't worry about it. When you are looking at each window you are probably seeing some sort of adjustment for area.<br>

I set my frame widths to zero and defined my window glass type in “simplified” where I entered my total window U value in the “Glass Conductance” field. When I check my LV-D report it shows my windows having a lower U value than what I entered. I understand there are some variables at play here that are likely the cause (air film resistance and windspeed of rating (summer vs winter as shown in the topic help). I don’t understand what is going on here. </span></p>
<p class="MsoNormal"><span lang="EN-CA"> </span></p><p class="MsoNormal"><span lang="EN-CA">So, </span></p><p class="MsoNormal"><span lang="EN-CA"> </span></p><p class="MsoNormal"><span lang="EN-CA">Can someone shed some light on why my LV-D window U values don’t match my “Glass Conductance” value in these circumstances?</span></p>
