Jeff,<br><br>Thank you for responding. I agree that it depends on the climate. <br><br>Design Builder has the option called 'flip' while making the double pane assembly. Hence I was not clear as to which surface is the coating on and what does flip actually mean?<br>

The "surface" depends on the climate. <br><br>Cooling dominated climates benefit from the low-E on the inside surface of the outside pane. <br><br>Heating dominated climates benefit from the low-E on the outside surface of the inside pane. <br>

<br></font><div><div></div><div class="h5">
Hello all,<br><br>I am trying to model several types of Low E glazing in Design Builder to understand the effect on the peak heating and cooling load. <br><br>While choosing different glazing, I could not understand which surface of the glazing has the Low E coating. <br>
<br>I would appreciate any inputs about this aspect.<br><br><br>Thanks,<br clear="all">Deepa Chandrashekaran, LEED AP<br>Master of Building Science 2010<br>University of Southern California<br><br>
