<p class="" style="margin-bottom:0.0001pt"><span style="font-size:12pt"><font color="#274e13">Thank you for your
response. You are right; I check with the architects, they are using “Kawneer
1600”. I input the data in Frameplus Online and it gives me U-0.48 for the glass
and U-0.20 for the total spandrel with 2” insulation. </font></span></p>
<p class="" style="margin-bottom:0.0001pt"><span style="font-size:12pt"><font color="#274e13">Assuming the spandrel
system as steel wall, per Nick’s suggestion (Thanks Nick), per ASHRAE Table
A3.2, assembly U-factor for this wall is 0.113. Unfortunately, both options
indicate U-factors that are greater than the U-factor of the baseline model
(U-0.064 for zone 4A) and reduce the total energy savings for the project. Am I
right in selecting U-factors?</font></span></p>

If so you could use Frameplus Online which models insulation within and behind spandrel panels, you just need to figure out the thermal break thickness - it has 3 thermal break options. </div><div style="text-align:initial;color:rgb(31,73,125);font-size:initial;width:100%;font-family:Calibri,'Slate Pro',sans-serif">
