<p>Htet Ye Wynn,</p>
<p> Take a look at the windows in your building and make sure that
the frame u-values are all reasonable. If you have used internally
calculated convection coefficients for your windows, you might
want to switch that off and use constant values just to see if you
can pinpoint the cause of the problem.</p>
<p>kind regards,</p>
