<p style='margin-left:.5in'>Dear all,<br>
<br>
When you are rotating the building through 4 different orientations, do you
change the glazing so that the glazing with the highest SHGC is always faces
north, or do you put the glazing with high SHGC on the original north facade,
and then rotate the building so that the high SHGC glazing faces the east,
south and west orientations in subsequent simulations?<br>
<br>
Yours faithfully,<br>
