<div dir="ltr">Hi Joe<div style>I also suspected that the under cooled hours may caused by window angular property, but the loads reports you indicated show there's no big swing on the solar heat gain for 15 degree azimuth compared to 10 and 20 degrees azimuth, however i found there's a great difference in peak system cooling load in SS-J reports, the peak load for 15 azimuth is about a half of the load for 10,20 azimuth, so I guess the DOE program may uncorrectly calculated the system peak load？but when i used your weather file for simulation the unmatch hours disappeared!</div>

The only difference between the different azimuths is the solar
radiation. <br>
I think you should compare the summary loads report (LS-E by
space, or LS-F for the whole building) for the different
orientations and see how much the solar heat gains, especially
through the windows, change. If you really want to get into it,
you can also print out hourly reports for the solar heat gains,
heating and cooling loads for the ground floor zones. You can
also switch weather files and see what happens. I will send you
by e-mail a different weather file for Wuhan that I've created.<br>
Good luck.<br>

<div>I was doing orientation study on my office module i can
not figure out why i got 26% OF HOURS OUTSIDE OF
THROTTLING RANGE in BEPU report when i set the azimuth at
15 degrees for ground floor, the system worked in
throttling range when azimuth at 10 or 20 degrees! the
weather file i used is CTYW Wuhan (china). </div>
