Dear Adrien,<br />
<br />
Please make sure that your "solar high noon" in your data matches the "solar high noon" coming out of Type16. This may be an issue with your start time - it could be off by an hour. Also, make sure you are NOT interpolating in Type9 for your radiation data.<br />
<br />
Best regards,<br />

<strong>Subject:</strong> [TRNSYS-users] Problem with Type16<br />
<br />
<!-- begin sanitized html --><font size="-1"><font face="Arial">Dear TRNSYS users,<br />
<br />
I try to use Type16 to obtain solar radiation on each surface (North, South, East, and West) of my building with IBH and IDH given and read by a simple data reader.<br />
The considered building is placed in Grenoble (lat : 45.12° - long 5.42°).<br />
I put those informations in Type16 parameters :<br />
Parameter5 (Latitude) = <b>45.12 degrees</b><br />
Parameter7 (Shift in Solar Time) = -15-(-5.42) = <b>-9.58 degrees<br />
</b>Parameter9 (Solar Time) = <b>1</b><br />
<br />
But beam radiation exceeds extraterrestrial radiation for 25 time-steps during the simulation. This problem occurs only for </font></font><font size="-1"><font face="Arial">East orientation</font></font><font size="-1"><font face="Arial"> (West orientation if parameter7 is positive) whatever the tilted surface mode (Parameter3).<br />
<br />
I have seen in TRNSYS users archive that other people have encountered problem in Type16 use, but I haven't found how to solve that issue.<br />
<br />
Any help will be appreciated<br />
<br />
Best regards<br />
<br />
