[TRNSYS-users] Problem with Type16

[Adrien JEZEQUEL - ITF <a.jezequel@itf.biz>]

Dear TRNSYS users,

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.
The considered building is placed in Grenoble (lat : 45.12° - long 5.42°).
I put those informations in Type16 parameters :
    Parameter5 (Latitude) = 45.12 degrees
    Parameter7 (Shift in Solar Time) = -15-(-5.42) = -9.58 degrees
    Parameter9 (Solar Time) = 1

But beam radiation exceeds extraterrestrial radiation for 25 time-steps during the simulation. This problem occurs only for East orientation (West orientation if parameter7 is positive) whatever the tilted surface mode (Parameter3).

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.

Any help will be appreciated

Best regards
