Hello,
TRNSYS returns be plenty of these errors in listing result file :
winlib reader: incorrect selectivity of visual+solar transmission caused a negative value for nonvisual Transmission Tra_ang_nonvis = -0.045 for Window-ID 4202 at an angle of 30 ° Tra_ang_nonvis is set to 0 for this angle
I use the library
C:\Program Files\Trnsys16\Building\Lib\Basic\W4-lib.dat
Actually, I would need a window with a u-value of 0.1 kJ/h/m²/K , and because there are not such window, I use the smallest value : 0.4.
But for each of the windows with this value, I have the same error.
Can you help me? At least to know why does this message appears?
Note: the issue is the same if I try in
American\W4-lib.dat, German\W4-lib.dat...
Have a nice day!
