Mixed sky definition

Post by nishant.kuchekar » Mon Jul 08, 2013 7:29 am

Hello all,

I want to ask a basic question. What does "mixed sky" actually mean?
Is it an average/mean of clear sky and overcast sky, or does it have its own assumptions?

Thank you

Dear nishant,

The included sky types in DIALux (clear, overcast, mixed sky) are based on the CIE110-1994 »Spatial Distribution of Daylight - Luminance Distribution of Various Reference Skies«.
If you need more information we recommend you to take a short look into the manual.

The CIE S 011 E:2003 ,,Spatial Distribution of Daylight – CIE Standard General Sky” which is the latest version are 16 sky types declared.

The clear sky equates the sky12= »CIE Standard Clear Sky, low luminance turbidity« from CIE S 011 E:2003.
Furthermore the overcast sky in DIALux equates the skytyp16= »traditional overcast Sky« from CIE S 011 E:2003.
The mixed sky in DIALux has no consent regarding the CIE S 011 E:2003.

I hope, that my suggestions suites your expectations.
