FlucsDL CIE overcast sky model
Posted: Tue Jan 21, 2014 3:12 pm
Hello,
When I have to calculate DF, I choose CIE overcast sky model, but how can I know which zenith luminance corresponds to my location?
Due to Wikipedia, standart CIE overcast sky corresponds to 11921 Lux
http://en.wikipedia.org/wiki/Daylight_factor
Is IESVE calculating outdoor luminance for each location or taking standart 11921 lux?
Due to manual for FlucsDL, page 29, the CIE Standart Overcast Sky is 10k (10 000 lux). Why not 11921 lux?
Looking forward to your answer.
