While exporting the ecotect model to radiance to carry out daylight simulation, saveral sky conditions are highlighted in option bar, which are as follows.
1 - sunny sky with sun
2 - sunny sky without sun
3 - intermediate no sun
4 - itermediate with sky
5 - uniform sky
6 - overcast sky......
I don't understand the 2nd, 3rd and 4th codition. lets take an example of 2nd condition "sunny sky without sun". However, as far as "sunny sky" is concened, it means there is sun in sky than obviously direct solar penetration would occur and in this case the daylight levels inaside the building would be more. So what does "without sun" mean associated with "sunny sky"?
Though I have simulated a model while keeping both sky conditions (1 & 2) to see the difference in the result, but haven't found any difference .
Please explain the sky conditions mentioned above..........
Does it really say sunny sky without sun?? As far as I am know, there are five types of sky condition.
c)intermediate sky (mid-season)
d)cloudy sky (winter)
