Common Questions

1
What are the 15 CIE sky types?

The CIE (Commission Internationale de l'Eclairage) defines 15 sky models representing different levels of cloudiness and solar concentration, based on ISO 15469/CIE S 011.

2
Why use CIE sky models instead of simple overcast?

CIE models provide a more accurate representation of real-world light distribution, which is critical for precision daylighting and glare analysis.
