Hi!

I am doing studies about coupling daylight and thermal simulations.

Therefore the internal gains due to lighting are very important and I am trying to understand how exactly the dimming factor in the intgain file (between 0 and 1) is calculated when a ballast factor is included.

There must be sort of a simple characteristic (linear?) curve for the lighting system depending on the node illumination value, target illumination and ballast loss factor.

I would be glad about some help!
