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!
