I am working with the lighting control group component, and had a question about the appropriate input for the lighting power. Is this intended to be the summed power for all of the fixtures in a group, or just for one fixture. Judging by the rest of the inputs I am assuming the latter, but I wanted to double check to make sure I was not assuming incorrectly.
Hi @thomsong, This is an input for Daysim and Daysim assumes an ideal lighting system for modeling and not the actual light fixtures:
In the first category [which is all that is available!] DAYSIM assumes an ‘ideal lighting system’. In this case the electric lighting system itself is actually not being modeled but instead the daylight in the space is modeled. For this simpler option the only parameter required to describe the lighting system for each zone is the installed lighting power and the target illuminance. It is assumed that the lighting system will deliver this target illuminance when fully switched on.

Excellent, thanks for the clarification, Mostapha.
