I am diving back into Sefaira for the first time in a while, and the program still seems to be missing the ability to account for automatic daylight dimming in energy savings. Previously I had used an LPD reduction equivalent to emulate the savings automatic dimming would provide. Has anyone done a similar work-around?

I think we've all seen poly or fabric... Read more
