Hi guys, i was wondering if anyone has any advice on a simulation i am trying to do: i basically need to find out if trees placed in front of mt building facade affect the daylight that enters the building. I need to show how much light autonomy we have in the room and how the trees affect that. I am unsure which type of simulation/ node i should run first of all ( should i focus on radiation, or sunlight hours nodes? and how exactly can i show with clear data results that the trees i place at specific locations next to my building facade affect it and how much? pretty please help
