I am trying to calculate the depth of shadings for each hour of the year to achieve 300 to 500 lux illuminance. The problem i have encountered is that each time i run the daylight analysis for the same situation (same time, percentage of window and depth and number of shadings), it gives a different level of light with a huge difference (more than 100 lux). i have attached the file and two pictures from the same situation and time.
Any help would be greatly appreciated!
