I am a bit confused about the daylight simulation. We have carried out simulations for every occupied space in the building at 09:00 AM and 15:00 PM. We take the percentage of areas that are between 25-500 fc for each space. Naturally, the percentages differ for the same space at different times. Which percentage are we supposed to use? Minimum or average? Is there any clarification from USGBC about this?
