Hi,
i have two questions about this credit:
First we have a pretty big campus project with seven individual buildings. If i understand this credit correctly then it would mean that with a master site we have to calculate all seven buildings as if they were one big building? Becasue otherwise we would have some buildings that reach the benchmark and some that dont.
Second question: for another local certification we were requiered to simulate the daylight of the building but different to LEEd we were requiered to proff that a daylight factor (calculated from a certain point of the rooms) does not fall below a certain benchmark throughout the year. My question now, if this benchmark is above or equal to the lowest LEED benchmark could we use this calculation for our certification?

As for daylight, the buildings would have to be simulated individual under a master site unless they are identical.
As for your second question, daylight factor is no longer an acceptable metric used by LEED to determine daylight performance. You will need to either use point time calcs, Spatial Daylight Autonomy, the prescriptive, or measurements. Daylight factor is a very old metric that would get you into the ball park. If you are using a computer simulation tool to determine daylight factor it would be no problem to switch metrics and rerun the simulation. If you are calculation daylight factor by hand, there is no method to my knowledge of comparing daylight factor to any other metric currently used by LEED.
