Hello,
Using this option, the LEED guidance requires to demonstrate through records of indoor light measurements that a minimum daylight illumination level of 25 fc has been achieved in at least 75% of all occupied areas.
Does anybody know if we also need to demonstrate that the illuminance levels do not exceed the maximum threshold of 500 fc such as in Option 1? It does not seem to be the case ...
Many thanks,

I agree, this does not seem to be the case. As a best practice, though, you'd want to check that this is the case, so that occupants don't suffer from glare and cover up the windows—negating your careful daylighting plan.
