Wwe are working on several CS projects that have good daylight illumination levels. Nevertheless, there are some spaces that go over the 500 fc limit.
In the LEED form for IEQ8.1 it's obvious that if you don't install glare control you can't get the credit but that doesn't make sense to me. If I have 100,000 sqft of offices and I go over the 500fc limit in only a couple of spaces totaling 1,000 sqft I can't get the credit? Or should I simply deduct that area from the area that complies?
Thanks.

Hi Jana,
I believe you can deduct the area that does not comply. In addition, I would suggest to take a look your building design, High illuminance level usually means that your room will receive direct sunlight.
Regarding glare control, you may provide luminance/glare study and try to prove that the glare will not be a problem in your space. There are many glare control strategies, outside common strategies mentioned in LEED reference.
In this credit, LEED actually wants to address 2 issues in daylight design such as illuminance level issue and luminance issue. The glare requirement is to address luminance issue, while your simulation/calculation is to address illuminance level issue.
Hope it helps...
