George, In my opinion, Both 1 or 2 shall be OK. For no 3, I am not really sure what your question is. However, you can assume your bay is your classroom. For no 4, it looks like LEED requires glare control for each window. You can check last bullet of option 1 and 3. In option 2, the sample of calculation shows the glare control provided in non-compliance area. Hope it will help.

Eddy, thanks for your reply. The idea is that when considering option 1, you require that 75% of the number of classrooms be compliant. However, option 2 seems to allow for a trade-off between classrooms. For example, I may have 40 non-compliant classrooms, by which 20 are underexposed to light (ex, Compliant area / Class area = 60%) and 20 are overexposed (ex, Compliant area / Class area = 130%). It is very possible that when adding the total compliant areas and dividing by the total classroom areas to get a value of 90% for example, by which this indicates "overall compliance". Many thanks,
