It appears that there are numerous questions about the depth of the compliance area, but I don't believe there's a question regarding the width of the compliance area. I may be overthinking the compliance method, but is it simply just the width of the window or will LEED allow an additional amount of feet on either side of the window to use for compliance? If LEED allows additional feet on either side of the window to use for the compliant area, please let me know if this is referenced in the handbook and where.
For example, I have a classroom wall that's 20' and the window in the wall is only 10' wide. I can only then consider approx. half of the classroom area to be in compliant with view type 3, right?

Laura, I think you are correct that it is just the window (or other glazing) that can count here.

Read the entire section on how they determined a view factor. its view that takes up 1/4 of a persons field of view. It explains what angles are used for a field of view. The further away from the window wall, the greater the amount of glass needed.
