I have a library that has a reading area with windows surrounding all sides but are separate by the interior wall, which makes the glazing non-continuous. The wall space between windows are approximately 6'3" or 8'6" apart. But the windows are still even dispersed throughout the walls of each reading area, so there are plently of multiple lines of sight 90 degrees apart. Can this still comply under View Type 1?

You will have to demonstrate that with diagrams. Maybe show on a representative section of the floor plan.
I tried the "it's obvious" argument and it did not work.

Edgar, in a similar scenario we earned the Credit by documenting the Views to GBCI with a combination of sketches of the Views Areas on floor plans, then some photographs of the Views from each Regularly Occupied Space. With both we considered the various lines of sight. For example, the closer to the wall section between windows someone would hypothetically work or study, they might not have a compliant View. The further from the wall, there might be multiple windows available to achieve a compliant View. Sometimes a Space had little or no Views Area, but when all the Views Areas were combined, they exceeded 75% of the total Regularly Occupied Space Area of the project.

The wall section between windows only have bookshelves facing them, all spaces where people would work or study is withing the central area of the reading space. So I feelt that would mean any occupant if they were sitting in one location around the central part of the reading area would have access to a compliant view, no?

Edgar, I also recall that we used the 2 View Types that would create the largest Views Area for the Space, and these differed by Space. Space 1 might have used View Type 2 & 3, while Space 2 used 2 & 4. View Type 1 was probably the least used for our project.

Edgar, regarding the bookshelves...if the fixture is permanently installed you can exclude this from total Regularly Occupied Space area, but any furniture can be moved such that in the future someone is studying anywhere in the open floor space. We imagined ourselves standing at all possible locations in the Space, then drew on a floor plan the combined Views Area where we have at least 2 View Types. If you have the v4 Reference Guide, Pages 759 and 765 have examples of this "standing in the room" perspective from several angles to document the aggregate Views Area.

Justin,
For comply with View Type 2, why is the 25 feet distance between outside object and the exterior glazing the minimum? Does it really matter if outside objects were less than 25 feet apart from the exterior glazing?
And for both View Type 2 and 3, is it just drawing a line of sight from the center of each window to determine that there are no interior obstructions? And if each space has enough line of sight from all the windows in the space showing two features from View Type 2 and everyone in the space has unobstructed views within three times the head height of the vision glazing, does that mean the entire floor area of that space complies with the credit under View Types 2 and 3?

Edgar
did you review the LEEDv4.1 criteria? Might be an easier path to compliance.

Just did, it would add more headaches since v4.1 requires the glazing to have VLT values above 40%. But thank you for your help.
