Is this measuring that 90% of spaces simply have access to views with a view factor of 3? For instance you will get credit if you are able to walk to a position in the room that allows you to have a view factor above 3. Am I understanding this correctly? Thanks for any help!

In simplest terms, yes. Any location within a space that provides an occupant a view factor of 3 or greater count. Exactly how this is done is not really spelled out anywhere.
I would break a space down into a 3'x3' gird. Basically the space occupied by a person. if the center of that space offers a view factor, it counts.
When it comes to documenting the exemplary performance for this credit, i would recommend waiting till construction is complete and you can take pictures. Especially if you are going to have some real small view angles where a reviewer could question the legitimacy of the area having a claimed factor.
Hope this helps.

Just want to clear up what looks like might be some miscommunication. Dennis, there is no walking involved. The occupant has to be able to see the special view as they are seated at their desk. They may have to turn their head or chair around, but if they have to get up and walk to the view it doesn't count. Is this how you understand it, Todd?

Yes, its only from a stationary position, work station, regularly occupied space. So a worker having to get up and move into the aisle would not be acceptable.
So if you did not have a view factor of 3 from your workstation, that area is not compliant. You should only consider the areas considered regularly occupied. So circulation areas, which are not used in the regular credit, would also not be used in the exemplary performance.
Dennis's question was a little confusing, so that is why i noted to break the space into a grid and analyze each space in the grid.

What constitutes an occupant a view factor of 3?
