The reference guide (and the supplemental calculation spreadsheet) are very thin on explanation for earning exemplary performance. Of the four pathways, the 3rd has me confused. It states, "90% or more of regularly occupied spaces have access to unobstructed views located within the distance of 3 times the head height of the vision glazing."

Assuming a head height of 7', does this mean that occupants should have an unobstructed view from the window to 21' outside the building? Or does it mean that inside the room, you have to have unobstructed views 21' from the window back into the interior of the room?
