I am trying to calculate the requirements and was wondering about some technical details. This is for a library on a college university.
1. Does the window sill have to be between 30-90"? We have windows that start on the floor and go up to the ceiling, so the Window falls in the height requirement, but not the sill.
2. How much of the Window needs to be in view? If I'm standing in a aisle and look to the exterior glazing but only see a small amount of glazing (6"), does this count.
