Our company is in charge of validating an office building compliance with credit IEQc8.2 - Views, under LEED2009 V3. 

The building floorplate is shaped as a rectangle that repeats itself on 16 floors, with no fixed furniture, and curtain-wall facades on every side.

How are we supposed to draw lines of sight? Do we have to indicate a 90degrees view cone for any arbitrary point? Do we have to trace these cones of sight starting from the façade going towards the inside of the floorplate or should we do it all the way around (meaning from critical points towards the outside)?

Thank you!
