Daylight in Corridors
Fifty percent of the square footage of a corridor may be excluded from the definition of floor area if a window with a clear, non-tinted, glazed area of at least 20 square feet is provided in such corridor, provided that such window:
(a) shall be directly visible from at least 50 percent of the corridor or from the vertical circulation core. This standard shall be achieved when a visually unobstructed straight line can be drawn between such corridor, elevator or stairwell, and the window; and
(b) is facing a street, yard or court that meets the applicable regulations set forth in Article II, Chapter 3.
