Here is one final post from the Fulton Center in New York City. The day I visited I was somewhat surprised at how old-school the design of this atrium is despite the modern appearance. Office buildings prior to World War 2 often didn't have artificial light so they relied upon natural light to get their work done. Rents diminished quickly the farther a room was to a window so developers and architects often designed office buildings with massive light wells. That meant sacrificing rent-able square footage but the remaining space could be rented out at a higher rate. Incidentally the reason having a "corner office" was considered so valuable is because it typically had twice the amount of light which in theory resulted in productivity gains for the higher paid managers.
The main atrium of Fulton seems to take its cue from that bygone era. The interior space was almost entirely lit by the giant sky-reflector net. As a result the space felt airy enough but on this overcast day the space seemed dark. The gray coloring didn't help much in this regard.
As the tenant spaces begin to fill in it will be interesting to see how the interior lighting of the space changes.
