The elevator machine and controller are installed inside the elevator hoistway
, eliminating the need for a costly separate machine room in the building and freeing up premium space for rental or other use.
An alternative (and arguably a more promising) fire safety plan to pressurizing the elevator hoistway, which I suggest in the paper, is to pressurize the floors and force the smoke to stay in the shaft.
Pressurizing only the elevator hoistways may actually be counterproductive and endanger those trying to escape the fire by means of the stairwells.
Both the elevator tower and escalators are designed to follow the contours of the north side of the mountain, with the trees camouflaging the elevator hoistway
Instead of the familiar heavy steel ropes common in today's elevators, Gen2 uses flat, coated steel belts driven by a compact gearless machine mounted directly inside the elevator hoistway
instead of requiring a separate machine room above the shaft.
The code also allows for elevator hoistways
to be pressurized in lieu of providing enclosed elevator lobbies.
