public building backup power

all public buildings nationwide should be required to have a minimal

to run emergency lights, get elevators to ground level, and stuff
like that.
people stuck in elevators is really dumb in this day and age
Elevators in our condo were update last year with a feature that uses
gravity to automatically return them to the bottom floor if the power
fails. No emergency power required.
Yeah, but how fast does it go down?
