Abstract:
This paper presents a discussion of the features of
protected elevator systems that can provide
safe and reliable operation both for fire service access
and for occupant egress during fires.
These features include water tolerant components,
fail-safe power, lobbies on each floor
designed as areas of refuge, smoke protection, occupant
communications, and real time
monitoring of the elevator position and operating
conditions from the fire command center.
Egress simulations are used to quantify the improvements
in efficiency that can be realized by
incorporating elevators into the access and egress
procedures for tall buildings. Finally,
operational procedures will be discussed for the most
appropriate use of vertically zoned
elevator systems that are found in most tall buildings.
These procedures would form the basis
for the elevator control software that needs to be
developed for such systems.
