allows the elevator to generate energy
on the way down. In the past, there was
no means to capture and regenerate that
downward power into electrical energy.
But that has changed. These traction elevators have improved controls, hardware and other systems.
While traction elevators are getting
smart, a new type of elevator has entered the market - and it's even smarter.
Called "destination dispatch," this elevator calculates how to get passengers to
their destinations faster and tells them
which elevator to use.
New destination dispatch control
technology allows elevators to reduce a
building's overall energy usage by reducing the number of stops a group of ele-
vators make. In theory, this technology
will reduce the total number of elevators
required in a building.
"Destination dispatch is a more efficient way of getting people to their destination quicker," Seifried says. "It's gaining popularity, but it can come at a price."
When using a typical elevator, passengers must first call it by pressing an
up or down button. Once inside, they
select their desired floors. Destination
dispatch elevators are different. Instead of pushing a button to go up or
down, passengers first select the floor
they want while still outside of the elevator. The passengers are then directed to an elevator that will take them to
their destination with the fewest number of stops.
"The real payoff is that [the building's
owners] may have enough efficiency so
that they could have one less elevator,"
Seifried says. "Besides the energy reduction, it saves them space, which they can
then rent out."
Destination dispatch control elevators
are designed for mid to high-rise buildings. Such a system wouldn't make sense
for a building that is less than 10 stories.
As one of the largest independent elevator door equipment manufacturers,
GAL often introduces new and innovative products to the industry. It recently introduced its new line of linear door
operators, called NextDOOR.
"This smart equipment is our latest elevator door operator," Seifried says. "It
is an intelligent door operator which
