Ready To Switch Gears?
Make the smart move toward lower elevator energy costs.
By Nathan Lee
t certainly isn’t news to building
owners in Hawaii that electricity
costs are the highest in the country.
But what you may not know is how
you can save energy and operational
costs with your elevators.
Oftentimes modernizing your
elevators and escalator can make the
single largest impact on reducing
energy consumption. Depending on
your building’s needs, this can mean
anything from something as big
as changing gears to something as
simple as changing your oil—literally.
Geared to Gearless
If you’re ready for a big change,
a geared to gearless modernization
is the way to go. It reduces power
consumption by eliminating the
use of a motor generator. Elevator
companies can help you customize a
modernization plan that works best
for your building.
To minimize disruption to your
tenants or customers, existing geared
machines, controllers and motor
generators can be removed one
elevator at a time. The old equipment
is replaced with micro-processor
controls with advanced dispatching,
an efficient AC drive system and
compact gearless machines. In
2011, the Hyatt Place Waikiki
Beach Hotel underwent an elevator
modernization by ThyssenKrupp
Elevator and now the 30-year-old
elevators look, ride and perform like
new. Additionally, the operating costs
were reduced since the elevators now
use 56 percent less electricity.
Traditionally, the electricity
generated by an elevator’s braking
system was sent through a series of
resistors that dissipated the energy as
heat into the machine room.
With the introduction of
regenerative drive technology, the
energy produced by the brakes can
be fed back into the building’s power
grid (and help keep the lights on).
Since the regenerative drive captures
excess energy and reuses it, rather
than releasing it as heat, it also
reduces costly traditional cooling of
the elevator machine room.
Destination based control
software takes into account
each person’s desired stop
and dispatches the car that
will provide the fastest trip
time, reducing user wait
time up to 30 percent and
creating up to 35 percent
more efficient passenger
