How much can you save?
KONE MonoSpace elevators can reduce the total energy consumption of the elevator by as much as two-thirds or even more. For example, a KONE C-series elevator, with the KONE MiniSpace™ platform and the KONE EcoDisc® drive, uses a total of about 6900 kWh of electricity a year – about half as much as a DC gearless elevator and one-third as much as a geared (TAC) elevator. With additional energy-saving features, this energy consumption can be reduced still further.
Regenerative drive
When the car is going down with a heavy load, it contains potential energy. The regenerative drive recovers this energy. It can save up to 25% of the energy consumed by a typical 14 person KONE MiniSpace elevator. |

A green hoisting system
The KONE EcoDisc® hoisting machine made DC gearless and energy-hungry geared hoisting machines obsolete. The KONE EcoDisc® permanent magnet synchronous machine, together with a vector controlled drive system and regenerative options, provides the highest total efficiency and minimizes both mechanical and electrical losses. |

Eco-efficient car lighting
To save energy used for car lighting halogen lights have been replaced by LED spot lights. LED lights consume 80% less electricity than halogen lights and last up to 10 times longer. Modern fluorescent light technology is also available for KONE C-series elevators. |
Put to sleep when not in use
In today’s elevators, lights, signalization and ventilation can consume a considerable amount of electricity even when the elevator is not moving. KONE energy-efficient options supervise elevator usage and set the devices to sleep mode during inactive periods to minimize total energy consumption. |

It’s not only the motor that consumes electricity
The energy needed for lighting and hoisting can be reduced by using LED lights and regenerative drive options. The potential savings can amount to 600 to 1500 kWh using LED lights and standby operation.

KONE EcoDisc® regenerates electricity
KONE EcoDisc®, together with a regenerative drive option, works as a generator when a heavy car is returned to ground floor or empty car going up. Instead of turning the braking energy to heat, the electricity is fed back to the network.
