All three elevators in the building have regenerative braking technology which allows them to recover energy on their “light” cycles. If the lift goes up empty, the counterweight is heavier than the carriage, and the regenerative drive produces electricity for the building. Conversely, if the lift goes down with 6.5 or more people inside, it is heavier than the counterweight, and it will produce electricity for the building. This technology saves up to 30% of the energy that a conventional lift would use.
