“The aim of architecture is to elucidate the objectification of the will
at the lowest grade of its visibility and to present it in the most definite way,
to make the dumb will speak perceptibly, to bring the inaudible
audibly and visibly before our eyes.”
— Die Welt als Wille und Vorstellung
Johann Christoph Friedrich Wilhelm Schopenhauer

ABSTRACT. The present study focuses on the effect on power consumption and analysis of the amount of regenerative power that could be generated after the regenerative drives of elevators have been installed. The elevator regenerative drives transform gravitational potential energy into electrical energy by utilizing elevators’ operation characteristics and weight difference between carriage and counterweights. The regenerative power is then fed back into electrical grid of a building and afford other electrical equipment to achieve energy saving. This paper investigates the operating principle of elevators, describe the mechanism of regenerating power, distinguish the terminologies of the power saving rate and the regenerative energy ratio, and finally use a power analyzer to monitor the experimental data of an elevator before and after installing a regenerative power drive.
