Mitsubishi Electric Develops Elevator Control System to Reduce Power Consumption

Japan's Mitsubishi Electric Corp. has developed a multi-elevator control system that helps reduce the power consumption of elevators, according to an announcement on January 14, 2010. A simulation study conducted by the company shows that this system can reduce daily energy consumption by up to 10 percent (about 10 kilowatt-hours, equal to 5.55 kilograms of carbon dioxide) in a typical 16-storey building with four elevators.

Existing multi-elevator control systems are designed to prioritize users' convenience by efficiently operating multiple elevators to minimize their waiting time, which is more likely to increase energy consumption for elevators on the whole.

Meanwhile, with this latest system, when a user presses an elevator button, the elevator that best balances operational and energy efficiencies is selected, based on each elevator's potential energy consumption according to its location and passenger load. The system prioritizes operational efficiency during peak hours in the morning, evening, and at lunchtime, whereas it prioritizes energy efficiency during off-peak hours.

Mitsubishi Electric plans to sequentially introduce elevators equipped with this system in both domestic and overseas markets, starting in April 2010.
