Otis is developing innovative products that are more energy efficient, according to Bill Evans, Otis vice president of product management.Among these new products is the recently introduced Gen2 machine-roomless elevator system, which incorporates a permanent-magnet motor and flat coated steel belts that reduce overall energy demands.
"In addition to this, we have been incorporating VF (variable frequency) drive benefits into our products for upgrading existing elevators so the building owner can have an energy efficient elevator system similar to that of a new installation," said Evans.
The Gen2 system stands as one of the most energy efficient elevators.It is as much as 50% more efficient than conventional designs, and the system's VF drive also features a sleep mode for further reduction in power consumption.
In China, where developers envision a motor vehicle for every household by the year 2010, building owners are very concerned about their dependence on fossil fuels, and they are looking for ways to save energy.

"We see our customer relationships as long-term building-management partnerships," said Evans."Our goal is to help our customers manage energy conservation for the life of their buildings."
Power Outages And Elevator SafetyTo help customers manage in the event of a power outage, Otis has developed a list of safety tips for building owners and the riding public.
"We are working closely with our customers worldwide to help them operate their elevators safely and with energy conservation in mind," said Bill Evans, Otis vice president of product management.
Most elevators will not operate during power outages, although they are designed to stop safely if a building loses power.Many major buildings have battery back-up systems that can bring the elevator to the next floor and open the doors to allow passengers to exit.If there is no back-up system, passengers are still very safe inside a stalled elevator, according to Evans.
Air circulation in an elevator car is not a problem, and the best thing for passengers to do if they are trapped in an elevator is to wait for help to arrive.
"It is very dangerous to try to force your way out of the car," Evans said.
In the event of an outage, Otis offers these tips to the riding public:
Listen to local newscasts for updates about planned local outages.Do not use an elevator if there is the possibility of a power outage.If you are stuck in an elevator during an outage, stay calm and don't panic.Do not force open the doors to crawl out between floors or climb onto the roof.
