The Grand Bratislava Hotel, which has three floors, has requested that its elevator maintenance person decrease the speed of the hotel’s elevator by half. The elevator already meets safety requirements, and the change will cause the elevator to use slightly more energy per trip between floors. Nonetheless, the hotel’s management expects the hotel’s energy efficiency to increase as a result of the change without any concurrent change in other operating habits.
Which of the following, if true, provides the best reason for the expectation?
【选项】
