3 C H A P T E R 2 Escalators and moving walkways can account for 3 to 5 percent of electric energy use in airports.1 Components impacting energy use primarily consist of motors, controls, and lighting. Escalators and walkways consume energy based on the run time and the number of people utilizing them at a given time, which makes determining energy savings opportunities unique to each installation.

4 Airport Escalators and Moving Walkways -- Cost-Savings and Energy Reduction Technologies of speed change when passengers are riding the escalator and that the rate of change of speed of the escalator is sufficiently gradual so as not to cause loss of balance should a passenger bypass the detection means, yet sufficiently rapid to attain full speed when an approaching passenger is detected." As of this report's submission, many states have not adopted the 2010 version of ANSI/ ASME A17.1. However, escalators and moving walkways with variable speeds can be installed pending permission from individual airport governing bodies.

Background 5 Many energy savings technologies that have been installed in Europe and Asia (e.g., intermittent drives for two-speed operation and start–stop operation) have not yet been installed in the United States in large quantities.
