An average building may contain hundreds of motors, whirring and chugging away unseen. Most of them are used in heating, ventilating, and air conditioning applications as drivers for fans, pumps, and air conditioning compressors. Others power elevators and escalators. And altogether they use significant amounts of electricity. The National Energy Information Administration  reports that in the five-state Pacific region that includes California, electric motors account for about 23 percent of all electricity consumed in commercial buildings. Despite this statistic, building designers often neglect to carefully select and size them-as evidenced by the prevalence of oversized, inefficient induction motors in California building stock.
