RIVERSIDE, Calif. — While motors that run heating, ventilation and air conditions are the largest users of energy in buildings, motor-related efficiency requirements are ‘relatively lax,’ according to researchers at the University of California, Riverside.

“Electric motors are by far the largest energy user in any building but get very little attention regarding efficiency and energy use,” said Sadrul Ula, research faculty at the university’s Bourns College of Engineering Center for Environmental Research and Technology.
