The Physics
Cubic Law = Massive Savings
The affinity law (cubic law) for fans and pumps is the most powerful single principle in building energy management: running a motor at 80% speed uses only 51% of the energy. At 60% speed, only 22%.
Most UAE buildings run AHU fans, chilled water pumps, and condenser pumps at fixed speed 24/7 — even overnight and on weekends. VFDs with BMS-integrated speed reference signals change this immediately.
