Modern commercial buildings are becoming more complicated as the number of sensors, actuators and control loops increases. The building management system (BMS) used to control these components will often generate equipment faults and anomalous behaviour, which causes energy waste, thermal discomfort, and drives up maintenance costs. Such system failures may last for a long time before a facility manager or technician notices them. This necessitates the use of automated fault detection and diagnostics (AFDD) tools to detect operational faults and identify their root causes to ensure fault-free operation.

Air cooling has worked well for systems that deploy processors up to 150W, but IT equipment is now being manufactured with processors well above 150W where air cooling is no longer practical. The power for one company’s graphics processor unit (GPU) is currently at 300W. Another company produces a CPU announced at 205W and a many integrated cores (MIC) GPU announced at 320W.
