A method for analytics in heating, ventilation, and air conditioning (HVAC) is described. Operation of an air-handling unit in an HVAC system is measured, including fan speed, pressure, power input, and flow. The measurements are transmitted to a processor, which analyzes the operation of the air-handling unit. The analysis includes optimizing a heuristic model of air handling in the HVAC system based on a combination of two or more of the fan speed, pressure, power input, or flow, and determining, based on the optimized heuristic model, a diversity from a fan flow set point and a fan designed maximum flow. A display presents an indication of a mismatch of a fan with a space based on the diversity. 1. A method for analytics in heating , ventilation , and air conditioning (HVAC) , the method comprising:measuring operation of an air-handling unit in an HVAC system, the measuring including fan speed, pressure, power input, and flow;transmitting measurements from the measuring to a processor; optimizing a heuristic model of air handling in the HVAC system based on a combination of two or more of the fan speed, pressure, power input, or flow; and', 'determining, based on the optimized heuristic model, a diversity from a fan flow set point and a fan designed maximum flow;, 'analyzing, by the processor, the operation of the air-handling unit bypresenting, on a display, an indication of a mismatch of a fan with a space of based on the diversity.2. The method according to claim 1 , further comprising controlling the HVAC system based on settings of the air handling in the HVAC system determined based on the diversity.3. The method according to claim 1 , wherein the heuristic model comprises a physic-based model claim 1 , and wherein optimizing comprises iteratively solving with neighbor searching or local minimization of the physis-based model.4. The method according to claim 1 , wherein the heuristic model comprises a machine-learnt classifier claim 1 , and wherein ...
