2  Equation 12—determining operating efficiency of fan (𝜂Operating,i)
  The operating efficiency of a particular fan i, 𝜂Operating,i, is worked out using the equation (equation 12):
  where:
𝜂i is the overall driven fan efficiency of the fan, and is:
 (a) if the model of the fan was tested with the same drive, motor and transmission as the fan (see paragraph 16(4)(b) of this determination)—the overall driven fan efficiency given by equation 13; and
 (b) otherwise—the overall driven fan efficiency given by equation 14.
CC,i is the part load compensation factor for the controller of the fan, and is:
 (a) if the motor is controlled by a variable speed drive that is to be installed as part of the project—the value given by equation 16 (subsection 5(1) of this Schedule); and
 (b) if the motor is controlled by a multi‑speed control or a switching control that is to be installed as part of the project—the value given by equation 17 (subsection 5(2) of this Schedule); and
 (c) otherwise—1.
