31  Equation 7—baseline overall energy efficiency of installed HE fan (𝜂B,i)
  For equation 3, 𝜂B,i is worked out using the equation (equation 7):
  where, for the ith installed HE fan:
CB,i is the part‑load compensation factor for the baseline fan control system, and is:
 (a) if a variable speed drive was already installed—equal to CC,i as given by equation 8 (subsection 32(1)); and
 (b) if a multi‑speed or switching control was already installed—equal to CC,i as given by equation 9 (subsection 32(2)); and
 (c) otherwise—equal to 1.
ai is a regression coefficient, and is determined in accordance with Schedule 4.
ln(PE,i­) is the natural log of the motor input power (PE,i), in kilowatts, of the fan, where PE,i has the same meaning as in section 27.
bi is a regression constant, and is determined in accordance with Schedule 4.
NAve,i is the market average efficiency grade of the fan, and is determined in accordance with Schedule 5.
