Fan units to be used in calculations

For the purposes of working out the project abatement amount for a reporting period, the project proponent must include only fan units that are in commission before the end of the reporting period.

The proponent may choose not to include a particular fan unit in the calculations for the period.

The project proponent must not include a fan unit in the calculations for the period if, at any time during the reporting period, any of the following circumstances apply:

the unit was decommissioned or removed from the building or refrigeration system; the building or refrigeration system to which the unit relates is not used for the majority of the reporting period;the unit was modified in a way that resulted in the unit consuming more energy to provide the same function.

Data to be used in calculations

In calculating the energy consumption of the project, the project proponent must, for each refrigeration fan unit or ventilation fan unit use only the following data:

the supplier’s product specifications for the unit; orstandard test reports for the unit that comply with ISO 5801.

—Calculating project abatement amount

Summary

The project abatement amount for a project is the sum of the abatement during the reporting period resulting from each replacement or modified fan unit produced by the project.

Equation 1—project abatement amount (A)

The project abatement amount for a reporting period is worked out using the formula (equation 1):

A=∑i=1

n

A i

where:

A is the project abatement amount for the reporting period in tonnes CO2-e.

n is the number of replaced or modified fan units over which abatement is measured for the reporting period.

Ai is the abatement, in tonnes CO2-e, for the ith fan unit of the fan unit upgrade project for the reporting period, calculated using:

for a ventilation fan unit—equation 3.

Equation 2— abatement for refrigeration fan unit (Ai)

For section 18, Ai for the ith refrigeration fan unit, is worked out using the formula (equation 2):

Ai= ( Pi×(ai – CFi)+bi ) ×(1+(1

CO Pi))×t i ×24 ×10−6 × EFelec , i

where:

Pi is the motor input power of the ith fan unit, in watts.

ai is the regression coefficient in column 3 of Schedule 1 that corresponds to the motor input power of the ith fan unit.

CFi is the control factor in column 3 of Schedule 2 that corresponds to the control system of the ith fan unit.

bi is the regression constant in column 4 of Schedule 1 that corresponds to the motor input power, in watts, of the ith fan unit.

COPi is the coefficient of performance in column 3 of Schedule 3 that corresponds to the type of refrigeration system in which the ith fan unit is installed.

ti is the period, expressed in days, within the reporting period that the ith fan unit was in commission.

EFelec,i is:(a) for electricity obtained from an electricity grid that is a grid in relation to which the

NGA Factors document in force on the declaration day includes an emissions factor—that factor, in kilograms CO2-e per kilowatt hour; or

(b) for electricity obtained from an electricity grid not covered by paragraph (a) or from a source other than an electricity grid:

(i) if the supplier of the electricity is able to provide an emissions factor that reflects the emissions intensity of the electricity and is applicable on the declaration day—that factor, in kilograms CO2-e per kilowatt hour; or

(ii) otherwise—the emissions factor, in kilograms CO2-e per kilowatt hour, for off-grid electricity included in the NGA Factors document in force on the declaration day.

For subparagraph (b)(i) of the definition of EFelec,i, the emissions factor must be worked out:

(i) on a sent-out basis; and(ii) using a measurement or estimation.

Equation 3—abatement for ventilation fan unit (Ai)

For section 18, Ai, in relation to the ith ventilation fan unit, is worked out using the formula (equation 3):

Ai= ( Pi×(ai – CFi)+bi ) ×t i

365× AOH i ×10−6 × EF elec ,i

where:

Pi is the motor input power of the ith fan unit, in watts, at full throttle with the impeller fitted.

ai is the regression coefficient in column 3 of Schedule 1 that corresponds to the motor input power of the ith fan unit.

CFi is the control factor in column 3 of Schedule 2 that corresponds to the control system of the ith fan unit.

bi is the regression constant in column 4 of Schedule 1 that corresponds to the motor input power, in watts, of the ith fan unit.

ti is the number of full days in the reporting period that the ith fan unit was in commission.

AOHi is the annual operating hours in column 4 of Schedule 4 that corresponds to the BCA building classification in column 2 of Schedule 4 and activity in column 3 of Schedule 4 applicable to the building in which the ith fan unit is installed.

EFelec,i has the same meaning as in equation 2.

In determining AOHi for subsection (1), if more than one BCA building classification applies to the building, the BCA building classification with the lowest annual operating hours applies.
