components recycled.\n\n (3) However, the equipment may be sold to a third party to be broken down and recycled as described in paragraph (2)(b).\n\nPart 4—Net abatement amount\n\nDivision 1—Preliminary\n\n11  Operation of this Part\n\n  For paragraph 106(1)(c) of the Act, this Part specifies the method for working out the carbon dioxide equivalent net abatement amount for a reporting period for a commercial buildings project that is an eligible offsets project.\n\n12  Overview of gases accounted for in abatement calculations\n\n  The following table provides an overview of the greenhouse gases and emissions sources that are relevant to working out the carbon dioxide equivalent net abatement amount for a commercial buildings project.\n\n \n\n- Greenhouse gases and emissions sources\n- Item Relevant emissions calculation Emissions source Greenhouse gas\n- 1 Baseline emissionsProject emissions Electricity consumption Carbon dioxide (CO2)Methane (CH4)Nitrous oxide (N2O)\n- 2 Baseline emissionsProject emissions Fossil fuel combustion Carbon dioxide (CO2)Methane (CH4)Nitrous oxide (N2O)\n\n\n13  Buildings to be used in calculations\n\n (1) For the purposes of working out the carbon dioxide equivalent net abatement amount for a reporting period, the project proponent for the project may choose not to calculate abatement for a building in the project for a measurement period in the reporting period.\n\n (2) However, if:\n\n (a) the project proponent undertakes an activity (whether or not a project activity) at a building in the project; and\n\n (b) under legislative rules made for subparagraph 27(4A)(c)(ii) of the Act, the activity must not be included in an eligible offsets project; and\n\n (c) the activity could reasonably be expected to have an effect, that is not minor or trivial, on the abatement that would be calculated for the building in the measurement period;\n\nthe project proponent must not calculate abatement for the building for the measurement period.\n\n14  Data to be used in calculations\n\n  When data about energy consumption at a building or the configuration of the building is to be used to work out the carbon dioxide equivalent net abatement amount for a reporting period, the project proponent for the project must only use the following data:\n\n (a) data that:\n\n (i) is recorded in the NABERS energy rating report for the building; or\n\n (ii) can be derived from the data recorded in the report;\n\n (b) data that is derived from a NABERS energy reverse calculator;\n\n (c) for renewable electricity generated and consumed onsite at the building—data that is:\n\n (i) monitored in accordance with the monitoring requirements; or\n\n (ii) worked out in accordance with section 15.\n\n15  Data for renewable electricity generated and consumed onsite at a building\n\n (1) If, for a particular period (the non‑monitored period), a project proponent chooses to work out data for renewable electricity generated and consumed onsite at a building in accordance with this section, the renewable electricity generated and consumed onsite at the building during the non‑monitored period is taken to be equal to the difference between:\n\n (a) the total amount of renewable electricity generated by the equipment, mentioned in paragraph (a) of the definition of renewable electricity generated and consumed onsite, during the non‑monitored period; and\n\n (b) the total amount of electricity exported from that equipment to the electricity grid during the non‑monitored period.\n\nNote: The non‑monitored period may be the whole measurement period.\n\n (2) The amounts of electricity mentioned in paragraphs (1)(a) and (b) must be worked out:\n\n (a) in accordance with paragraph 33(a) or (b); or\n\n (b) using billing data.\n\nNote: Different methods can be used to work out the amounts.\n\n (3) If:\n\n (a) billing data is used to work out an amount mentioned in paragraph (1)(a) or (b) for a non‑monitored period; and\n\n (b) there is available data, for time periods, about:\n\n (i) renewable electricity generated by the equipment mentioned in paragraph (1)(a); or\n\n (ii) electricity exported to the electricity grid by the equipment mentioned in paragraph (1)(a); and\n\n (c) the time periods do not start and end on the same days as the non‑monitored period starts and ends; and\n\n (d) together the time periods cover the non‑monitored period;\n\nthe project proponent for the project may pro‑rata the relevant data for a time period based on the number of days in the time period that are days in the non‑monitored period.\n\n (4) For subsection (3):\n\nrelevant data means:\n\n (a) for working out the amount mentioned in paragraph (1)(a)—billing data about renewable electricity generated by the equipment mentioned in paragraph (1)(a); or\n\n (b) for working out the amount mentioned in paragraph (1)(b)—billing data about electricity exported to the electricity grid by the equipment mentioned in paragraph (1)(a).\n\n16  Previous NABERS energy rating to be used in calculations\n\n (1) For the purposes of working out the baseline NABERS energy rating for a building in relation to a measurement period in the reporting period under section 22, the previous NABERS energy rating used for the building must be the most recent one that meets all of the requirements in this section.\n\nNote: If the previous NABERS energy rating used for the building does not meet all the requirements in this section, abatement cannot be calculated for the building for the measurement period.\n\n (2) The previous NABERS energy rating was for the same type of commercial building as is the type of the building in the measurement period.\n\n (3) The previous NABERS energy rating covered an area:\n\n (a) containing, or serviced by, energy‑consuming equipment; and\n\n (b) that is the same area, or is substantially the same area, as is covered by the NABERS energy rating for the building in the measurement period.\n\n (4) For paragraph (3)(b), an area is substantially the same area if the size of the area has changed by no more than 10%.\n\n (5) If the building is an office building, the previous NABERS energy rating was for the same type of NABERS (office) energy rating (a base building, a tenancy, or a whole building) as is covered by the NABERS energy rating for the building in the measurement period.\n\nDivision 2—Method for calculating net abatement amount\n\n17  Summary\n\nThe carbon dioxide equivalent net abatement amount for a project for a reporting period is the sum of abatement for buildings in the project over measurement periods in the reporting period.\n\nAbatement for a single building is:\n\n (a) if certain conditions are met for achieving a minimum abatement amount for the building, and the difference between baseline emissions and project emissions for the building is equal to or greater than zero—the amount of that difference; and\n\n (b) otherwise—zero.\n\n18  Carbon dioxide equivalent net abatement amount\n\n  The carbon dioxide equivalent net abatement amount
