F-00126 - Minor amendment to the reverberation credit in Green Star - Design & As Built v1.2 and Green Star - Interiors v1.2
For projects registered under the Green Star - Design & As Built v1.2 and Green Star - Interiors v1.2 rating tool, for the credit criteria 10.2 Reverberation in Design & As Built v1.2 and 9.2 Reverberation in Interiors v1.2: Where the submission guidelines make reference to note 3 of Table 1 AS/NZS 2107:2016, the GBCA clarifies that this is a minor discrepancy in the submission guidelines. The reference should be made to note 1 of Table 1 AS/NZS 2107:2016 in both the Green Star - Design & As Built v1.2 and Green Star - Interiors v1.2 rating tool.  Please include a copy of this response in your submission.

F-00118 - Can petroleum hydrocarbons and free oils be excluded from pollution reduction targets?
No. While petroleum hydrocarbons and free oils cannot be readily modelled in MUSIC at the time of publishing this FAQ, it is possible to address petroleum hydrocarbons and free oils via stormwater treatment devices such as gross pollutant traps (GPTs).  Reduction targets for total petroleum hydrocarbons and free oils are not applicable for projects where the site contains less than a total of 200m2 of uncovered areas where vehicles are likely to transit and/or park (e.g. roads, loading docks, refuelling bays, car parking, etc).

F-00115 - Can off-site renewable energy (e.g. GreenPower) be apportioned over the length of the building power supply contract?
Yes. For projects targeting the reference building/fitout pathway, where the percentage of offsite renewable energy is procured in stages over the length of the supply contract the effective percentage of the supply contract can be applied. This is done by multiplying the percentage of off-site supply by the percentage of the contract length for which this uptake will be relevant. For example: A power supply contract for a project that achieves Practical Completion in Jan 2019 is in place for 5 years (under Interiors v1.2) from 2019 to 2023. If the renewable supply will be 20% from Jan 2019 to Dec 2020 (40% of contract length) and then 70% from Jan 2021 to Dec 2023, the effective off-site renewable percentage shall be calculated as: 0.2(0.4) + 0.7(0.6) = 50% The effective off-site supply percentage will be entered into the 'Percentage GreenPower® within the building's power supply contract' cell within the Energy Consumption and Greenhouse Gas Emissions Calculator.  Please refer to the 'Accredited GreenPower® products' section located under the GHG Emissions Credit to find more information on the minimum power supply contract length for either Fitouts or Design & As-Built projects. Projects will not be rewarded for off-site energy supply beyond the nominated five or ten year period immediately following Practical Completion.  For further information on what off-site renewable energy supply is eligible in Green Star, please refer to the Renewables and Offsets in Green Star Fact Sheet available on the GBCA website.

F-00125 - Can I target a stepped point scale for the Reduced Peak Electricity Demand credit?
Yes, project teams may use the stepped scale outlined below for credit 23A Reduced Peak Electricity Demand - Performance Pathway within the Green Star - Communities v1 and v1.1 rating tool. Project teams may target:  1 point where it is demonstrated that the project's predicted peak electricity demand has been reduced by 12.5% when compared to that of a reference project.  2 points where it is demonstrated that the project's predicted peak electricity demand has been reduced by 25% when compared to that of a reference project.  Please note: there are no partial points awarded for this credit.  All compliance requirements are as per the Submission Guidelines.

F-00112 - Can I claim 1 innovation point for using 750 MPa steel fitments of reduced diameter on my project?
Yes, projects may pursue one (1) innovation point through 30A Innovative Technology or Process where the use of 750 MPa steel fitments of a reduced diameter are installed in lieu of equivalent 500 MPa fitments** (also known as ligatures) under the following conditions: A minimum of 70% of the structural columns for the entire building, by length, are concrete and require steel reinforcement; and 95% or more of the fitments used in these columns are ≥750 MPa replacing the equivalent 500 MPa fitments**; and 95% or more of the fitments are supplied by a Steel Maker that meets the Responsible Steel Maker requirements in the Responsible Building Materials (20.1) credit; and the fitments supplied meet Australian Standard AS 3600-2018 and have a CEV value not exceeding 0.49; and is a trademarked product; and  The project team achieves either One (1) point in the Reduced Use of Steel Reinforcement (Concrete framed building) credit (19B.2B) not including the reduction in mass of fitments; or An improvement of 4% in the Climate Change Impact category of the Life Cycle Assessment credit (19A) across all modules as a whole, excluding the B6 Operational Energy module. Documentation requirements Project teams wishing to pursue this innovation point are required to provide the following documentation: Structural engineer's specification Drawings & summary demonstrating the percentage of columns requiring fitments/ligatures Completed spreadsheet Steel_reduction_500N_to_750N_fitments_template.xlsx demonstrating the reduction in mass based on replacing 500 MPa with the smaller, higher grade 750 MPa fitments Delivery docket and/or invoice confirming supply Evidence of Responsible Steel Maker requirements Evidence the fitments were produced in line with AS 3600-2018 Evidence of the product's trademark in line with the conditions outline 30A Innovative Technology and Process submission template, specifying the pathway achieved,i.e 19A or 19B.2B. Notes: *The validity of this innovation claim will be reviewed in May 2021, 2 years after initial publication in May 2019. Projects registered during this time can pursue this innovation beyond this date. This innovation claim is only available to projects registered to Green Star - Design & Built v1.2 and beyond.  **Replacement values: 500 MPA 10mm diameter can be replaced by 750 MPa 8.2mm dia500 MPA 12mm dia can be replaced by 750 MPa 9.8mm dia500 MPA 16mm dia can be replaced by 750 MPa 13.1mm dia
