Green Star FAQs


FAQ 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 Climate positive buildings and our net zero ambitions available on the GBCA website.
