Additional Reporting for Green Star
Extra points are up for grabs if you report on additional life cycle impacts. You can select which indicators to report on at the Project Level of your project under the ‘Indicators’ tab. There are some differences in the indicators required between the different rating versions so this guide has been created for your reference.
In the eTool software, some of the indicators may vary depending on which version of the dataset you use. Note that generally, you always use the latest version of the LCI data. You only use an older version if a Design Review assessment has already been conducted using an older LCI dataset. In which case, you may use the same dataset as the previous assessment.
For Green Star v1.1, the additional indicators required are:
Up to 4 extra points are up for grabs if you report on the following 5 additional life cycle impacts for both Green Star v1.2:
For Green Star v1.3, the reporting unit for Land use has changed recently:
Please note that in eTool, the reported unit for the Land Use indicator is still based on ‘m2.year arable’. We’re waiting on further updates from GBCA before deciding if we’ll be updating this in eTool.
With the latest software updates, it doesn’t matter which version of the Default LCI dataset you’re using now, your additional indicator list should look like this in eTool:
The latest version is currently v18. Please submit a support request if you don’t have access to this version.
For the new Green Star Buildings, they’ve now added ‘Net use of fresh water’ to their main impact indicators. You no longer get any points for reporting on the other additional indicators which were needed for other GS versions.
Green Star Buildings also has a different requirement for reporting on biogenic carbon. Therefore to allow for this, you’ll need to turn on the three biogenic indicators as per the image below and have all additional indicators turned off:
Note that in eTool, our ‘Net Use of Fresh Water’ indicator is reporting in kL, not m3 however 1kL of water converts to the same amount in m3 anyway.
