Additional Reporting for Green Star

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.

Green Star v1.1, v1.2 & v1.3

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.

Additional Indicators List 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 v19. Please submit a support request if you don’t have access to this version.

Green Star Buildings

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.

    Also, you should update to V14 for this project, there was some really significant improvements to V14 that were identified with a new QA/QC process eTool started undertaking.

    Hi Marie,

    Good question. I am fairly confident that we Green Star will accept the newer units, particularly because this is not one of the core indicators but rather an additional one. If you do run into issues with the certifier please let me know and I’ll make enquiries with the GBCA on this.

    My project is using GS D&AB v1.1 where Human Toxicity is required in kg 1,4 DB equivalent and I am under v13 in eTool. For v13, you only refer to GS v1.2 and v1.3. So what about v1.1?

    Is it compliant to report Human toxicity cancer and non cancer in CTUh when the requirement is for kg 1,4 DB equivalent? Did you have this case before?

    Many thanks,
