Green Star FAQs

17A Sustainable Transport Calculator

Project teams can download the calculator from the Resources portal to obtain the calculator outputs.

Project teams will need to obtain the project's score from the WalkScore ® website or follow the method outlined in FAQ 179. The calculator inputs and layout have been updated to make it clear the information required to complete the calculator.

Note: A technical question is no longer required to access the 17A Sustainable Transport Calculator for registered or non-registered projects. If a project's location or Statistical Area 2 (SA2) cannot be found in the updated calculator, please submit a Fix/Modify a Calculator/Scorecard request with the registered project's full address.

17B Access by Public Transport Calculator

Registered Green Star projects will still need to submit a technical question (free of charge) through the Green Star Manager to request the Access by Public Transport Calculator. 

Please include the following in your request in order for the calculator to be provided:

• Green Star number
• Project Name
• Project Address (not geocode)
• Type of project. e.g. office, retail, etc.
• Number of occupants (if the project is a mixed use development, please specify the number of occupants for each type, i.e Office/retail).

Results will be issued as a PDF for use in the project submission. 

The calculator is required to be provided on request due to the calculator being dependent on external software which is pay-per-use. All costs associated with running the Access by Public Transport calculator for registered projects will be absorbed by the GBCA.

Note: Projects that have not registered with the GBCA to obtain a Green Star rating are not eligible to submit a request.
