Registering a project for Green Star does not guarantee certification. Projects must ensure they also meet the Eligibility Criteria current at the time of registration as well as achieve the relevant number of points for a rating.

At any point in the certification process, project teams can submit a ‘Project Eligibility Query’ free of charge.


Eligibility criteria


All buildings aiming to achieve a Green Star – Interiors rating are subject to the following eligibility criteria:




Fitout type


Green Star – Interiors is intended to rate building fitouts. The majority of fitout types are eligible to be rated including mixed use developments comprising of more than one of the following BCA space use classifications - BCA Class 3, 5, 6, 8, 9a,9b,9c.


Timing of submission for certification


Submissions for a Green Star - Interiors certification can be lodged following practical completion of the project. The certified rating will only be awarded within 24 months of practical completion.



Conditional requirements


A project seeking certification must meet the conditional requirement criterion outlined in the 'Greenhouse Gas Emissions' credit. A project will not be eligible for a Green Star certified rating unless the benchmarks in this conditional requirement have been met.



Distinct boundary


Project certification must apply to an area/site that is clearly distinct. Project components are not eligible. Shared building services or amenities such as waste rooms or bicycle facilities do not affect the building’s eligibility.Sub-tenancies are considered part of the fitout and cannot be excluded from the rating



Other requirements


Projects must comply with all legal requirements in respect of their project (e.g. BCA requirements or Occupational Health & Safety requirements).

Further requirements are set out in the Certification Agreement.


Certification process



New Generation Assessment process

We’ve simplified and improved the assessment process for New Generation Rating Tools to make it more efficient, more effective and to help achieve better outcomes.

There are two methods of assessment used in the certification process.

Core assessment: Information provided in the Submission Template is reviewed for compliance.

Comprehensive assessment: Information provided in the Submission Template as well as supporting documentation is assessed for compliance.

The diagram below outlines the stages at which each method of assessment is used.

Determining Compliance

Once assessed, Criteria claimed will either be:

  1. Awarded
  2. Awarded – minor non-compliance:
    Insignificant errors identified within the submission, and the points are still awarded.
  3. Not Awarded – major non-compliance:
    Significant errors identified within the submission, and the points cannot be awarded.


Assessor Interaction

The Assessor Interaction process has been introduced to the Green Star certification process with the aim of facilitating more productive communication between the third party Green Star Certified Assessors and the project teams engaged to undertake a Green Star submission. Opening up the communication for both the Assessors and the project team will improve the quality of the Green Star assessment experience for all involved. A GBCA representative will always be present at any Assessor Interaction between the Assessor and the project contact (usually the GSAP).

The Assessor Interaction process is an opportunity for a project contact to discuss with the Certified Assessor comments in the results, or project subtlety not easily conveyed with submission documentation, and if the usual processes do not adequately facilitate clarity of documentation requirements for the project team. Please note that the Assessor Interaction is not used in place of a submission. Documentation for assessment must still be provided within the submission.

The Assessor Interaction process may be held one month prior to Round 1, and/or within one month of the Round 1 assessment results having been sent. The opportunity to conduct a meeting at other stages of the certification process may be available at the discretion of the GBCA.

If you would like to discuss setting up a meeting for your project please contact your project Case Manager for more details.




Certification fees


The certification fee for Green Star – Interiors is based on the project’s contract value*, and GBCA membership status. To receive the member rate the applicant company must be a member. To become a GBCA member please register your organisation.

Things you need to know:

  • Once a project is registered there is a no-refund policy.
  • Projects will not be assessed until payments for all outstanding invoices have been received.

* Fees are subject to change without notice.
* The project contract value is defined as the dollar value required to complete the works for the entire project, including site works. The following may be excluded when determining total contract value:

  • Demolition works
  • Consultants, design fees, project management fees
  • Works outside the site area
  • Buildings or areas within the site that are not being assessed for purposes of Green Star

Where a number of amenities or services are shared between stages in a larger development, the GBCA expects that the cost apportioned to the rated stage is equivalent to the use that the stage will have of these facilities.
