Calculators in the Green Star Online platform are only available for the following rating tools:
A number of Calculator Guides have been developed to assist project teams in understanding how to use the Green Star Calculators. All Calculator Guides can be found in the Green Star resources
Categories are sections with the rating tool that address a holistic range of sustainability impacts. Each category groups a number of issues related to a certain sustainability impact; these are known as ‘credits’.
A credit addresses an initiative that improves or has the potential to improve a project’s sustainability performance; each of these initiatives is a criterion. Credits are weighted in relation with each other by varying the number of points available. Each credit defines a clear outcome that a project must meet. Where the outcome is verified to have been met, a project will be rewarded with the relevant available points.
Once all credits are assessed, the total number of points achieved is compared against the available points in the rating tool and a certified rating is awarded. The rating describes the sustainability attributes of the project in terms that are widely understood and accepted.
For more information on credits, refer to the Introduction section of the Green Star Submission Guidelines.
A Certified Assessor is a person or persons, independent of GBCA, nominated by GBCA, knowledgeable and with experience in the green building industry, who has passed the “Green Star Accredited Professional” examination, and having undertaken appropriate and ongoing education. An Assessment Panel consists of Certified Assessor(s) and a GBCA representative. The Certified Assessor(s) will review the entire submission in their own time and meet to discuss the results of their review. A GBCA representative will also be present during each assessment meeting to record the results.
If, once you receive the results of the assessment, you are unclear as to what to submit for the next round of assessment, you can request clarification of the assessment comments. Projects are able to submit one (1) full round of clarification of assessment comments per round of assessment, meaning that all clarifications are to be provided in the one request
Download and complete the most recent version of the Clarification of assessment comments spreadsheet from Green Star resources with the credits that you require clarification on. Note: If you do not need to clarify a comment, do not include this in the spreadsheet. Ensure that you follow the instructions provided in the spreadsheet when compiling your clarifications
Note: if you do not need to clarify a comment, do not include this in the spreadsheet.
At the end of the process, you will be issued with updated results which clarify the assessment comments.
One (1) round of clarification of assessment comments per round of assessment is included in the Green Star certification fee. If an additional round of clarification of assessment comments is requested, a charge may be incurred, dependent upon the number of clarifications.
Log in to the Green Star Project Manager, and click on “New Request”, select “Ask a question” and follow the prompts. Ensure that you attach the Clarification of assessment comments spreadsheet to the request. If a project is seeking an additional round of clarification of assessment comments, please contact your GBCA coordinator to discuss prior to submitting.
Please note: a Clarification of assessment comment must be submitted within 90 days of received assessment results.
The Credit-by-Credit Assessment option was added to the Green Star certification process, to allow project teams more flexibility. A Credit-by-Credit Assessment is an optional, fee for service, step that project teams can take in order to achieve more certainty about the likely results of their assessment at any point in the assessment process*.
*Time limits may apply.
The Credit-by-Credit Assessment option is designed to make the certification process more efficient and cost-effective by helping project teams to achieve better certification results. This service will reduce the necessity of project teams to pursue expensive “buffer credits” by giving them a better indication of the likely outcome of a credit claim, prior to the regular rounds of assessment.
Undertaking this optional assessment allows project teams to submit documentation for one or more credits that they intend to claim as part of their Green Star Assessment. Any credit can be submitted however if submitting an Innovation credit for assessment, please consult your Green Star contact as Credit-by-Credit assessment is not appropriate in some situations for the Innovation Category. Individual credits can be submitted at any time throughout the certification process. The outcome of a Credit-by-Credit Assessment will be either:
*It is important to note that whilst points are conditionally awarded, the eventual allocation of credit points will be subject to a consistency review, undertaken by the Assessment Panel during the standard rounds of Assessment (Round 1 and/or Round 2).
Credit-by-Credit Assessments are subject to administration fees which are in addition to the certification fee. The cost of a Credit-by-Credit Assessment ranges from $1,000 to $3,000 per credit depending on the complexity of the credit to be reviewed.
The following rules and conditions apply to the CBCA submission submitted after Round 2:
The results of the CBCA submission automatically amend the results of the Round 2 assessment and are final.
The CBCA submission will be reviewed by third party Certified Assessor (see Certified Assessor definition), and may not be reviewed by the same Certified Assessors that reviewed the original Round 1 or Round 2 submissions.
More information will be provided to projects as needed. For more information, or to discuss how a Credit-by-Credit Assessment may help you achieve a better certification outcome for your project, or an indicative quote, please contact your Green Star contact.
An optional assessment offered as an interim step towards certification. The Designed Assessment is aimed at projects early in the design development phase where detailed information and documentation may not be available as yet.
The purpose of the Designed Assessment is to have an Assessor guide project on the likely outcome of your future Certified submission allowing projects to communicate to clients and their stakeholders that the project is on the right track (Note: the Designed Assessment is not a rating).
While the Designed assessment process is a valuable tool to ensure progress in the right direction, it does not guarantee a Certified rating. There is no requirement for a minimum number of credits for submission, however if a project would like to promote the Green Star Designed assessment result they must meet all Minimum Expectations and the minimum 15 points to achieve the Designed Assessment.
“It is noted that a simple statement of commitment will not suffice. Rather, information must be provided showing that the broad strategies and processes to deliver a certain outcome have been agreed to". (Green Star Buildings submission guidelines pg. 26)
The Designed Assessment is valid until the project achieves a Certified Rating or until 24 months after the date of practical completion occurs, whichever occurs first.
Please refer to the Submission Guidelines and our supplementary “Guidance – Submitting for Design Review” which can be downloaded from the Green Star Manager – Resources Portal.
The Design Assessment or Review is included in the Green Star certification fee. Once your project is registered with the certification fee paid, there is no additional cost for this service.

Rating Expectations are a set of criteria that must be met to be awarded distinct star ratings, in addition the number of points that must be achieved.
Rating Expectations apply to individual assets only and not to Portfolio star ratings. Rating Expectations can be found in the Introduction of the applicable Rating Tool.
Rating Expectations apply to the following rating tools:
Recertification must be achieved within five years of the initial certification and every five years thereafter until the project is fully built-out.
Where successful recertification is achieved, your project will again be provided with a licence to use the Green Star - Communities certification trademark for up to five years.
Throughout your building’s three year certification period, your team will monitor your building’s performance and where necessary implement improvements to operational procedures. As your certification period comes to an end, your team can resubmit data for all credits as part of a new certification process and achieve a new Green Star – Performance rating. Your building’s Green Star rating may increase, decrease, or stay the same, depending on any operational improvement initiatives or works you may have undertaken since your last rating was achieved.
For more information refer to your projects certification agreement, or contact the Market Engagment team on 02 8239 6200 or email.

Green Star rating tools reward sustainability outcomes and encourage moving beyond standard practice.
Projects registered under Green Star – Design & As Built, Green Star – Interiors and Green Star – Communities v1 can achieve a Green Star certified rating of 4 to 6 Star Green Star. To achieve a 4 Star Green Star rating, projects must achieve the minimum 45 points.
Projects assessed using the Green Star – Performance v1 rating tool can achieve a Green Star rating from 1 - 6 Star Green Star. To achieve a 1 Star Green Star rating, projects must achieve the minimum 10 points.
Projects registered under Green Star Buildings can achieve a Green Star certified rating of 4 to 6 Star Green Star. Projects must meet all Minimum Expectation criteria to achieve a star rating, in addition to meeting the Minimum Expectation criteria projects must achieve the minimum 15 points to achieve a 4 Star Green Star rating.
Projects assessed using the Green Star Performance v2 rating tool can achieve a Green star rating from 1 – 6 Star Green Star. To achieve a 1 Star Green Star rating, projects must achieve the minimum 1 point. In addition to the point requirements, each Star rating also has a set of Rating Expectations that projects must achieve in order to targeted Star rating.
Projects that are registered under the Green Star Homes standard do not achieve a Star rating. In order to achieve a Green Star Certified rating, all requirements from the Green Star Homes standard must be met.
This is an option where there is more than one building across a site that have similar features e.g., common systems or transport facilities. An approach like the volume certification pathway may be applied.
Log in to the Green Star Project Manager, and click on “New Request”, select “Ask a Question”, follow the prompts and select “Eligibility Query”
This certification approach is available for:
See "New Generation assessment process" definition.
A building, fitout or community is registered and submitted individually. Most projects use this certification pathway.
The Submission Portal is one method project teams can use to upload information for assessment. For ease of use, GBCA has developed instructions on how to upload your submission to the Submission Portal.
The Submission Portal is only available for the following rating tools:
For all credits, the project team must submit a Submission Template summarising the steps taken to ensure compliance with the credit criteria. The Submission Template is the principal method by which the project team communicates with the Certified Assessors. It prompts project teams for the information and narrative required to confirm that the project complies with the Credit Criteria. The Submission
Template will ask project teams to justify their claims with evidence that must be included in their submission. For more information on the Submission Templates refer to the introduction section of the Submission Guidelines, and view the Submission Template on the GBCA website.
Submission Templates are available in the Green star resources for the following rating tools:
For all rating tools, there are a set of timing requirements to be considered when preparing to submit documentation for assessment. These requirements are outlined in the Certification Agreement and can also be found in the relevant Submission Guidelines of the rating tool that your project has registered for.
If the occasion arises where a project is unable to meet the submission timing requirements, contact the projects GBCA contact to discuss your options and submit an Eligibility Query for GBCA review. Please note that the submission timing requirements, do not supersede the important deadlines.
Technical questions are submitted when you require further clarification on an item within a credit, or if you would simply like to confirm that your interpretation is correct, or you're proposing an alternative solution to the credit requirements. Technical Clarifications and Credit Interpretation Requests, terms included in the certification agreement, are technical questions.
Responses typically include:
Technical questions are $220 (excl. GST) each.
Log in to the Green Star Project Manager, and click on “New Request”, select “Ask a question” and follow the prompts.
This is an option where there are projects with common characteristics. The approach is to identify “common credits” across projects. The credits are assessed against documentation pertaining to one project with the results applied to other projects deemed to share the same features. A quality assurance check is applied to each project to ensure compliance with the awarded common credit.
This may be applied, for example, where retail fitouts are almost identical, or two or more buildings or precincts share many common characteristics. Green Star Homes is designed for a volume approach.
In order to maintain your building’s Green Star – Performance certified rating, the project team must submit greenhouse gas and potable water performance data at 12 and 24 months intervals following the end of the certified building’s Performance Period.
A 12 month ‘Performance Period’ is the period of time for which your project team gathers and collates auditable data about the operational performance of your building and for the period for which your building is assessed.
Once your building’s performance period is complete, your team has 90 days to submit your documentation. Like other Green Star rating tools, there are two rounds of assessment available to help you demonstrate your building’s performance.Where a second round of assessment occurs, your team must submit your building’s Round 2 documentation no more than 90 days following receipt of your Round 1 assessment results.
A Green Star – Performance Rating is valid for a period of three years upon Certification and may change due to the ongoing performance of the building.
In order to maintain your building’s Green Star – Performance certified rating, the project team must submit greenhouse gas and potable water performance data at 12 and 24 months intervals following the end of the certified building’s performance period.
These simple checks are submitted to GBCA and help to demonstrate that the building is operating at the level at which it was certified, and that the applicant is undertaking appropriate monitoring for key performance indicators and impact categories.
