Green Star – Performance assesses the operational performance of existing buildings across nine impact categories.
It is used by building owners to measure how successfully they are managing their existing assets, and helps to communicate this commitment to investors and building users. A ‘continuous improvement framework’ has been built into the tool as the certification process is on a three year cycle, this allows for improvements to be recognised over time.
Current rating tool: Green Star - Performance v1.2
Date released: 29/11/2017
Green Star – Performance can be applied as a portfolio approach as well as to a single building. The portfolio approach allows multiple assets to be assessed all at once, so each building achieves an individual rating whilst the portfolio is also given an overall score. This is especially beneficial where there are common initiatives across the portfolio (such as management policies and contracts) as they can be recognised in an efficient assessment process.
Certification with Green Star – Performance lasts three years, with an annual requirement to submit energy and water data. The certification cycle therefore allows you to be recognized for improvements over time, which can contribute to an increased star rating.
We are proud to have collaborated with the Australian Government Department of Industry, Science, Energy and Resources and NABERS to develop the Climate Active Carbon Neutral Standard for Buildings. The Climate Active Carbon Neutral Standard for Buildings provides industry a recognised, streamlined and agreed way to certify that a building is carbon neutral in operation.
We now offer a certification pathway against the standard through integration in Green Star – Performance v1.2. Buildings in operation can be assessed for carbon neutrality at the same time as seeking a Green Star – Performance rating, and benefit from synergies of parallel assessment to achieve certified ratings.

Aims to encourage and reward the adoption of practices and processes that support best practice sustainability outcomes throughout a building's ongoing operation and aims to improve a project's sustainability performance by influencing areas where decision-making is critical.
Aims to improve occupants' experience of the space, by encouraging and rewarding initiatives and measured outcomes relating to attributes that enhance the comfort and well-being of occupants.
Aims to reward building owners for implementing strategies and taking actions to measure and reduce a building's operational energy use, below that of a comparable standard-practice building.
Aims to reward projects that facilitate a reduction of building occupants' dependency on single occupant motor vehicles as a means of reducing overall greenhouse gas emissions by influencing commuting habits based on location, and on transport-related services offered.
Aims to reward building owners for implementing strategies and initiatives that reduce the consumption of potable water in building operations associated with cooling, irrigation and occupant amenities, below that of a comparable standard-practice building.
Aims to address the consumption of materials that go into, or come out of, a building during the operational phase of its life cycle, through sustainable procurement and purchasing and the management of waste.
Aims to reward buildings that minimise harm to the local ecology of the site, by discouraging environmental degradation, and by encouraging the restoration of natural environments whenever possible.
Aims to address the environmental impacts of 'point source' pollution, generated by buildings, on the atmosphere and local waterways.
Aims to recognise the implementation of innovative practices, processes and strategies that promote sustainability in the built environment.

(a general overview of resources is provided on the Resources and Roles section of our website). The table below lists all previous versions of the rating tool and their release date.
Green Star – Performance | Release date |

While the Rating Tool will be updated from time to time, project teams are only required to adhere to the Submission Guidelines for the rating tool that their project is registered under. If the project team chooses, a later version can be used. Project teams are not subject to clarifications or amendments made as part of a revision unless registered for that Rating Tool version.
Projects must be registered under the latest version of the rating tool, and project teams are encouraged to use the latest version of the tool at all times.
As the initial three year certification period comes to an end, the applicant can resubmit data for all credits as part of a new certification process and achieve a new Green Star – Performance rating. The building’s Green Star rating may increase, decrease, or stay the same, depending on any operational improvement initiatives or works the applicant may have undertaken since the last rating was achieved.
Project teams may continue to use the version of the rating tool used for the initial certification for one recertification only, after which the latest version of the tool should be used.
