Sustainability in interior fitouts

Green Star – Interiors assesses the sustainability outcomes of interior fitouts across nine holistic impact categories.

The current version of the rating tool is: Green Star – Interiors v1.2. This was released on 03/07/17.

The nine categories and credits


Aims to encourage and reward the adoption of practices and processes that support best practice sustainability outcomes throughout the different phases of a project’s design, construction and ongoing operation.

Indoor environment quality (IEQ)

Aims to encourage and reward initiatives that enhance the comfort and wellbeing of occupants. The credits within this category address issues such as air quality, thermal comfort and acoustic comfort.


Aims to reward projects that are designed and constructed to reduce overall greenhouse emissions from operations by addressing energy demand reduction, use efficiency and generation from alternative sources.


Aims to reward projects that facilitate a reduction on the dependency of private car use as an important means of reducing overall greenhouse gas emissions, as well as to encourage the provision of alternative forms of transportation.


Aims to encourage and reward initiatives that reduce the consumption of potable water through measures such as the incorporation of water efficient fixtures and building systems and water re-use.


Aims to address the consumption of resources for the project, by encouraging the selection of low-impact materials.

Land use and ecology

Aims to reward projects that minimise harm and enhance the quality of local ecologies.


Aims to assess the environmental impacts of 'point source' pollution generated by projects and reduce their effects on the atmosphere, watercourse and native animals.


Aims to recognise the implementation of innovative practices, processes and strategies that promote sustainability in the built environment.

Innovation Challenges, found in the Innovation category, are designed to encourage and direct investment in solutions that address a wide range of social, economic and environmental sustainability issues. Some Innovation Challenges take the form of new credits, while others simply identify sustainability issues that additional research and innovation will help to address.

Projects must submit these Submission Templates provided and are not permitted to use an alternative document.
Submission Templates are provided in MS Word format. Please note there are no automated or 'smart' features embedded within the Submission Templates. Project teams are to fill in and edit the Submission Templates to suit their responses within the shaded areas indicated within each Submission Template. Feedback on these templates are welcomed.

Sustainable materials additional support and guides

The Green Star materials category consist of credits that facilitate and recognise the efficient use and management of building and fitout materials. In order to assist project teams, the GBCA has made improvements and developed additional reference material.

Life Cycle Assessment (LCA) and Environmental Product Declarations (EPD): Products and materials in Green Star rating tools are addressed by Credits which target the consumption of resources through selection, use, reuse and efficient management practices of building and fitout materials. The GBCA has developed some background and guidance relating to Life Cycle Assessment, and Environmental Product Declarations, when submitting documentation within Green Star credits.

PVC: PVC products using the in construction of buildings and fitouts are considered within Green Star rating tools, namely within the Best Practice Guidelines for PVC credit. Based on industry feedback, the GBCA has developed guidance on demonstrating compliance with the Green Star credit.

Construction and demolition wasteAll Green Star rating tools include a Construction and Demolition Waste credit which aims to encourage and reward management practices that minimise the amount of construction and demolition waste from base building and/or interior fitout works that is disposed to landfill. The credit requires the use of waste contractors and waste processing facilities that have been independently verified for compliance with minimum standards of reporting. As a result of this consultation process, in 2013 the GBCA introduced the Construction and Demolition Waste Reporting Criteria for projects seeking Green Star certification.

Product Certification Schemes: The GBCA has developed a framework to acknowledge products certified by product certification schemes within the Materials category (Material Calculators, Fitout Calculators and the VOC credit) in Green Star rating tools for design and construction, and the Green Cleaning credit in Green Star - Performance.
