Design and construction of fitouts
Green Star – Interiors rates the sustainable design and construction of any building fitout works. The Interiors rating tool aims to assist clients and project teams to objectively rate their projects, and achieve sustainability goals.
The tool provides a framework with clear guidelines to assist in designing and constructing a sustainable fitout. It encourages a new approach to designing and constructing fitouts by rewarding sustainability best practice and excellence. It also provides consistent and clear advice in an easy-to-use manner.

Green Star - Interiors
Certifications to date
Since the release of Green Star - Interiors in 2014, over 350 projects have been certified.
Green Star – Interiors superseded Green Star – Office Interiors, enabling ratings for a more diverse suite of fitouts to be rated. The uptake of projects certifying with Green Star – Interiors has been considerably more rapid than the prior rating tool.
Organisations with an interest in providing great places to work for their employees, and a great experience for customers and clients have been key users. Unlike other Green Star rating tools, where the use is often driven by external factors such as ESG reporting requirements and investor pressures, the use of Green Star – Interiors is generally driven from within the organisation.
The most frequent users of the tool include:
- Commercial corporates fitting out office workplaces
- Commercial retailers (generally adopting a volume approach) fitting out retail space e.g., bank branches, fashion stores, food retailers in food courts
- Education and industrial sectors
