Green Star Homes is Australia’s leading rating tool for new homes.
Green Star Homes seeks to create highly efficient, fossil fuel free homes, powered by renewables that are healthy and resilient for all Australians. The Green Star Homes Certification provides you with the assurance from Australia’s leading authority on sustainable buildings with the Green Star Homes Trademark, which you can proudly display to your customers.
The Green Star Homes standard is created for volume home builders.
Released: 31 August 2021.
Green Star Homes has three categories focussing on core outcomes that define what a healthy, resilient and positive home is. Each category contains a number of credits with requirements that must be met to meet the Green Star Homes Standard.
A Positive home is one that is energy efficient and powered by renewables. This means it has been built to generate sufficient renewable energy to power estimated regulated loads as well as estimated appliances and plug loads. It does not use gas.
These requirements cover:
• Thermal Performance
• Window System
• Hot Water
• Energy Efficient Appliances
• Renewable Energy
• Home User Guide
A healthy home has been built to be well ventilated to prevent the growth of mould. It has also been built to minimise the entry of pollutants. It is thermally comfortable and uses materials that are low or non-toxic. High quality lighting has been installed.
These requirements cover:
• Air Quality
• Moisture Management
• Light Quality
• Material Toxicity
A resilient home is one that has been built to be better than Code at withstanding natural disasters and future climate change conditions such as bushfires, flooding, and extreme heat. The home also considers its effect on the broader climate by reducing water use and its impact on the community.
These requirements cover:
• Water Use
• Heat Resilience
• Resilience Essentials
Green Star homes is the only independent sustainable homes certification available in Australia.
By certifying your homes, you will receive the following benefits:
GBCA is working closely with its stakeholders and partners to further raise awareness of Green Star Homes in industry, government and with consumers. By Certifying your homes with Green Star Homes, you can contribute this exciting movement, and respond to the growing consumer demand.

There are two important steps in certifying a home. The first is the Designed assessment. This award entitles the builder to use the Green Star Designed logo is for marketing purposes associated with their standard design or product line prior to construction.
Once a home has been built, the builder will submit ‘as constructed’ evidence for assessment and certification. A Certified home can be marketed as being built to the Green Star Homes Standard.
Both stages are a document-based assessment process like that available under other Green Star rating tools. The documentation requirements work in a similar manner to other Green Star rating tools. Green Star Homes takes a ‘volume’ approach to certification. For example, evidence for many credits will be submitted and assessed once, rather than for each individual house seeking certification. Through this approach efficiencies in documentation can be made, thus allowing certification at scale.
The first step on your path to certification is the Green Star Designed assessment. This stage involves submitting the designs of your product range for assessment with GBCA. If it meets the Green Star Homes requirements it will be awarded as ‘Green Star designed’.
Once awarded by GBCA, this entitles you (the builder) to use the Green Star ‘Designed’ logo for marketing purposes on that product. This will indicate to consumers that the home design complies with Green Star Homes.
The ‘Designed’ assessment is not a formal certification. A standard design or product line is a pre-set design that a customer can purchase. They may be allowed set variations on this base design. These homes are not bespoke, thereby creating economies of scale through replication, streamlining, and enhancing efficiencies. This ‘Designed’ home could feasibly be built many times and across multiple locations, as it will form part of a builder’s product range that they offer their customers.
The second stage is Certification. This is a formal process by which the individual home is awarded a rating following an independent, third-party assessment of the project's submission against the requirements of the rating tool. This is what allows you to prove to your client that their house has been independently certified to meet Green Star Homes’ requirements,.
