Residential Sustainability Certification
A clear guide to the Green Star Homes certification pathway for eligible volume home builders in Australia.
Understand how product ranges are assessed against Positive, Healthy and Resilient outcomes, from Green Star Designed assessment through to certification of completed new homes.
Explore the Certification PathwayIn Brief
Green Star Homes is a voluntary residential certification pathway developed by the Green Building Council of Australia for eligible volume home builders. It provides a structured way to design, document and deliver new homes against defined Positive, Healthy and Resilient outcomes.
The pathway begins with assessment of a builder’s home designs or product range through Green Star Designed. Individual homes constructed from an assessed range can then progress toward formal certification using project-specific, as-constructed evidence.
Green Star Homes may draw on technical information relating to thermal performance, operational energy, electrification, indoor environmental quality, water, materials and climate resilience. These disciplines remain supporting inputs; Green Star Homes is the overarching certification framework that brings the required evidence together.
Eligibility
The current pathway is designed for eligible volume home builders assessing repeatable new-home designs or product ranges, rather than individual bespoke homes.
Assessment Pathway
A home design or product range is assessed first, followed by evidence from completed homes to demonstrate that the certified design intent has been delivered in construction.
Certification Outcomes
Green Star Homes organises its requirements around Positive, Healthy and Resilient outcomes for the design, construction and future operation of new homes.

Eligibility and Project Scope
Green Star Homes is currently designed for eligible volume home builders seeking to assess repeatable new-home designs or residential product ranges. It is not a general certification pathway for every individual house project.
Eligible Applicant
The pathway is intended for builders delivering new homes through established residential product ranges, supported by repeatable design, specification and construction processes.
Assessment Basis
Green Star Homes is structured around home designs that can be assessed consistently and then delivered across multiple sites using controlled plans, specifications and evidence pathways.
Outside Current Scope
One-off custom homes and individual homeowner projects are not currently the primary Green Star Homes pathway. Other residential performance or certification routes may be more appropriate.
Early Scope Review
Eligibility should be confirmed before detailed documentation begins. The builder structure, product-range model, certification objective and intended evidence process all influence whether Green Star Homes is the appropriate pathway.
Certification Outcomes
Green Star Homes organises its requirements around three connected outcome areas. Together, they provide the structure for assessing how a new home addresses operational impact, occupant wellbeing and long-term resilience.
Outcome One
Positive homes are designed to be highly efficient, fossil fuel free and powered by renewable energy, reducing the operational impact of the completed dwelling.
The certification pathway may draw on thermal assessments, energy modelling, appliance and hot-water specifications, airtightness information and evidence of renewable electricity supply.
Outcome Two
Healthy homes consider indoor conditions that support occupant comfort and wellbeing throughout normal residential use.
Relevant evidence may address indoor air quality, ventilation, moisture management, thermal comfort, daylight and the selection of products and materials used within the home.
Outcome Three
Resilient homes are planned to respond more effectively to climate conditions, resource constraints and future environmental pressures.
This may include water efficiency, preparation for extreme heat, consideration of natural hazards and design decisions that support the home’s durability and adaptability over time.
These outcome areas do not replace specialist assessments such as NatHERS, Whole of Home or water and materials documentation. Instead, Green Star Homes brings the required technical inputs together within one residential certification pathway.
Design-Stage Assessment
The Green Star Designed assessment is the first formal stage in the Green Star Homes pathway. It allows an eligible builder to submit a standard home design or product range for assessment against the requirements of the Green Star Homes Standard.
The assessment establishes a documented design basis that can be used across eligible homes constructed from that range. It is not the final certification of an individual home; certification follows after construction and requires project-specific, as-constructed evidence.
Stage One
The builder identifies the standard designs or product ranges to be assessed and registers the pathway with the Green Building Council of Australia.
Stage Two
Plans, specifications, technical assessments and supporting documentation are coordinated to demonstrate how the proposed designs address the required Positive, Healthy and Resilient outcomes.
Stage Three
The submission is assessed by GBCA. Where the relevant requirements are met, the product range is awarded Green Star Designed recognition before individual homes progress to construction and certification.
Designed Is Not Final Certification
A Green Star Designed outcome confirms that the submitted product range has been assessed at design stage. The pathway is intended to continue through construction, with each completed home requiring its own evidence-based certification assessment.
As-Constructed Certification
After a product range has completed the Green Star Designed assessment, individual homes constructed from that range can progress toward certification. The completed home must demonstrate that the assessed design intent, specifications and required sustainability measures were delivered during construction.
Construction Delivery
The home is constructed using the approved design basis, relevant specifications and controlled product selections associated with the Green Star Designed product range.
Project Evidence
Project records are assembled to confirm the products, systems and construction outcomes delivered on the individual site. Evidence may include certificates, schedules, photographs, invoices and commissioning records.
Final Assessment
The as-constructed submission is assessed against the Green Star Homes requirements. Certification is awarded only when the required evidence demonstrates that the completed home satisfies the applicable outcomes.
Where the completed home satisfies the applicable requirements, it can receive Green Star Homes certification and use the associated Green Star Homes Trademark in accordance with GBCA requirements. This provides independent confirmation that the dwelling has completed the recognised certification pathway.
This second-stage review is important because a design-stage outcome does not, by itself, confirm how an individual dwelling was built. Construction substitutions, site conditions, product changes and incomplete records can all affect the final certification pathway.
Evidence Should Be Planned Early
The most reliable certification process begins before construction. Responsibilities for collecting records, approving substitutions and checking completed work should be built into the builder’s delivery and quality-assurance process from the outset.
Evidence and Documentation
Green Star Homes is assessed through documented evidence. The submission must show how the product range has been designed to meet the Green Star Homes requirements and how those requirements were delivered in each completed home seeking certification.
Some information can support the assessment of an entire product range, while other records must relate to the individual dwelling and its as-constructed condition. The exact documentation will depend on the applicable requirements, the home design and the evidence accepted by the Green Building Council of Australia.
Product Range Evidence
Evidence may include standard plans, schedules, specifications, approved design variations, product selections and documented controls for maintaining the assessed design across multiple locations.
Technical Evidence
Supporting information may include residential energy assessments, calculations, product data, glazing and insulation schedules, services information and specialist evidence addressing relevant certification requirements.
As-Constructed Evidence
The completed-home submission may require photographs, installation records, certificates, declarations, invoices, testing results or other records confirming what was installed and delivered on the individual site.
A Volume-Based Evidence Approach
Green Star Homes is structured to support certification at scale. Evidence that applies consistently across a product range may be assessed once, reducing unnecessary repetition across individual homes.
This makes document control important. Design variations, specification changes and construction substitutions should be reviewed before they are adopted so the certification basis remains clear and defensible.
Related Residential Pathways
Green Star Homes does not replace residential compliance assessments, energy ratings or specialist certification systems. It acts as an overarching voluntary framework that brings relevant technical evidence together around Positive, Healthy and Resilient outcomes.
Thermal Performance
NatHERS assesses the modelled thermal performance of the dwelling design. Its results may support Green Star Homes requirements, but NatHERS remains a separate residential energy-rating pathway.
Household Energy Systems
Whole of Home models household appliances, hot water, heating and cooling, solar generation and battery storage. It can provide supporting energy evidence without becoming the broader certification framework.
NSW Compliance
BASIX is a mandatory NSW planning and residential sustainability pathway. Green Star Homes is voluntary and broader in scope, although evidence prepared for BASIX may inform parts of the certification process.
Victorian Planning
BESS supports sustainability assessment for Victorian planning applications and specific developments. It is distinct from the national Green Star Homes pathway for eligible residential product ranges.
High-Performance Design
Passive House is a specialist performance and certification standard centred on fabric efficiency, airtightness, ventilation and comfort. It may suit individual high-performance projects outside the current Green Star Homes eligibility model.
Broader Green Star System
Other Green Star rating tools apply to buildings, fitouts, communities and operational assets. Green Star Homes is the residential pathway specifically structured around eligible new-home product ranges.
One Project May Involve Several Pathways
A Green Star Homes project may still require separate planning approvals, compliance certificates, energy ratings and specialist assessments. Early pathway mapping helps establish which documents can support more than one requirement while keeping each assessment’s purpose and evidence obligations clear.
Project Team Coordination
Green Star Homes requires coordination across design, technical assessment, procurement and construction. The pathway is easier to manage when certification requirements are translated into clear responsibilities before product ranges are finalised or homes begin construction.
The builder remains central to the process because repeatable design controls, approved specifications and consistent construction records must be maintained across the product range. Consultants, suppliers and delivery teams then contribute the specialist evidence required for their areas of responsibility.
Pathway Strategy
Confirm eligibility, identify the product ranges to be assessed and establish how the Positive, Healthy and Resilient requirements will be addressed before detailed evidence is prepared.
Technical Coordination
Residential energy assessments, services information, product data and other specialist inputs should align with the controlled plans and specifications used across the assessed product range.
Construction Delivery
Site teams, procurement staff and suppliers need clear processes for approving substitutions, recording installations and collecting the as-constructed evidence required for completed-home certification.
Consistency Across the Product Range
The value of a product-range pathway depends on consistent delivery. Uncontrolled specification changes or incomplete construction records can weaken the connection between the assessed design and the completed home.
A clear responsibility matrix, controlled document register and evidence collection process can help the builder maintain a reliable certification pathway across multiple designs, sites and construction teams.
Frequently Asked Questions
Green Star Homes is a voluntary residential certification pathway developed by the Green Building Council of Australia for eligible volume home builders. It assesses new-home designs and completed homes against defined Positive, Healthy and Resilient outcomes. Read What Is Green Star Homes in Australia?.
The current pathway is structured for eligible volume home builders delivering repeatable home designs or residential product ranges. The builder’s delivery model, design controls and ability to maintain consistent specifications across multiple homes are important parts of pathway eligibility.
The current Green Star Homes pathway is not generally intended for one-off custom homes or individual homeowner projects. Alternative residential performance or certification pathways may be more appropriate for bespoke new homes, renovations and existing dwellings.
Green Star Homes is administered and formally assessed by the Green Building Council of Australia. Consultants can support pathway planning, technical assessments, evidence coordination and submission preparation, but formal certification is awarded by GBCA.
No. Green Star Designed relates to the design-stage assessment of an eligible home design or product range. Individual homes constructed from that range must later provide project-specific, as-constructed evidence before they can receive final Green Star Homes certification.
No. Green Star Homes is specifically structured around eligible new-home product ranges and completed residential dwellings. Other Green Star rating tools apply to buildings, fitouts, communities and operational assets. Read Green Star Homes vs Commercial Green Star or visit the Commercial Green Star Knowledge Hub.
No. NatHERS assesses the modelled thermal performance of the dwelling design, while Whole of Home considers household energy systems, appliances and onsite generation. These assessments may provide supporting evidence within Green Star Homes but remain separate technical pathways.
No. Green Star Homes is voluntary and does not replace planning, building approval or residential compliance requirements. A NSW project may still require a BASIX assessment, while projects in other jurisdictions remain subject to their applicable state and territory requirements.
Green Star Homes is focused on eligible new homes delivered through a volume-builder product range. Existing-home assessments, renovation advice and upgrade planning sit within separate residential performance pathways.
Planning should begin while the product range, standard specifications and delivery procedures are still being developed. Early coordination allows certification requirements to be incorporated into design controls, procurement decisions, construction processes and evidence collection before changes become difficult to manage.
Certified Energy can help review pathway suitability, coordinate residential performance inputs, prepare relevant technical assessments and organise evidence requirements across the design and construction stages. The required scope will depend on the builder’s product range, delivery systems and intended certification strategy.
