Green Star Homes is a voluntary residential certification pathway structured for eligible volume home builders. Its requirements bring energy, health and resilience measures together across repeatable home designs and individual completed dwellings.

Within that framework, water efficiency is not established by one isolated product. It depends on the relationship between water-using fixtures, appliances, outdoor demand, any alternative water supply and the specifications ultimately delivered during construction.

This guide focuses on water efficiency as a Green Star Homes framework and evidence issue. Broader residential compliance, site-water and stormwater pathways remain separate. For the complete certification context, visit the Green Star Homes Knowledge Hub.

An all-electric home uses electricity rather than gas or another onsite fossil fuel for major household services such as cooking, hot water, space heating and cooling. These systems can then be supported by onsite solar generation and renewable electricity.

Within Green Star Homes, this is not treated as a collection of unrelated appliance choices. The Positive outcome connects electrification with thermal performance, airtightness, efficient household systems, renewable energy and information that helps the resident operate the home as intended.

This guide focuses on how all-electric design is coordinated across an eligible volume builder’s product range and carried into individual completed homes. For the complete framework context, visit the Green Star Homes Knowledge Hub.

A stormwater treatment assessment considers how runoff from roofs, driveways, paving and other impervious areas is managed by the treatment measures connected to them. The presence of a tank, raingarden or permeable surface does not by itself establish that the required treatment outcome will be achieved.

Performance depends on the relationship between catchment area, treatment capacity, rainwater reuse, physical connections and any impervious surfaces that remain untreated. A measure that is appropriately sized and connected can contribute strongly to the assessment. The same measure may contribute much less where it receives only a small catchment or cannot operate as represented in the model.

This guide focuses specifically on how common WSUD measures can support quantitative stormwater treatment performance. For the wider difference between site strategy and modelling, see STORM vs WSUD.

Green Star Homes is a voluntary residential certification pathway developed by the Green Building Council of Australia. It is currently structured for eligible volume home builders delivering repeatable new-home designs or product ranges.

The phrase commercial Green Star is different. It is not the formal name of one rating tool. It is commonly used as shorthand for Green Star pathways applying to new buildings, major refurbishments, existing operational assets, fitouts and masterplanned communities.

This guide explains how the pathways divide the territory and why the correct tool depends on the project’s assessment boundary rather than whether the development is described informally as residential or commercial. For full framework guidance, visit the Green Star Homes Knowledge Hub and the Commercial Green Star Knowledge Hub.

BASIX is a New South Wales residential sustainability assessment used within the planning and development approval pathway. Where it applies, the project must complete the relevant assessment and carry the resulting certificate commitments into the design and construction documentation.

Green Star Homes is a separate voluntary certification framework administered by the Green Building Council of Australia. It is structured for eligible volume home builders delivering repeatable home designs or residential product ranges.

A NSW home may therefore require BASIX regardless of whether Green Star Homes certification is being pursued. The two pathways can be coordinated, but neither replaces the other. For full pathway guidance, visit the Green Star Homes Knowledge Hub and the BASIX assessment page.
