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.

Green Star Homes is a voluntary residential certification pathway structured for eligible volume home builders. It brings energy performance, indoor-environment considerations and climate resilience together across repeatable home designs and individual completed dwellings.

Thermal comfort is influenced by the way the home responds to heat, cold, solar exposure, air movement and changing outdoor conditions. Orientation, glazing, shading, insulation, construction systems, air leakage, ventilation and household services can all contribute to that response.

This guide focuses on how those inputs support the Green Star Homes framework. It does not replace the separate technical territory of NatHERS thermal assessment, Passive House certification or specialist Thermal Comfort Modelling.

Green Star Homes is a voluntary Australian residential certification pathway developed by the Green Building Council of Australia. It is structured for eligible volume home builders delivering repeatable new-home designs or product ranges and organises its requirements around Positive, Healthy and Resilient outcomes.

Passive House is a separate international building-performance standard. It uses the Passive House Planning Package, known as PHPP, together with detailed envelope design, airtightness, high-performance windows, thermal-bridge control, controlled ventilation and project verification.

This comparison explains where the two pathways differ, where they overlap and when each may be relevant. For complete framework guidance, visit the Green Star Homes Knowledge Hub and the Passive House in Australia guide.

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.
