Everything You Need to Know About BASIX
New South Wales Government launched BASIX (The Building Sustainability Index) in 2004. The initiative was implemented to encourage eco-friendly, energy-efficient, sustainable residential developments. The BASIX compliance is a component of the Environmental Planning and Assessment Act. The climate crisis has become a grave concern globally. The BASIX certificate empowers NSW to build more resilient residential buildings by limiting greenhouse gas emissions and potable water consumption.
BASIX targets include:
- Up to 40% reductions in potable water consumption
- Up to 25% decrease in carbon footprints.
Therefore BASIX compliant projects can offer financial savings and clean living solutions to the residents.

What Does a BASIX Report Include?
A BASIX report contains all the information about your residential development. You’ll receive the BASIX certificate upon successful completion and submission of the report.
The BASIX Report includes:
- The geographical location of your project.
- Size of your development
- Orientation of the residential dwelling
- Category of construction of the building
- Window size and type used in the building
- Surrounding landscaping of the residential development
- Appliances used within the residential dwelling.
- Thermal comfort levels and heating and cooling requirements
How to Achieve a BASIX Compliant Residental Building Design?
To obtain your BASIX certificate, you need to consider various factors and make your project design sustainable. We’ve curated a few tips that will assist you to achieve the BASIX compliance standards.
Design with Correct Size and Eliminate Non-Functional Areas
Compact designs enable you to implement sustainable standards. Compact designs require less operational energy expenditure, and therefore reduced environmental impact.
- Keep in mind the area of the rooms and other utility spaces while conceptualizing the design.
- Australia boasts the most prominent residential buildings and houses in the world. Use smart, innovative designs to build your world-class residential developments.
- Limit non-functional areas. Non-functional areas can’t be used by residents and can contribute to more energy consumption. Therefore, eliminate such areas wherever possible.
Your residential projects will not be just BASIX compliant but can also achieve a great NABERS Rating.
Implement Passive Design Concepts
The passive design incorporates eco-friendly techniques to take advantage of your climatic condition and building orientation for minimal heating or cooling requirements.
Examples of passive designs include:
- Incorporating shaded areas.
- Accurate window orientation to enhance airflow and cool breezes,
- Allowing sunlight exposure during winter.
All these passive design features contribute to lesser dependency on mechanical heating and cooling- fewer costs for the residents, a more environmentally-friendly concept, greater demand, and market value for your project.
Most importantly, easier to obtain your BASIX certificate.
Consider the Climatic Conditions
Factoring the climatic condition of your residential project will have a minimal environmental impact and offer operational savings in the future.
The climatic zones of the Australian subcontinent range from tropical to alpine. Smart, simple design concepts aligning with the existing climatic condition can make a substantial difference in comfort.
Residential buildings developed in the cooler climates should be orientated to maximize midwinter sun exposure and include thermal mass materials (such as concrete) to capture the heat during the cold season.
In hot and dry or tropical climatic zones, design concepts must reduce sunlight heat transmission in the living space and maximize ventilation provisions throughout the dwelling.
The BASIX certificate considers climatic zones for specifying energy standards.
Install the Correct Windows
The windows and glazed doors’ quality, size, and orientation greatly impact your building’s sustainability and environmental consequence.
Despite having accurate insulation concepts, certain types of windows and glazing can allow large volumes of heat to enter and escape the interior living space.
Some easy tips to improve your windows are to choose double glazing to ensure reduced heat transmission.
Opt for Energy Efficient Appliances
The choices you make for the appliances within the residential dwelling can affect the overall sustainability of your building.
Inefficient, high energy consuming appliances just don’t increase the residential energy expenditure. They may also generate excess heat, which is a concern for hot climatic zones.
Also, it’ll undo your efforts to align your project with eco-friendly standards through smart design concepts. This can cause a significant complexity in obtaining your BASIX certificate.
Incorporate Water Efficient Designing Concepts
BASIX aims to reduce water consumption as well. Therefore you need to incorporate concepts that minimize water wastage and promote efficient usage.
- Consider incorporating rainwater harvesting systems.
- Installing dual toilets can reduce substantial footprints.
- Install showerheads.
- Ensure to utilize efficient water pipelines and quality tap will aerators to reduce leakage and allow water flow control.
- Consider including a gas-based hot water system with a storage tank. Such systems generate much fewer carbon footprints compared to continuous flow systems.
BASIX is beyond a legal requirement. It contributes to the well-being of the environment and the residents. Get your project BASIX certified with the help of experienced building consultants.
