Changes to the NSW BASIX Scheme

Changes to the NSW BASIX scheme

The NSW Government has committed to achieving net zero emissions by 2050 to help improve the quality of life for the people of NSW to protect the environment and maintain a strong economy, which means reducing energy consumption in measurable ways.

What are the changes to the BASIX scheme?

  • A minimum standard of compliance with the Building Code of Australia’s energy efficiency requirements is being increased from 6 stars to 7 stars (out of 10).
  • Energy consumption stringency increased, varying with building location and type.
  • There will also be a new provision introduced to calculate and report the embodied emissions of building materials in the building. There is no specific target or benchmark, but information must be reported on the embodied emissions through a new calculator.

The key changes that will impact new builds are:

  • R6.0 Bulk Insulation to all trussed ceilings (excl. Outdoor Areas)
  • Double Glazed Low-e Clear to all windows/sliding doors (excl. Bedrooms & Wet Areas)
  • R2.5 HD Insulation to all external walls including Garage internal walls
  • Use of light roof colours
  • Thermal wall wrap to all external walls

Please note that the key changes noted above is an estimate of the products the homes may need to meet the BASIX requirement. These inclusions are subject to change without notice and will be determined once the BASIX assessment has been completed on the home. Modifications

What will this result in?

  • Cheaper energy bills. You’ll use less electricity so your bills will be cheaper – saving as much as $980 a year on energy bills, according to a NSW Government website
  • More comfortable homes. Your home will be naturally cooler in summer, warmer in winter, which means you won’t be turning the heater or air conditioner on as often.
  • Fewer carbon emissions. This contributes towards our goal of net zero homes by 2050.

How will the changes impact my ZAC Homes project?

You can expect additional costs due to the building components required to meet the standards. These costs will vary depending on the home design, climate zone and location, it will also include other factors like neighbour shading and proximity to other buildings.

How do I beat the BASIX price rise?

If you have yet to engage in the building process with us, you must start the process as soon as possible to ensure your CDC or DA application is lodged and accepted on the Planning Portal with a valid BASIX certificate prior to 1st October 2023.

We have just started our building journey with ZAC homes. We have chosen to build with ZAC homes as they have allowed flexibility with the design, resulting in a better usage of the living and bedroom spaces. Other companies had a rigid design which would have resulted in variation fees.


…ZAC Homes kept us regularly up to date with the progress of our home and the job was finished on time, which was very important to us. We are one hundred percent happy with our home and can thoroughly recommend ZAC Homes and their crew to anyone contemplating building a home.

…Firstly I would like to thank the ZAC homes team for the experience that my wife and I have had when making the purchase of an investment property. The professionalism and dedication that was displayed, was by far the best that we have seen or experienced previously.

I can not speak more highly of this local building company. Right from the beginning they have been excellent to deal with…The finishes were very good and any work that I wanted fixed which was minor things was done


Very well managed with no hidden cost or surprises. Workmanship was excellent and very professional


Really pleased with the building process, communication and designs. Would definitely recommend.

The customer service and assistance was superb with quick turn around times and patience with our queries. Everything from initial consultation, to colour selection to hand-over was organised easily and open communication was maintained throughout the process.
