BASIX

If you're building a new home, undertaking renovations of $50,000 or more, or installing a pool or spa of more than 40,000 litres, you will need a BASIX certificate.

BASIX is one of Australia’s strongest sustainable planning measures. Use the  online BASIX assessment tool to assess the energy and water use and thermal comfort of your residential development.

On 17 November 2021, the NSW Government announced an increase in BASIX standards – see here. Additionally, we have released  a new beta version of the BASIX Tool for testing, – see here.
