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 29 August 2022, the NSW government announced increases to the BASIX standards, as part of the new Sustainable Buildings State Environmental Planning Policy (SEPP) which will come into effect on 1 October 2023.
The beta BASIX sandbox tool is available to test your designs against the higher standards.
The BASIX tool is moving
The BASIX tool is being enhanced and is moving to the NSW Planning Portal in mid-2023. You will need a Planning Portal account to access the enhanced BASIX tool. For most BASIX users, we will create a Planning Portal account (if you do not already have one) and transfer your projects to the portal. Other types of BASIX accounts will need to set up their own Planning Portal account.
