If your design cannot be assessed by the BASIX assessment tool you may be eligible to apply for an Alternative Assessment.
What types of proposals may need an alternative assessment?
The alternative assessment will be appropriate where the proposed development:
- is of a type which cannot be characterised by the BASIX assessment tool
- is subject to specific heritage controls which conflict with the BASIX requirements
- includes new technology
- includes water and energy saving measures which are not reflected in the BASIX tool
- Make an application for an alternative assessment through the application form on the Alternative assessment page in the BASIX tool.
- Ensure that the project is complete in the BASIX tool, leaving only the selections relevant to the alternative assessment as 'please select' or 'no system'.
- Submit the application form describing why alternative assessment is required in relation to the government' water and energy targets. Ensure sufficient details are provided to allow for the application to be assessed.
- The Department of Planning & Environment makes an initial assessment of the application and will contact the applicant within 3 working days.
- If an alternative assessment is appropriate for the development proposal, the Department will provide the applicant with more information and assessment criteria to describe and justify the water and energy reduction of the new technology or solution.
If your application has been accepted, there is an approximate turn-around time of at least 20 working days from the date of the application and an additional cost will apply.
