BASIX is a flexible tool which allows the user to select from a range of options in order to meet the energy and water reduction targets.
Each development application for a residential dwelling must be submitted with a BASIX certificate. A certificate is issued once a BASIX assessment has been satisfactorily completed, using the on-line tool.
The building applicant (e.g. architect, builder, owner builder) is responsible for completing the assessment, ensuring the BASIX commitments are clearly marked on the plans, and submitting the BASIX certificate with the development application.
