What is a BASIX Certificate?

BASIX is short for Building Sustainability Index. The BASIX Certificate ensures that the design of your new home, structure or addition meets sustainability criteria as set out by the NSW Government. It was introduced in 2004 as a method of encouraging homes to be more energy and water efficient.

A BASIX Certificate usually costs $50, the NSW Government has agreed to waive this fee for bona fide bushfire rebuilds. You will need to call BASIX to access this benefit.

Do I need one?

If you are going to submit a development application to Council for a new home, you will need to include a BASIX Certificate with this application. This only applies to all new applications for residential building works valued at over $50,000.

What are the sustainability criteria?

BASIX takes into account the following three key criteria:

  • Water use
  • Energy consumption
  • Thermal comfort

It does this to determine the best methods, materials and inclusions that will enable a building to fulfil an energy efficiency rating. BASIX takes into account features such as building orientation, glazing, insulation, star rated taps and rainwater collection, which help to achieve efficiency targets.

What are the water and energy efficiency targets?

Water and energy efficiency targets are determined based on where you live. It takes into account regional variations such as climate as well as building type, aspect and location of the building.
