BASIX

BASIX is an online program that is accessible to anyone. The user (usually the building designer) enters data relating to the house or unit design – such as location, size, building materials, method of cooling and heating etc – into the BASIX tool. BASIX analyses this data and determines how it scores against the Energy and Water Targets. The same targets are in place across all NSW Council areas.

The design must pass specific targets (which vary according to location and building type) before the user can print the BASIX Certificate.

The commitments made during the BASIX process are shown the final certificate and must be marked on the plans, and adhered to during the building process.

BASIX is administered by the NSW Government. Council does not make or control the requirements of BASIX.

Council's role with BASIX is to ensure that a Certificate is lodged with each Development Application where relevant, and check that that all BASIX commitments are adhered to at each stage of construction.

BASIX applies to:

• New residential dwellings with a total cost of $50,000 or more.
• Alterations or additions to existing residential dwellings with a total cost of $50,000 or more.
• Swimming pools with a capacity greater than 40,000 litres.

If your proposal falls into of the above three categories, then you will need to submit a BASIX Certificate with your Development Application or application for a Complying Development Certificate.

Note – If your dwelling is a 'manufactured home' or 'moveable dwelling' then the requirements of BASIX will not apply. If you require further clarification in relation to 'manufactured homes' or 'moveable dwellings' contact the BASIX helpline on 1300 650 908 between 2pm – 5pm Mon – Fri.

You can obtain a BASIX Certificate yourself or you can ask your building designer to obtain it on your behalf. Following the steps below:

• Go to the BASIX website and login to the BASIX assessment tool.
• Complete the assessment form by entering the design details of your home. The tool demonstrates how your proposed design is scoring, according to its potential to save energy and water.
• Once your design meets the target, you can print your BASIX Certificate.
• Lodge your proposal at Council with your BASIX Certificate.

BASIX is a flexible tool that offers a range of design choices using:

• Insulation
• Window glazing
• Eaves and window shading
• Wastewater for garden use
• Light coloured roof materials
• Gas or solar hot water systems
• Skylights to bring in natural light
• Landscaping that requires less water
• Rainwater tanks for use in gardens, toilet and laundry
• Water-saving showerheads, taps and dual-flush toilets
• Passive solar design to make your home warmer in winter and cooler in summer

Further information on the requirements of BASIX can be found on the BASIX website.

 The NSW Government has also established a BASIX helpline – 1300 650 908.
