What is a BASIX Certificate?

In simple terms, a BASIX certificate is a document. It proves your new development meets the minimum standards for sustainability set by the NSW government. It demonstrates that your home is designed to

• use less water and
• create fewer greenhouse gas emissions.

It focuses on three main areas:

Water Efficiency

To attain water efficiency, you need to reduce your reliance on potable water. This can be done through

• rainwater tanks,
• water-saving fixtures, and
• efficient landscaping.

This is similar to NABERS water rating for office buildings.

Thermal Comfort

In the thermal comfort section, you need to ensure you need minimal energy to keep your home

• cool in summer and
• warm in winter.

This involves factors like

• insulation,
• window placement, and
• shading.

Energy Efficiency

To attain energy efficiency for BASIX, you need to minimise your home’s energy consumption. You need to focus on the following areas:

• lighting,
• appliances, and
• heating/cooling.

This is achieved through energy-efficient design and technologies. Only when you fulfill the requirements in these three section you can obtain a BASIX certificate.

Who Needs a BASIX Certificate?

A BASIX Certificate is mandatory for most residential building projects in NSW. This includes:

• Constructing a new house, townhouse, or apartment
