Basix Report

Building Sustainability Index (BASIX) Report

BASIX was introduced to encourage sustainable residential development by New South Wales (NSW) Government. It aims to promote more residential dwellings by simultaneously reducing greenhouse gases and water consumption.


When Do You Require a BASIX Certificate?

You will require the BASIX Certificate if you intend to submit a development application to an NSW local Council to:

Construct a new residential dwelling like a single house, dual occupancy, townhouse or multi-unit.

Alter, enlarge or extend buildings with more than one dwelling (other than hotels or motels).

Undertake a development for the purpose of building a large swimming pool or spa.

Goals of BASIX Certification Programme

There are three basic goals involved in the introduction of BASIX Certificate Programme:

To reduce clean water consumption by 40%.

To reduce greenhouse gas emissions by 40%.

To set standards for the thermal performance of the home.

BASIX Assessment

The development application process undergoes Basix Assessment which measures your proposed development for sustainability against the set Basix targets. And, achieving the set standards further promotes a reduction in water and energy consumption in homes across NSW. The assessment is based on the following criteria:


Location of the building

Orientation size of the building

Construction type of the building

Window size and type of the building

Landscaping of the building

Appliances used within the building

Apart from this, it also considers thermal comfort levels which lessen the amount of energy used by dwellings in order to heat or cool the house to a comfortable level.
