Introduced by the NSW Government, the Building Sustainability Index (BASIX), ensures homes are designed to use less potable water and be responsible for fewer greenhouse gas emissions by setting energy and water reduction targets for house and units.
The tool helps you determine how to meet these targets from a wide range of options such as rainwater tanks, water-saving fixtures, improved insulation, passive solar orientation, natural lighting and native plants for gardens.
How Does BASIX Work?
BASIX is an online program that is free and accessible to anyone. The user (usually the building designer) enters data relating to the house or unit design - such as location, size and building materials into the BASIX tool. BASIX analyses this data and determines how it scores against the energy and water targets.
The design must pass specific targets (which vary according to location and building type) before the user can print the BASIX Certificate.
Recycled Water and BASIX
Hunter Water has two residential recycled water schemes that can be used in the BASIX assessment, please refer to the following plans to determine if your property is in these schemes:
The BASIX Certificate
This lists all the commitments the user has agreed to, and the Certifying Authority will check these at various stages of construction.
The BASIX Certificate must be attached to the development application before it can be processed.
Help is available on the Help Line: 1300 650 908 or via the BASIX website.
