What is BASIX

Introduced by the NSW Government, BASIX®, the Building Sustainability Index, 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 dwellings and units.
BASIX is a NSW Government web-based planning tool that assesses the water and energy efficiency of new residential buildings. 

A BASIX certificate is currently required for all new development and complying development applications associated with new residential buildings, such as:

  • Single dwellings

  • Dual occupancy dwellings

  • Villas

  • Townhouses

  • Unit & Multi unit developments

  • Alterations & additions greater or equal to $50,000

  • Swimming pools and/or outdoor spas with a water capacity greater or equal to 40,000 Litres

Attaining a BASIX certificate means that a new residential building has passed the Government's target to reduce water and energy use in your home. This means you also save money on your water and energy bills. 

BASIXMAX can provide you with a BASIX certificate listing the BASIX requirements for all Development Applications.
