BASIX is a NSW Government tool that aims to encourage sustainable residential development. Considering energy and water efficiency when designing or renovating a home will not only ensure compliance with the State Government requirements, but can also lead to significant ongoing cost savings.
What is BASIX?
BASIX is short for Building Sustainability Index. It is a web-based planning tool designed to assess the potential performance of residential developments against a range of sustainability indicators.
People lodging certain residential development applications will be responsible for undertaking a BASIX assessment for each residential development proposal as part of the development approval process in NSW.
Since 1 July 2007, a BASIX certificate is required for all alterations and additions to existing dwellings where the estimated construction cost is more than $50,000.
BASIX also applies to new dwellings, semi-detached dwellings, multiple dwelling developments and boarding houses and swimming pools with a volume greater than 40,000 litre capacity.
An Accredited Certifier must not issue any Occupation Certificate unless it is satisfied that each of the BASIX commitments has been fulfilled.
Applicants can generate the BASIX Certificate and find further information via the Department of Planning’s BASIX website.
A Basix Self Certification Form is available and must be used on completion of a BASIX installation to verify to Council and the State Government that all BASIX commitments have been met.
