NSW Building Sustainability Index (BASIX)
Introduced as part of the NSW planning system, BASIX - the Building Sustainability
Index - is a web-based planning tool that measures the potential performance of new
residential dwellings against the environmental criteria of energy, water and thermal
comfort.
Each development application for a residential dwelling in NSW must be submitted with
a BASIX Certificate. This Certificate will be required to show how your development
meets the BASIX targets for the Thermal Comfort, Energy, and Water
components of the BASIX regulation. This is completed on-line using the web based
BASIX tool. For more information see the BASIX website.
ABSA Assessors have been Accredited to carry out computer Simulation ratings and provide
Certification to show compliance with the Thermal Comfort - Simulation Method section
of BASIX. It is a mandatory requirement that an ABSA Assessor must be engaged to carry
out this work.
ABSA has extensive accreditation and Quality Assurance procedures for assessors, to
ensure that consumers and regulators can be confident in receiving a high standard
of professional service. Assessors are also backed by professional indemnity insurance.
You can loacte an Assessor using the Find
an Assessor page and selecting the 'Thermal Comfort Simulation (BASIX)' service.
NSW ABSA Assessors with particular expertise in sustainable building design can provide
advice and assist in preparing a BASIX Certificate. There is currently no formal accreditation
scheme for conducting BASIX assessments and issuing BASIX certificates.
You can search for Assessors who are able to prepare complete BASIX Certificates under Find
an Assessor and selecting the 'NSW BASIX Assessment' service. Before an Assessor
can be listed as being able to conduct BASIX assessments, ABSA requires the Assessor
to demonstrate:
-
industry experience and professional or trade qualifications
-
experience and competency in the nominated field
