NSW 2 Energy efficiency
In NSW, Class 1 and 2 buildings, Class 4 parts of buildings, and certain Class 10 buildings are subject to BASIX (the Building Sustainability Index), the web-based planning tool designed to assess the potential performance of these buildings against a range of sustainability indices including thermal comfort and energy. Commitments made under BASIX become a condition of the relevant development consent or complying development certificate. BASIX applies to these types of new buildings in NSW; to alterations and additions to buildings of those classes where the work is subject to BASIX; and also where an applicant elects to comply with BASIX. The following provisions are therefore designed to complement requirements that arise under BASIX and which are implemented via the development consent.
Where BASIX is not applied to alterations and additions to these types of buildings, the provisions will also complement council development controls that require energy efficiency measures to be incorporated as part of the alterations and additions. For example: NSW Part 3.12.1 specifies installation requirements for, and the standards that must be met by, insulation required by any of the foregoing.
