NSW Section J Energy efficiency
Replace Section J with NSW Section J as follows:
From 1 May 2019 to 30 April 2020 Section J of NCC 2016 Volume One Amendment 1 can be used instead of Section J of NCC 2019. From 1 May 2020 Section J of NCC 2019 applies.
NSW Section J consists of two Subsections J(A) and J(B).
NSW Subsection J(A) Energy Efficiency - Class 2 buildings and Class 4 parts
This Subsection contains energy efficiency requirements for Class 2 buildings and Class 4 parts of buildings.
The need for separating these requirements from the requirements for Class 3 buildings arises because, in NSW, Class 2 buildings and Class 4 parts of buildings are subject to BASIX (the Building Sustainability Index), however Class 3 buildings are not.
BASIX is the web-based planning tool designed to assess the potential performance of certain residential 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 in NSW to all new Class 1 and 2 buildings, and Class 4 parts of buildings; and 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 provisions of NSW Subsection J(A) 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 Class 1 and 2 buildings, and Class 4 parts of buildings, these provisions will also complement council development controls that require energy efficiency measures to be incorporated as part of the alterations and additions.
NSW Subsection J(B) Energy Efficiency - Class 3 and Class 5 to 9 buildings
This subsection contains energy efficiency requirements for Class 3 and Class 5 to 9 buildings.
As Class 3 and Class 5 to 9 buildings are not subject to BASIX, NSW Subsection J(B) applies the provisions of the national Section J relevant to Class 3 and Class 5 to 9 buildings, with minor variations.
All definitions in Schedule 3 that are applicable to the national Section J are also applicable to NSW Section J.
