Commercial Energy Efficiency

12 March 2018

The consultation period for commercial energy efficiency changes proposed in the National Construction Code (NCC) 2019 is open and the ABCB is seeking your feedback.

Previously the Australian Building Codes Board (ABCB) communicated that feedback was sought on four Consultation Regulation Impact Statements (RIS’). Whilst the accessible adult change facilities in public buildings, fire safety in Class 2 and Class 3 residential buildings and heating and cooling load limits in residential buildings RIS’ are currently open for comment, the ABCB has now released the fourth Consultation RIS, energy efficiency of commercial buildings, for public comment.

The energy efficiency of commercial buildings Consultation RIS assesses the impact of proposed stringency changes to the energy efficiency provisions of Section J for NCC 2019 Volume One. This Consultation RIS is accompanied by an Energy Action report that models the impact of the proposed changes across four different building types in all climate zones.

What this means for comment on the commercial energy efficiency provisions

As a result of the delayed release of this Consultation RIS, the Public Comment Draft for Section J, NCC 2019 Volume One has been extended until Friday, 20 April 2018 to correspond with the public comment period for the Consultation RIS.

This Consultation RIS, the supporting Energy Action report along with the NCC 2019 Public Comment Draft can be download from the ABCB Resource Library.
