The Evidence of Suitability method using the Deemed to Satisfy Provisions of Part J of the Energy Efficiency section of the NCC Volume 1 (formally the BCA) have been chosen as the most appropriate method to assess the compliance of the proposed development.

In response to growing concerns around greenhouse emissions, the Australian Government introduced a coordinated national approach in July 2000.

This approach focused on two key directions.

First, mandatory minimum energy performance requirements were implemented through the Building Code of Australia (BCA), ensuring all new buildings meet a baseline standard.

Second, the industry was encouraged to adopt voluntary best practice initiatives, allowing for innovation and higher performance outcomes beyond compliance.

These measures were supported by theNational Framework for Energy Efficiency(NFEE), a national agreement between Australian governments aimed at improving energy efficiency across the country. The objective was clear: unlock economic value through smarter energy use, while delivering cost-effective outcomes.

To support this transition, working groups were formed across government, industry, and community sectors. Their role was to contribute to the development of the BCA Energy Efficiency Provisions.

Recognising the impact of buildings on national emissions, theAustralian Building Codes Board(ABCB) and theAustralian Greenhouse Officeformalised their collaboration through a Memorandum of Understanding.

This led to the development of the Energy Efficiency Provisions now known asSection J of the National Construction Code (NCC)— applying to both commercial and residential buildings across Australia.
