As of 1 April 2023, the requirement to use an approved sustainable building rating tool applies to the construction of all new government owned non-residential building with an estimated capital value of $9 million and over.
This is the second stage of changes to the Procurement guide to reducing carbon emissions in building and construction. The first stage of this requirement, to buildings in scope with a capital value of $25 million and over, applied from 1 April 2022. The initiative is part of The Carbon Neutral Government Programme, a long-term work programme that aims to make a number of government organisations carbon neutral by 2025.
Sustainable building rating systems consider a broad range of environmental and social factors and provide a benchmark against which a buildings sustainability performance can be considered. They encourage a targeted focus on key areas, such as reducing embodied and operational carbon, and consistent application of processes to support achieving sustainable outcomes.
