Australian non-domestic buildings policy as an international exemplar

The Australian policy approach, based on the NABERS energy performance benchmarking scheme for commercial offices, is promoted as a 'success story' and is of interest to governments internationally. This paper explores the evidence for the impacts of the Australian approach on energy use and carbon emissions, identifies the key elements of its conception, design and implementation, and investigates the role of government. It uses a mixture of literature review, re-analysis of quantitative data and analysis of 30 original stakeholder interviews. The literature suggests that NABERS' appeal to multiple benefits of energy efficiency and its place in the wider policy mix should help deliver positive results. Analysis of publicly available data has highlighted data gaps. However, evidence suggests significant energy savings have been made, although the attribution to NABERS alone, given the policy mix, is uncertain. The interviews show high levels of agreement that the policy mix has transformed large commercial office buildings. They also highlight the wide range of actors mobilised to deliver this change and the central role of well-designed government intervention and support. The Australian experience is rightly of interest to international governments, but they must recognise that replicating its success requires attention to detail and long-term commitment.
