With growing concerns for enhancing sustainability, much attention has being paid to benchmarking performance in buildings. This paper evaluates the effectiveness of three rating systems that have been widely adopted for over a decade in Australia namely: (i) mandatory compliance under Section J (Energy Efficiency provisions) in the National Construction Code of Australia (NCC), (ii) a voluntary design rating tool - Green Star, and (iii) a voluntary operational rating tool-National Australian Building Environmental Rating Scheme (NABERS). The paper builds on the authors’ experience in building performance simulation, rating tool design, practice consultancy and post occupancy evaluations of buildings. It presents a detailed analysis of the rating tools with respect to the alignment between what is being assessed, how it is assessed and administered and the impact on design process and performance outcomes in buildings. The paper assesses the successes and shortcomings of the rating tools to demonstrate the potential for design and post occupancy rating tools to influence market behaviour and building performance and argues for increasingly stringent approaches to get to net zero emissions.
