The ever-increasing need for energy efficiency and sustainability adoption in the built environment is imperative to mitigate and minimize future challenges from climate change and limited finite resources. To meet these challenges, a transformative shift is required in how property owners and investors consider the importance of environmental performance, in particular, energy efficiency and engaging in a program of change.

This research investigated Australian new housing consumers awareness, comprehension, trust, and value in a rating which is mandatory for all new dwellings. The findings of the research highlights the large number of consumers unaware of their homes’ certification and low levels of awareness of the mandatory rating system per se. However, those consumers who were aware and familiar with the certification demonstrated a greater association with their willingness to pay and perceived value. Further, it was found that consumers’ familiarity and underlying attitude towards the certification program did affect their decision-making in the purchasing process and the way in which they use their homes. The results provide insights for governments’ policy development and housing industries strategies to promote energy efficiency and sustainability through rating systems. This research demonstrates a need for clear messaging and communication to increase awareness and engage consumers to make better housing choices and use their homes in a more efficient and sustainable way.
