The ‘Beat The Heat!’ project was a project of the Australian Federal Government’s ‘Low Income Energy Efficiency Program’ (LIEEP). This project aimed to enhance the resilience and improve the comfort and well-being of Adelaide households during South Australia’s long, hot summers. The installation of ceiling insulation and new air-conditioners in the main living areas of low-income households were two of the key interventions made through this project. Total electrical energy consumption of each household and the air-conditioner were monitored following these interventions and compared with electricity bills before the installation, during matched summer periods. Indoor temperatures of the main living area were also monitored, following the intervention, to assess the improvement in thermal comfort. Significant differences between the energy use before and after household interventions, along with associated household perceptions, are discussed in this paper. Specifically, the impact on energy consumption of factors such as household income, the source of cooling energy prior to the intervention and differences in climate and thermal comfort are explored.
