Doctoral thesis of Philosophy: Residential energy efficiency and health – A mixed methods study of a quasi‐randomised controlled trial of energy efficiency improvements of the homes of low‐income Home and Community Care recipients near Melbourne, Australia

This thesis contributes to a better understanding of the relationship between residential energy efficiency and health. The thesis argues that residential energy efficiency improvements are complex interventions in complex socio‐technical systems. Informed by critical realism and the pragmatic pursuit of ‘what works’, the thesis suggests that the designs of residential energy efficiency improvements for health need to address the dynamic interactions between the physical quality of the building, the practices of householders in using the dwelling as a home, and contextual conditions to achieve optimal outcomes.
