Achieving deep-energy retrofits for households in energy poverty

Climate change and energy poverty are two sustainability challenges that can be addressed through deep-energy retrofits for homes. This systematic review identifies which factors influence the achievement of energy retrofits for households vulnerable to energy poverty. It covers both energy-poor households and the landlords or building owners of energy-poor households. The results identify a range of influential factors across several themes: financial, policy and organizational, trust and communication, technical, attitudes and values, and health. Health and quality of life are particularly influential motivating factors among households vulnerable to energy poverty, as is the presence of trust and communication between stakeholders. Multiple financial considerations are also important, such as the availability of no-cost retrofit options and the prospect of lower energy and maintenance costs. Lastly, government requirements to retrofit and minimum energy standards are motivating, particularly in the social housing sector. These findings and the lack of focus on energy poverty within the energy retrofit literature and policies point to a need for further research on this topic, and for retrofit policies specifically targeted to households vulnerable to energy poverty.
