The notional benefits of more efficient use and effective retrofit to existing housing is both sensible and attractive. Unlike new build, performance improvements cannot be pursued purely by legislation and regulation. Instead, householders need to be persuaded of the material benefits of better energy practices. In improving energy efficiency in the home, providing relevant and useful guidance is critical. Current guidance rarely takes account of specific cultural and ethnic circumstances. The research examines the relationship between cultural values and the energy use behaviour of diaspora households in the UK. The paper presents the results of two surveys that seek to measure energy use practices in the British Indian community. The first, conducted by the authors in England, seeks to understand attitudes and habits in relation to energy consumption in the home for British Indians. This is compared to a wider survey of British attitudes using an identical question set as undertaken by the EnerGAware project. The second survey researches cultural perspectives on the home in a British Indian community. This is compared to an identical survey conducted by the authors with comparative Indian households. The results of the research highlight where behavioural characteristics between the two contexts diverge. The paper suggests there are key areas for future research using ethnographic as well as quantitative techniques to produce tailored strategies for energy conservation in British Indian communities.
