Energy efficient behavioural trends in residential sectors for low-income cultural background: A case-study of slums in Chittagong, Bangladesh

Slums may be a by-product of the urbanization process in a developing country like Bangladesh. The slum dwellers' lack of energy awareness is the primary impediment to domestic energy savings. In countries such as Bangladesh, where wages are extremely low, energy awareness is primarily focused on behavioural issues. This study presents the results of an energy awareness feedback program on the energyefficient behaviours of various groups of slum occupants in Chittagong, Bangladesh. All slum occupants are classified here according to their housing structure and economic circumstances. Initially, occupants are informed about the various solutions and opportunities for energy conservation through low- or no-cost measures. Following that, a survey was conducted (between May and June 2020) in 54 individual houses (similar in size but with varying housing structures and economic conditions) in slum areas to ascertain the impact of efficient energy behaviour on lighting and appliances. A statistical analysis (two-way ANOVA) was conducted to determine the efficient energy behaviour trends associated with the selected housing groups' structure and economic conditions. The study will aid in the implementation of several actions aimed at addressing various energy-efficiency issues affecting lowincome communities in Bangladesh.
