Drawing from film studies, this paper introduces a new, experimental method to understand domestic practices and energy use at home at the exploratory research phase. The paper adopts the methodology of the AHRC CineMuseSpace project and applies it in the context of energy studies. A detailed keyword ontology was developed in order to identify practices, technologies and energy use at home (854 keywords). 19 Indian films, based in chawl housing in Mumbai, were analysed to illustrate the method. The keyword ontology was were applied to the extracted film fragments in the database. This allowed to map the presence and use of technologies in film, and where and how practices were performed. The analysis was followed by site observations guided by the film analysis, and re-watching the films using the embodied knowledge from site. The analysis Coding allowed us to make the choice of fragments transparent, quantify frequences and locations of practices, household dynamics and the use of appliances, to identify key scenes for further analaysis and create a database that can be resampled. The paper argues that even fictional films are firmly grounded in everyday life and routines and especially fragments that are used to portray ‘normalised’ being at home can be used as an unused source to study everyday life at home, transitions in material culture and the adoption of new technologies. The novelty of the research lies in its’ methodological approach to use film data as a reflective tool to understand energy consumption patterns and help to formulate exciting, relevant research questions for fieldwork. It highlights the importance of arts and humanities research in mediating and humanising often highly technical approach of energy studies.
