A household’s energy behaviour consists of several processes and interactions and involves the decisions and functions of several entities. The topic of this study is to reconstruct, through narrations, the process of designing and implementing the new student dorms at Linköping University through the lens of household energy behaviour. In particular, we aim to investigate how the interactions between entities such as the builders, landlords, users, ventilators, heaters, climate and so forth co-perform energy behaviour in the setting of residential student buildings. Inspired by the actor-network theory, the study treats energy behaviour as a hybrid collectif. It is the relations and their heterogeneity that are important in this approach. The project studies how heterogeneous relations among everyday practices, human experiences and interactions with nonhumans enact energy use patterns.
