Abstract During and after the COVID-19 pandemic, significant changes occurred in lifestyles of residents worldwide. This study aims to develop an activity-based urban energy modelling framework to capture the impact of changes in urban residents’ activity time and location choices on cross-sectoral urban energy demand. The framework employs a utility-based model to characterise the spatiotemporal patterns of urban population activity choices and derives the temporal and spatial variations in energy demand. The model was validated using data from the Guangzhou Resident Lifestyle Survey (GRLS). In addition, this study examines a typical local neighbourhood as a case study, calculating changes in building energy demand resulting from the promotion of home-based, hybrid, and multi-locational working arrangements through scenario settings. Research findings indicate that flexible working arrangements shift daytime energy demand on workdays from office buildings to residential buildings, with this shift also influenced by external climatic factors such as temperature and weather conditions. This study provides a novel activity-based perspective for urban energy management, enabling scholars to gain insights into energy demand trends arising from emerging changes in residents’ activity patterns in fast-growing cities. These insights will assist urban policymakers in formulating cross-sectoral energy strategies and planning measures to enhance community and urban energy resilience.
