Occupant behavior has been widely considered as one of the key influencing factors on building energy consumption. The complexity its formation mechanism and dynamic interaction with buildings have aroused extensive discussion. However, there remains a lack comprehensive systematic review to provide panorama occupant consumption research. This research, therefore, aims (1) explore evolution research; (2) investigate knowledge base domains (3) identify current research gaps propose future directions. Bibliometric approach content analysis were applied 2791 relevant articles published from 2001 2022. It was found that focus evolved simple discussion individual at beginning information-based complex behaviors. A total 45 keywords 10 clusters identified. Eight directions finally recommended based identified researcher gaps, including algorithmic innovation, multi-source heterogeneous data fusion, interdisciplinary, extension standardization behavioral models, diversification types, synergism collective perspective, novel intervention strategies. differs previous ones because it could minimize subjectivity bias compared traditional manual review. results this can potential researchers sufficient in field inspire them directions, which contributes further achieving energy-saving goals perspective occupants' buildings.

Abstract Cities are expected to face daunting challenges due the increasing population in near future, putting immense strain on urban resources and infrastructures. In recent years, numerous studies have been developed investigate different aspects of implementing IoT context smart cities. This has led current body literature become fairly fragmented. Correspondingly, this study adopts a hybrid review technique consisting bibliometric analysis, text-mining content analysis systematically analyse connected IoT-enabled cities (IESCs). As result, 843 publications were selected for detailed examination between 2010 2022. The findings identified four research areas IESCs that received highest attention constituted conceptual structure field. These include (i) data (ii) network communication management technologies, (iii) security privacy management, (iv) collection. Further, knowledge related these was critically analysed. singled out seven major associated with implementation should be addressed by future studies, including energy consumption environmental issues, issues security, interoperability, ethical scalability adaptability as well incorporation systems into development plans Finally, revealed some recommendations those interconnected effective integrations within policies support net-zero futures.
