Application of the Internet of Things (IoT) for Energy Efficiency in Buildings: A Bibliometric Review.

Abstract

Buildings are experiencing tremendous transformation, where Internet of things (IoT) is been used to transform traditional buildings into smart structures. While there are viable IoT techniques, developing IoT applications and operations to fully realise the technology's promise is needed. This may be done successfully by bridging the gaps in the present research to establish a foundation for future investigations. This study analysed extant literature in IoT (between 2008 and 2022) through a bibliometric review to tease out critical measures for their integration and transformation. The study adopted a science mapping quantitative literature review approach and employed bibliometric and visualisation techniques to systematically investigate data. The Scopus database was used to collect data and VOSviewer software to analyse the data collected to determine the strengths, weights, clusters, research trends in IoT. Important findings emerging from the study include recent literature by various researchers on IoT applications in buildings. The shift in recent patterns of research from developed to developing countries. Eighty-nine (89) keywords were analysed and divided into six clusters. Each cluster is discussed to present its research area and associated future studies in relation to Smart buildings. This paper uses bibliometric analysis to unpick recent trends in IoT and its relevant application to buildings. The paper provides a blueprint for future IoT research and practice, needed awareness and future strategy directions for IoT applications in construction. This creates opportunities to transition to more sustainable construction sector
