Keywords: Smart Buildings, Internet Technology, Civil Engineering, Energy Efficiency, Sustainability Introduction Civil engineering and construction sectors are undergoing a transformative shift, propelled by the rapid integration of Internet Technologies, notably the Internet of Things (IoT) (Miorandi, D., Sicari, S., De Pellegrini, F., & Chlamtac, I., 2012). Among the prominent outcomes of this technological revolution is the emergence of "smart buildings". These structures incorporate IoT technology to maximize energy efficiency, sustainability, and user experience, symbolizing a new era of innovative architecture (Shah, S. F. A., Iqbal, M., Aziz, Z., Rana, T. A., Khalid, A., Cheah, Y.-N., & Arif, M., 2022). Global urbanization trends and the concurrent increase in energy consumption necessitate sustainable solutions to minimize the environmental impact of expanding cities (Arkar, H., Sui-Reng, L., Theingi, A., & Amiya, B., 2023). With growing calls for energy-efficient and sustainable infrastructures, smart buildings have become critical in addressing the myriad challenges of urban environments (Hashem, I. A. T., Chang, V., Anuar, N. B., Adewole, K., Yaqoob, I., Gani, A., ... & Chiroma, H, 2016). This comprehensive review paper explores the intersection of civil engineering and IoT within the context of smart buildings, highlighting the imperative need for energy efficiency in modern infrastructural development. Further, the adoption and application of emerging technologies such as artificial intelligence, machine learning, and big data analytics underscore the potential for the evolution and innovation in the construction industry, shaping the future trajectory of infrastructure development (Theingi, A., Sui- Reng, L., Arkar, H., & Amiya, B., 2023). A "smart building" is a structure that leverages advanced Internet Technologies, particularly IoT devices, to monitor, control, and optimize various building systems, encompassing automation, security, and energy management (O’Donovan, P., Leahy, K., Bruton, K. & O'Sullivan, D. T. J., 2015). This optimization is facilitated
