Recent Advances in Internet of Things (IoT) Infrastructures for Building Energy Systems: A Review

Abstract

This paper summarises a literature review on the applications of Internet of Things (IoT) with the aim of enhancing building energy use and reducing greenhouse gas emissions (GHGs). A detailed assessment of contemporary practical reviews and works was conducted to understand how different IoT systems and technologies are being developed to increase energy efficiencies in both residential and commercial buildings. Most of the reviewed works were invariably related to the dilemma of efficient heating systems in buildings. Several features of the central components of IoT, namely, the hardware and software needed for building controls, are analysed. Common design factors across the many IoT systems comprise the selection of sensors and actuators and their powering techniques, control strategies for collecting information and activating appliances, monitoring of actual data to forecast prospect energy consumption and communication methods amongst IoT components. Some building energy applications using IoT are provided. It was found that each application presented has the potential for significant energy reduction and user comfort improvement. This is confirmed in two case studies summarised, which report the energy savings resulting from implementing IoT systems. Results revealed that a few elements are user-specific then need all be considered in the decision processes. Last, based on the studies reviewed, a few aspects of prospective research were recommended.

Offline Scaling of IoT Devices in IOTA Blockchain

“…Since their inception, IoT devices have not received the timely upgrade when it comes to the evolution of hardware and software stack [ 15 , 16 ]. Even the communication protocols that came into existence in the late 1980s were ported to cater to the needs of the IoT devices much later; a similar pattern can be observed on other technical innovations as well [ 17 ]. The ignorance ( , accessed on 21 December 2021) even continues on the upgrade and security cycles [ 18 ] where the lack of timely upgrades and a proactive approach towards security has exposed the IoT ecosystem to various types of attacks.…”

AI-big data analytics for building automation and management systems: a survey, actual challenges and future perspectives

“…Thus, BAMSs learn from experiences and historical data for automatically adjusting the indoor conditions (Yaïci et al. 2021 ).…”

Design and fabrication of an IoT-based smart electrical meter for residential energy management

“…Real-time monitoring helps households reduce more energy consumption than monitoring through monthly electricity bills [9], [10]. There have been a great number of studies on electrical energy meters using IoT [11]. The statistics of the different technological and functional aspects found in the literature review are illustrated in Table 1.…”
