“…Png et al [ 23 ] have taken an orthogonal approach to powering sensors by dramatically reducing power requirements for building IoT systems. They investigated an application in which several sensors for analysing air quality can be combined within a single Arduino component for control and data processing.…”

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.

“…The advent of advanced electric hardware systems (such as power circuits) and internet-enabled sensors/devices provides a unique opportunity for implementing IoT in every web-equipped commercial building. For example, Ruano et al [39] and Png et al [40] proposed IoT platforms for intelligent HVAC control in commercial buildings. Ronen and Shamir [50] revealed how IoT provides smart lighting systems by modifying color and intensity of the lights of each room in a commercial building.…”

“…Figure 4 displays the iSEA data ontology and demonstrates the statics and dynamics data. While several programming languages could be utilized for data processing and analysis, we propose XML or Python for iSEA since they have widely been used for faster and more accurate data analysis in IoT approaches and web environments [40,49,151].…”

“…Recently, the Internet of Things (IoT) as a prominent technology is transferring conventional building energy management systems (BEMS) into smart, scalable, efficient, secure, flexible, and real-time systems for easier and greater energy-savings in both residential [28][29][30][31][32] and commercial buildings [33][34][35][36][37][38]. In particular, IoT-based approaches more accurately estimate thermal and scheduling models to minimize energy used by HVAC systems [39][40][41][42][43][44]; these systems currently consume about 50% of building energy consumption in developed countries [45][46][47].…”

iSEA: IoT-based smartphone energy assistant for prompting energy-aware behaviors in commercial buildings

Providing personalized energy-use information to individual occupants enables the adoption of energy-aware behaviors in commercial buildings. However, the implementation of individualized feedback still remains challenging due to the difficulties in collecting personalized data, tracking personal behaviors, and delivering personalized tailored information to individual occupants.Nowadays, the Internet of Things (IoT) technologies are used in a variety of applications including real-time monitoring, control, and decision-making due to the flexibility of these technologies for fusing different data streams. In this paper, we propose a novel IoT-based smartphone energy assistant (iSEA) framework which prompts energy-aware behaviors in commercial buildings.iSEA tracks individual occupants through tracking their smartphones, uses a deep learning approach to identify their energy usage, and delivers personalized tailored feedback to impact their usage. iSEA particularly uses an energy-use efficiency index (EEI) to understand behaviors and categorize them into efficient and inefficient behaviors. The iSEA architecture includes four layers: physical, cloud, service, and communication. The results of implementing iSEA in a commercial building with ten occupants over a twelve-week duration demonstrate the validity of this approach in enhancing individualized energy-use behaviors. An average of 34% energy savings was measured by tracking occupants' EEI by the end of the experimental period. In addition, the results demonstrate that commercial building occupants often ignore controlling over lighting systems at their departure events that leads to wasting energy during non-working hours. By utilizing the existing IoT devices in commercial buildings, iSEA significantly contributes to support research efforts into sensing and enhancing energy-aware behaviors at minimal costs.

“…The number of buildings has grown dramatically in recent decades, thus increasing the demand for air conditioning; this reality makes engineers and architects focus on the energy and operational optimization of the designs and installations of the thermal machines in charge of maintaining thermal comfort conditions within buildings (Png et al, 2019). The energy consumption of air conditioning systems in buildings represents 40 to 60% of the total energy consumption of non-industrial type buildings in tropical countries (Venkateswara and Datta, 2020); (Liu et al, 2020).…”

The aim of this paper is to present a general bibliographic review about recent scientific papers focused on the design and operation of air conditioning systems in green and smart buildings.The suggested review is developed using tools offered by the Scopus academic research directory, with a defined search criteria. Furthermore, the VOSviewer science bibliometric analysis software has been used. This paper has several reviews of cooling and heating systems existing or under development available for residential buildings (green and smart buildings) and some initiatives and research projects from recent years. The present paper is an academic research guide for engineers, architects, and students interested in designing, constructing and efficiently managing the cooling processes of green and smart buildings. Economic powers characterized by large megacities of countries such as the United States of America, China, Italy, Malaysia, Germany and Australia; Nowadays, increasing energy efficiency and decreasing carbon footprint of current and future buildings, both green and smart is considered more important. The most frequent fields of research in scientific contributions related to the cooling of green buildings are: sustainable development, energy efficiency and the construction industry; while in smart buildings they are: energy efficiency, smart grids, energy management.
