Energy Management Based on Internet of Things Maryam Alsaeedi 1,2 , Basel Ali 1(B ) , and Thomas Mazzuchi 1 1 The George Washington University, Washington, D.C., USA allamh3@hotmail.com 2 College of Business and Finance, Ahlia University, Manama, Bahrain Abstract. The Internet of Things (IoT) is a fast-growing reality with tremendous physical entities connected to the internet. Energy management through IoT is one of the recent efficient applications of it. This research analyses the energy management based on IoT technology for AC control for a residential unit. It shows the management capabilities of a smart home AC system as well as an estimation of the savings in terms of power consumed and cost. It is found that there is a 29% decrease in energy consumption when the smart AC system acts to manage the power consumption of the units in the home. As a result, significant financial benefit is achieved. 1 Introduction Energy conservation is becoming more and more trending as the need for sustainability increases. The use of Internet of Things (IoT) helps in achieving this need and makes it a reality. The Internet of Things (IoT) is considered as one of the recent innovative milestones in which the interconnection between objects regulated by specific protocols resulted in an intelligent promising data generators for creating value and enhancing the quality of life [1–5]. This research studied the effect of integrating IoT based systems in Bahraini residential units to manage energy utilization. The hypothesis tested was: H1: IoT based energy management will achieve energy conservation. The building under study was a residential household for a family of five members. It was a three-story house built on a land plot size of 301.5 m 2 . This study covered the air conditioning systems only since 49% of the total energy consumption in a typical Bahraini house is due to air conditioners [3]. Electricity consumption data of the house was extracted from the historical energy consumption readings available from the Elec- tricity and Water Authority (EWA). Tariff rates details were also collected from EWA website. Information about the AC units, house floors diagrams as well as the distribution of appliances were also considered. Moreover, temperature and humidity data has been collected from the Meteorological Directorate to better support the study. Also, pricing for the IoT based devices were collected from the supplier. 2 Smart AC System Two modules were used in this study to convert the current AC systems into smart sys- tems: The “CoolPlug” and “CoolLinkHub”.
