Abstract: In this paper, an electric energy reduction model for campus using the method of controlling energy consumptions is proposed. The study used the building of Engineering Faculty of Universitas Andalas, Indonesia, as the object of research. In these models, the amount of electric energy consumption for a month is estimated as needed. Estimation of electric energy requirement is mapped from faculty activities, activities schedule, standards for power quality, standard lighting, room temperature standards, load technology and human behavior in the building. The parameters used in the calculation are obtained from direct observation in the field. Furthermore, the real-time monitoring of electrical energy system is designed with the installation of power logic on the substation faculty buildings and transmitted energy data through the campus web. The measurements of power and electrical energy consumption for one week using Fluke Power Analyzer 435 series II is needed for the design base of energy monitoring system. In this study, the difference between the results of real-time monitoring and the estimation of energy consumption in the object of study during October 2018 was 9,151,664 kWh (21.86%). This is a form of waste of electrical energy because of the use of electric energy in the room and time that is not appropriate. The initial solution to the waste indicated above is the management approach. However, this designed model is able to integrate all possible paths to reduce electric energy consumption, such as: improving power quality, increasing efficient technology in the load, and reduction of energy waste.
