Electrical Energy Usage Analysis for all Residences of a South African Academic Institution

摘要

This study presents an analysis of the energy usage of the twenty-eight residences at the University of Johannesburg during the 2017 calendar year. The paper presents the energy consumption if the residences based on the total energy usage per residence as well as in terms of the number of students at each of the residences for the different seasons of the year. The results of this study show a strong correlation between energy usage and factors such as temperature, time of day and building occupancy. Furthermore, an analysis of the load factors and power factors for each of these residences during different months of the 2017 calendar year revealed possible opportunities for energy saving interventions.
