Abstract
This study evaluates the pattern of energy usage at
the twenty-eight residences of the University of Johannesburg
during the 2016 academic year. The study investigates the trend
of energy consumption based on total energy usage per residence
in terms of the number of students at each of the residences on a
monthly and daily basis. The data employed in this study were
collected over a period of eleven months which is the overall
effective academic calendar. The results obtained showed a
contrast between the total energy usage per residence and energy
usage per student. Sophia town residence recorded the highest
total annual energy usage of 149286 kWh while Takalani
residence recorded the least which was 97093 kWh of all the
residences considered in this study. However, when energy
consumption was measured as a function of number of students
in each residence, Goudstad residence recorded the highest
monthly energy usage per student (450.69 kWh), followed by
YMCA (389.09 kWh) while the least monthly energy usage of
51.30 kWh was recorded in Maqhawe residence. Similarly,
results obtained from the study on daily energy usage per student
in the last five months of the 2016 academic year showed
Goudstad residence (23.32 kWh) and YMCA (20.34) as the two
residences with the highest daily energy usage per student
respectively. However, the energy usage does not follow a regular
pattern within the period under consideration.
