Investigation of Electrical Energy Use Efficiency of Students’ Hostel in Gidan-Kwano Campus of Federal university of Technology Minna

Abstract

This paper presents the result of an electrical energy audit conducted at the students’ hostels of the Federal University of Technology Minna, Niger State, Nigeria. The aim was to ascertain the electrical energy consumption pattern, calculate the amount of electrical energy consumed, spot areas of waste and find measures to curb such waste. A walk-through audit and investigation through questionnaire and oral interviews was used to gather required data. SPSS and Microsoft Excel software packages were used to analyze the data. Electric cooking element ranked top in energy consuming loads, followed by lighting and fan loads. This was due to the use of unregulated hot plates and poor user habits in the hostels. Electricity bill was estimated based on the connected load. Possible energy saving options were highlighted, resulting in a 38% savings on electricity bill.
