Abstract
The study used energy audit to determine where, when, why and how electrical
energy is being used in selected bank buildings in Zaria. The information was
used to identify opportunities to improve efficiency, decrease energy cost and
reduce greenhouse gas emissions that contribute to climate change. The study
employed both primary and secondary sources of data. Questionnaires were the
instruments of the primary data collection while information from
manufacturers’ manuals, catalogues and maintenance records of the banks
constituted the secondary data. The findings indicated that the average electrical
energy consumption and cost for the four (4) bank buildings are 7,412.26
kWh/month and N63,004.14/month before retrofitting. The actual energy
consumed (estimated wattage Rating on nameplate of appliances/equipment)
was also calculated and compared to the consumed energy using One-way
ANOVA. It was concluded that energy usage in the bank buildings involved
much wastage especially in the area of lighting, cooling and plug loads. An
energy efficiency programme which covers lighting, cooling and the plug loads
was recommended.
