Abstract
Purpose – The purpose of this study is to examine the electricity consumption trend in residential
buildings using incandescent lamps and retrofitting with compact fluorescent lamps (CFLs).
Design/methodology/approach – Questionnaires were administered to capture the necessary data
from three randomly selected residential estates in Ilorin, Nigeria. In total, 8,840 sampled incandescent
lamps were retrofitted with CFLs. The electric energy in kilowatt hour (kWh) consumed prior to
replacement for three months was compared with kWh consumption after retrofitting and analyzed
employing t-tests.
Findings – The three-month average electricity consumption of ten households for the University of
Ilorin GRA quarters and Lower Niger River Basin staff quarters pre- and post-installation were 20,259
and 13,010 kWh, and 46,891 and 29,588 kWh, respectively. Results show that there were significant
differences between the observed and tabulated values for the pre- and post-installation of CFLs,
respectively, at 5 per cent confidence level. About 40 per cent reduction in electricity consumption was
achieved through deployment of CFLs in the residential households.
Originality/value – This paper demonstrates how retrofitting of incandescent lamps with CFLs can
bring about possible reduction in electricity consumption in residential households in Nigeria.
