Item Compact Fluorescent Lamps and Electricity Consumption Trend in Residential Building in Ilorin, Nigeria(International Journal of Energy Sector Management, 2011-06-21) Sule, B. F.; Ajao, K. R.; Ajimotojan, H. A.; Garba, M. K.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.Item Discharge Generation using Combined Thornthwaite Water Balance and IHACRES Models in Central Nigeria: A Case Study of the Asa River Basin(Annals of the Faculty of Engineering Hunedoara, International Journal of Engineering, 2015) Bilewu, S.
