Evaluation of Building Energy Use in South Western Nigeria

The study investigated the energy needs of buildings in South Western Nigeria; examined factors influencing energy loss in buildings and examined the factors influencing implementation of energy saving opportunities in South Western Nigeria with a view to providing information that will enhance economic (cost) and environmental sustainability. The study made use of primary data collected by carrying out building energy audits on 40 buildings that utilize the heating, ventilation and air conditioning (HVAC) system in the study area selected through a purposive sampling technique and administration of questionnaires to the building users. Data collected included energy needs in buildings, building user’s needs for thermal comfort, air leaks in building envelopes and the envelope characteristics, and user's agreement on energy saving measures. The data were analyzed using frequency, percentage, mode, mean score and heat transmission formular. The results on energy needs revealed that space cooling accounts for the highest (100%) energy need than space heating (10%) in South Western Nigeria. Results on energy loss revealed that inadequate envelope from air leaks with external windows having the highest percent (72.5%) of air leaks, and (67.5%) unawareness of building users are factors influencing energy loss in buildings. The results on energy saving opportunities revealed that efficient building insulation is a vital measure (MS= 3.8) to save energy in buildings in South Western Nigeria and it is influenced by financial capability of building users (MS= 3.7). The study concluded that efficient building insulation is a vital measure to enhance energy savings in buildings and it is greatly influenced by the financial capability of the building users.
