1.0 INTRODUCTION 1.1 Background of the Study
For many years now, Nigeria has been facing an extreme electricity shortage. This deficiency is multi-faceted, with causes that are financial, structural, and socio-political, none of which are mutually exclusive. There is insufficient cash generation because of these inefficiencies and the power sector is consequently reliant on fuel subsidies and funding of capital projects by the government. With over 150 million people, according to the Nigerian Energy Policy report from 2003, it is estimated that the population connected to the grid system is short of power supply, over 60% of the time and at present only 10 % of rural households and 40% of the country’s total population have access to electricity (Obadote, 2009).
Green building Technology (2007) opines that daylighting provides the opportunity for both energy savings and improved visual comfort. The science of daylighting design is not just how to provide enough daylight to an occupied space, but how to do so without any undesirable side effects. Beyond adding windows or skylights to a space, it involves carefully balancing heat gain and loss, glare control, and variations in daylight availability. For example, successful daylighting designs will carefully consider the use of shading devices to reduce glare and excess contrast in the workspace. Additionally, window size and spacing, glass selection, the reflectance of interior finishes, and the location of any interior partitions must all be evaluated (Ander, 2014).
