Abstract: Day lighting has often been recognized as a useful source of energy savings and visual comforts in educational spaces. Occupant in building need a very good lighting in their work environment. Natural lighting helps students and other workers to be more comfortable and productive. Effective use of natural Day lighting in library buildings has the potential to maximize the benefits of visual comfort, reduce energy usage, and achieve a qualitative building environment in terms of thermal comfort for the building users. Even though the number of possible alternatives that can be generated for integrating day lighting in buildings architecturally is challenging.
Allowing direct day light into building space will also affect the thermal comfort of the space. Buildings with big window opening of glazed surfaces also affect the thermal and visual discomfort, because of the large income of solar radiation into the building.
This paper study the use of day lighting design to improve visual comfort, energy efficiency and thermal comfort of Library located at Ahmadu Bello University, Zaria Nigeria. The natural day lighting performance of this base case study was evaluated in terms of daylight factor, luminance, room depth and glare index. It has been found that the day lighting performance for library buildings is quite effective in order to achieve a qualitative and comfortable building. In order to gain more ideas about this study, data analysis and computer simulation are taken into consideration in order to make the comparative result of the study. The use of computer package simulation namely RELUX was used for the study.
Keywords: Day lighting, Artificial Lighting, Energy Saving, Visual comfort, Thermal comfort.
