Globally, energy conservation to reduce the running cost of buildings especially institutional buildings have been a priority. Efforts have been geared towards achieving this through design process. The importance of daylighting in administrative buildings has long been acknowledged as a valuable source of energy savings and visual comfort. In Nigeria, administrative buildings are the top energy consumers. The performance of daylighting in administrative buildings was studied in this research work. In carrying out the study, a major administrative building has been selected for this analysis. Various parameters were generated from existing research work on the indicators and determinants of daylighting performance of an administrative building and a simulation program of the building was carried out to determine the result. With the purpose of analysing the information gathered, a descriptive analysis was used to analyse the performance of daylighting in the building, which was explained further in the methodology. There search offered simulation findings using the software Insight360®to determine the performance of daylighting in percentage at different areas in the building that is expose to direct sun light with the result stating that daylighting decreases slightly towards the middle of the space at an average of 31.7 %. This is due to the extent at which light travels as well as other surfaces that reflect and absorb light, resulting in a reduction in the intensity of the light. Towards the extreme of the space, daylighting diminished to a minimum level of 2.9% due to the light exposure rate and total material absorption. In general, the design of administrative buildings should be such that daylighting performance is optimized from the design stage with the aid of Building Information Model (BIM) software to ensure proper lighting-based illumination.
