Illumination of sporting arenas is essentially based on floodlighting. In this thesis the design procedures, calculations and factors for floodlighting were applied to a football field and the best aiming points to achieve the most uniform illumination using Monte Carlo Analysis programmed in MATLAB. A more uniformly illuminated field, would have less glare, but the more uniformly designed illumination was checked whether it would lead to less energy consumption and hence reduction in project cost. The illumination which was simulated by the Pointby- Point equation derived in algebraic form with adjustments for light intensity changes had the result depicted in Isolux contours. The contours showed visually that the Monte Carlo Analysis result was satisfactory and a further visual display of the uniformity gradient showed that the result at the best aiming point had the highest uniformity gradient of 0.027 Lux/m compared to other points that gave 0.021 Lux/m, while the field with random aiming points even gave a negative gradient of -0.001 Lux/m. As a field is a mirror image about its width and lengthwise centres, the result in the quadrant of study was applied to give the final illumination and isolux of the whole field. Further work could extend the study to other types of arenas and compare results with practical measurements using goniometer and photometer.
