ABSTRACT
Widespread demand for sporting activities in the night has led to the integration of
lighting design in the development of sporting arenas due mainly to lower
temperatures at night, increase in demand for sporting facilities and leisure
considerations. 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.
