Assessment of visual comfort of spectators in stadia

Résumé

Stadia are prestigious buildings, sculptures of urban structure and venues of different competitions, concerts, religious events, visited by large number of people. Spectators, following day-time events in situ or on the TV expect an evenly illuminated pitch, free of sharp contrasts. The contrast is due to the shadow from the roof and bowl: the shape of the shadow depends on the morphology of the stadium, on the material of the roof, on the time and geographical location. Self intended transparent or translucent roofs partly eliminate the problem, however besides of visual conditions other aspects should not be forgotten: in summer the exposure of spectators to solar radiation may result in serious thermal discomfort. A set of numerical simulation has been carried out with different morphological variations, for different orientations and latitudes in order to determine the seasonal number of hours when the visual requirements are met. A method has been developed to determine the size and shape of the necessary transparent part of the roof of a given morphology, for any orientation, latitude and schedule of event. The results facilitate the consideration of the visual conditions in the early stage of the design.
