“…CFD studies validated with wind tunnel experiments have shown that the roof configuration and the porosity of the stadium envelop have great impact on the wind distribution at both pitch level and spectator terraces and consequently on the induced wind comfort conditions [4][5][6][7]. Additional studies revealed the importance of providing ventilation openings to promote natural airflow and ventilation at the occupied areas of the stadium bowl [6,8,9].…”

Abstract. The complexity of the built environment requires the adoption of coupled techniques to predict the flow phenomena and provide optimum design solutions. In this study, coupled computational fluid dynamics (CFD) and response surface methodology (RSM) optimisation tools are employed to investigate the parameters that determine the wind comfort in a two-dimensional stadium model, by optimising the roof geometry. The roof height, width and length are evaluated against the flow homogeneity at the spectator terraces and the playing field area, the roof flow rate and the average interior pressure. Based on non-parametric regression analysis, both symmetric and asymmetric configurations are considered for optimisation. The optimum design solutions revealed that it is achievable to provide an improved wind environment in both playing field area and spectator terraces, giving a further insight on the interrelations of the parameters involved. Considering the limitations of conducting a twodimensional study, the obtained results may beneficially be used as a basis for the optimisation of a complex threedimensional stadium structure and thus become an important design guide for stadium structures.

“…Fiala et al (1999) simulated Australia's main Olympic Stadium and revealed that lack of air circulation and ventilation in shaded seating areas can cause higher thermal discomfort than well-ventilated unshaded seating areas. Bouyer et al (2007) underlines the segregation of the convective heat transfer between standing and seating positions when simulating stadia, because of the contact of the plastic chair with the body that can be considered as an extra clothing insulation factor. The authors visualized through virtual reality platform "EVE" two stadia, Stade de France in France and the Atatürk Olympic stadium in Turkey.…”

Thermal comfort in hot and arid outdoor environments is an industrial challenging field. An outdoor air-conditioned area was designed and built to host sport and social events during summers 2014 and 2015 in Qatar. This article presents a thermal comfort analysis of the outdoor air-conditioned area using computational fluid dynamics, on-site spectators surveys, and on-spot climatic measurements. The study utilized computational fluid dynamics to develop a thermal comfort model of the outdoor air-conditioned area to predict the thermal comfort of the occupants. Five different thermal comfort indices; mean comfort vote, cooling power index, wet-bulb globe temperature index, Humidex, discomfort index, were utilized to assess the thermal comfort of spectators within the conditioned space. The indices utilized different on site measurements of meteorological data and on-site interviews. In comparison to the mean comfort vote of the sampled survey, all thermal comfort indices underestimated the actual thermal comfort percentage except the wet-bulb globe temperature index that overestimated the comfort percentage. The computational fluid dynamics results reasonably predicted most of the thermal comfort indices values. The computational fluid dynamics results overestimated the comfort percentage of mean comfort vote, wet-bulb globe temperature index, and discomfort index, while the thermal comfort percentage was underestimated as indicated by the cooling power index, and Humidex.

The 2022 World Cup creates great opportunities for the country of Qatar, but also poses significant challenges. In this study the main challenge of maintaining thermal comfort conditions within the football arenas is presented, with respect to the heat stress index (HSI) and the aero-thermal comfort thresholds established for opened stadiums. Potential cooling strategies for delivering tolerant comfort levels are introduced, followed by their functional strengths and limitations for the hot-humid climate of Qatar. An estimation of the cooling load for semi-outdoor stadiums in Qatar is also presented. The results, produced by dynamic thermal modelling, indicated that a load of 115 MW h per game should be at least consumed in order to provide both indoor and outdoor thermal comfort conditions. Finally, the use of solar energy technologies for the generation of electricity and cooling are evaluated, based on their viability beyond the 2022 World Cup event, towards the nation's targets for sustainability and lasting legacy. Highlights:• Provision of aero-thermal comfort conditions within the sport facilities.• Higher efficiency of solar sorption systems in hot-humid climates.• An estimated cooling load of about 115 MW h per game is required.• Balancing techniques to meet carbon neutrality commitment.• Forthcoming local and national community benefits.
