Cooling Qatar’s World Cup Stadium.

The canopy roof, the first of its kind in the world, moves to provide  shade within the .

A lot of the criticism surrounding Qatar’s bid for the 2022 World Cup surrounded the heat, given that most of the games will be played during the country’s hottest months of the year.

The fact that Qatar planned to air condition its stadiums has also been subject to some scepticism, but as engineering giant Arup reveals, it is possible to keep football stadiums both cool and sustainable even in the country’s hottest months.

The model stadium was built to prove that Qatar could deal with its hot and humid climate.
Arup designed a 500-seat, carbon-zero model stadium as a development platform to refine sustainable technologies for application across Qatar and potentially across all arid regions. The stadium was designed to demonstrate to FIFA that the harsh climate over the summer months is no longer a barrier to hosting global events.
The showcase is based on three key aspects: an exciting architecture and structure which develops traditional passive design ideas to a new energy-saving and comfortable architecture; photovoltaics that convert the energy of the sun into electricity and capturing and converting the sun’s heat into for summertime air conditioning using under-seat supply.
The canopy roof, the first of its kind in the world, moves to provide  shade within the  and insulates against the hot sun in summer.
In addition to protection from sun-light, the canopy can be positioned to protect from wind during match times and let spectators and players take advantage of natural ventilation. In hot conditions, the canopy can be closed in the run-up to an event to allow  to work at maximum efficiency, using  from the sun to cool down the volume ready for match time in the summer evenings, when it can be opened.
Meanwhile, the venues’ solar panels will operate year-round, continuously exporting electrical energy to the grid. On a match day, the higher electrical demand will bring electricity back into the facility from the grid.
This electricity, together with generators using biofuels, provide robust and reliable power for both technical and general power, so the events are assured power during the World Cup. The amount of electricity generated in this way from the sun exceeds the amount of electricity imported for events over the year, making the facility zero carbon for electricity.
