International. More than 5 years before the START of the FIFA World Cup, host country Qatar has completed the installation of its cooling technology at the Khalifa International Stadium, built in 1976 in Doha. The stadium has undergone an estimated $90 million renovation.
The World Cup in Qatar represented a great challenge for the competition, due to the extremely high temperatures in summer. That's why a FIFA task force decided that the tournament would take place between November and December when temperatures can reach 30°C.
HVAC technology is based on the cooling district: the nozzles bring ice water from an energy center located one kilometer from the stadium. Tested during the Emir Cup final on May 19, 2017, temperatures reached 20°C on the pitch, and 23°C in the spectator stands.
"The cooling district means that the cooling technology is 40 percent more sustainable than conventional techniques. We have an energy center located one kilometer from the stadium, from where the ice water in a pipe is brought to the place. Once it gets here we are pushing the cold air over the playing field and spectator seating areas," said Saud Ghani, professor at the College of Engineering at Qatar University, and project leader.
"The cooling nozzles were specially designed in Qatar, with plastic moving parts that are more durable and allow air to be pushed into the area we want it to reach," the professor added.
