7 out of 8 stadium venues in Qatar are air-conditioned


Seven of the 8 stadium venues in the ongoing World Cup in Qatar are air-conditioned solar energy. According to information from FIFA, the stadium areas are:

  • The Al Bayt stadium was built at a cost of $847 million with a capacity of 68,895
  • The Al Janoub stadium was built at a cost of $656 million with a capacity of 44,325
  • The Ahmad Bin Ali Stadium was built at a cost of $360 million with a capacity of 45,032
  • Al Thumama stadium was built at a cost of $342 million with a capacity of 44,400
  • The Education City stadium was built at a cost of $700 million with a capacity of 44,667
  • The Khalifa International stadium was built at a cost of $374 million with a capacity of 40,000
  • The Lusail stadium was built at a cost of $767 million with a capacity of 80,000
  • Stadium 974 was built at a cost of $717 million with a capacity of 40,000. This stadium is naturally ventilated and does not require air conditioning. According to FIFA, this stadium is designed to be naturally ventilated and does not require air conditioning.

Meet Dr. Cool: Dr. Saud Abdulaziz Abdul Ghani, also known as Dr. Cool, a professor of mechanical engineering at Qatar University. He is the engineer behind the air-conditioned stadium areas used for the 2022 World Cup in Qatar. Dr. Cool has been working on the solar air-conditioning mechanism for 13 years.

Solar for air-conditioning: The air-conditioning system in the stadium areas is powered by the Al-Kharsaah solar farm in Doha. The 800 megawatts (MW) peak solar farm was completed in October 2022 by TotalEnergies, Qatar Energy Renewable Solutions, and Marubeni. The solar farm covers 10 square kilometers (the equivalent of about 1,400 soccer fields). The solar farm project costs $467 million (1.7 billion Qatari Riyals), and consists of about 1.8 million solar panels.

the solar farm incorporating two million high-efficiency bifacial modules mounted on a single-axis tracker. The panels are equipped with photovoltaic cells on the front and back, which allow them to capture the direct rays of the sun on one side, and capture the rays reflected on the ground on the other side – thus optimizing the production of electricity . The key advantage of using bifacial panels is to increase energy production by using the second part of the module

How it works: A The controlled microclimatic bubble covers each spectator (the nozzles are placed under the seats) and covers the field (the air vents are placed around it), at a height of no more than 2 meters at any point inside the enclosure. Pre-cooled air enters through grills built into the stands and large nozzles next to the pitch.

Using the air circulation technique, the cooled air is returned, cooled again, filtered, and pushed outside where it is needed. According to Dr. Ghani, those who work in cooling systems don’t just cool the air, they clean it.

  • “We are clearing the air for the audience. For example, people with allergies have no problems inside our stadiums because we have the cleanest and purest air there is.

Dr. has told FIFA said that hot air is prevented from entering the stadium areas.

  • “The most important thing to cool effectively is that you don’t want the outside air to enter the stadium. That’s why the size and design of the stadium must be studied and changed accordingly so that it can keep the hot air in enter the stadium.”

According to Dr. Ghani, air conditioning accounts for only 20% of the annual electricity consumption in the stadium areas. Therefore, the stadium areas can be used 24 hours a day, seven days a week, all year round.

A people-centered technology: According to Dr. Ghani, the technology is deployed using spot cooling, which means it can only cool the areas where people and players are. He told GOAL.com that he and his team use the best computers and technology to provide the highest temperature so that World Cup fans from all over the world feel comfortable during the games.

Dr. pointed out. Ghani is the fact that the cooling technology will keep the temperatures inside all areas of the stadium regulated at a comfortable 23-25 ​​degrees Celsius, regardless of the mercury readings outside. Also, the cooling technology has a filter for dust and odor, and since the air is recycled, it ensures that the air is purified to perfection. Also, the cooling technology helps the athletes to perform at the highest level, unlike traditional stadium areas where water splashes are the main thing.

For the record: According to FIFA, the Lusail Stadium received a 5-star rating from the Global Sustainability Assessment System. Recycled water is used to irrigate plants around the stadium and water-efficient fixtures as well as leak detection systems operate in the stadium.
