A few years ago, a small, hot country like Qatar outbidding rich and developed countries and hosting a mega event like the FIFA World Cup would be a faraway dream. However, in 2022, Qatar showcased the latest smart technologies, including VAR, smart stadiums and a connected football fitted with sensors that collect real-time data such as the ball's location, speed, and direction, to conduct a phenomenal World Cup. This blog mainly discusses the smart cooling system, efficient crowd and stadium management that Qatar used to facilitate the smooth functioning of the FIFA World Cup in one of the world’s hottest climates.

The extreme geography and climate conditions of Qatar were the major challenges the government faced in hosting the World Cup. The average temperature, which often surpasses 40°C (104°F) during the summer, can cause serious health hazards to both athletes and spectators, FIFA demanded the temperature be lowered to  32°C (89.6°F) prioritising the importance of the health and safety of the participants.

Qatar has abundant fossil fuel resources at hand to ensure the smooth functioning of the sports event. However,  the country, aligning with the principles of sustainability and environment-friendly practices, adopted a more sustainable approach to cooling its World Cup stadiums. The fundamental technology used was Mechanical Vapour Compression Refrigeration, which operates using four key components: a Compressor, Condenser, Expansion Valve, and Evaporator. To reduce the Compressor’s energy consumption, as it is the most energy-intensive component, Qatar heavily relied on solar power.

Dr. Saud Ghani, famously known as Dr. Cool, played a pivotal role in developing the cooling system used in the World Cup stadiums. Dr. Ghani’s expertise lies in the field of Automobile Cooling Research, and he devoted his expertise to the challenge of efficiently cooling the entire stadium. His innovative approach scaled up the principles of air conditioning used in cars to develop an effective ambient cooling solution for large stadiums. Dr.Saud referred to the technology as 'Targeted or Spot Cooling'. Targeted or Spot Cooling is a technology that cools the specific areas where people are present. The treated air reaches the venues through the stadium seats specially constructed of perforated material. Smaller air diffusers are placed under each seat to blow cold air at ankle level toward the cheering fans, and football-sized nozzles alongside the field to cool the playing field. The cooling technology in the Qatar World Cup stadiums involves metered air intake, filtration, cooling, and distribution. This system ensures that the stadiums remain at the required temperature and humidity, constructing some of the coolest stadiums in the world.

The knowledge and expertise from this experience can be utilised in future events and projects organised in areas where intense heat is a health hazard. These practices also have virtue because of their sustainability and environmental advantages. The Qatar World Cup not only projected to the world the Arab country's ability to host a world-class sporting event but also underlined its dedication to innovation, sustainability, and the well-being of athletes and fans alike. Qatar has set a new standard for future World Cups and other major events held in challenging climates by smartly utilising cutting-edge cooling technologies and initiating a new era of possibilities in stadium design and engineering.
