The Supreme Committee for Delivery & Legacy (SC) is developing a "lessons-learned" document and workshop addressing all elements that resulted in the successful delivery of a cooled open-air Fan Zone in Qatar. This exercise will cover design, construction, procurement, finance and legal areas and will later be used to brief and train the SC's technical teams in addition to personnel from other departments.

Tamim El Abed, the SC's lead engineer for the Brazil 2014 Fan Zone said: "After hosting a successful fan zone, I think it's clear that we have entered delivery mode. I believe this project will help extract the element of fantasy often linked to the idea of cooling football stadiums."

El Abed added that delivering a cooled fan zone for 1,500 people on a daily basis was the result of "straight forward engineering." The SC technical team will apply lessons learned during the testing phase of the cooling technology and adapt them across different structures.

The SC is now also evaluating the possible uses of the Fan Zone structure and ways to continue testing the cooling technology in different weather conditions and ultimately, reinventing it for continued productive use.

The open-air Fan Zone was used by the SC to test the prototype cooling technology that will be utilised at the 2022 FIFA World Cup Qatar™. The results from the tests were very positive, with temperatures on average 12 degrees Celsius lower inside the venue.

The technological achievement utilised four cooling columns, located at strategic points within the venue, which delivered cooled air into the Fan Zone.

The flexible cooling system then responded to different climatic conditions, using a range of delivery methods, such as dedicated ventilation units to funnel sufficient cooled air; high level jet nozzles to restrict prevailing winds; and low level diffusers to provide comfort for the spectators.

Other methods included using mechanically adjustable dampers to regulate air – with an external weather station providing real time data and injecting cooled mist into the venue to enhance the evaporative cooling effect.

The application of these technologies helped SC engineers develop an understanding of how to create the perfect energy efficient system ahead of the 2022 FIFA World Cup Qatar™.

This system will be further enhanced and refined as other technologies are developed, with SC engineers investigating the feasibility of utilising cooling capabilities for a variety of environmentally beneficial purposes.

The data collected during this testing phase will help ensure that efficient cooling technology is in place during the 2022 FIFA World Cup Qatar™, and that the technology developed will leave a lasting legacy for the country and others with similar climatic conditions.
