Kier Group has provided the solar energy system for a new 500-seater 'model' stadium in Qatar powered by sustainable, environmentally friendly technologies in preparation for hosting the 2022 World Cup.

Designed by Arup Associates, the distinctive, zero carbon stadium was a major driver in Qatar’s successful 2022 FIFA World Cup bid and sustainability programme and will be used as a development platform to refine technologies for application across Qatar and potentially across all arid regions.

The stadium has been designed and built as a model to demonstrate how sustainable technologies can be used to prevent temperature and humidity reaching extreme levels within a stadium without expending vast amounts of energy cooling outdoor spaces.

Connected to the structure’s electrical system and national grid, the solar panels located on a sun farm just outside the stadium will operate all year round, continuously exporting electrical energy to the national grid.

During the World Cup, a higher electrical demand will bring electricity back into the facility from the national grid.

The prototype building was designed in just six weeks and built in six months, in time for FIFA delegates to visit the site.

The stadium also uses the sun’s heat, captured by solar thermal collectors, to cool the stadium.

This system works by piping hot water from collecting tubes into a storage tank and then to an absorption chiller that charges the ice store to cool the facility.

The stadium also features a motorised, rotating lightweight roof, designed to shield the stadium from the sun and offer wind protection during matches.

Qatar now plans to build 12 full-size, carbon-neutral stadiums following the success of the test stadium.
