Air conditioning, glass windows: $1.3bn World Cup venue has quirks ahead of France-Spain semifinal

France and Spain will meet in a blockbuster World Cup semifinal on Tuesday at AT&T Stadium in Dallas, Texas. The $1.3 billion venue, home of the NFL's Dallas Cowboys, has been temporarily renamed Dallas Stadium for the tournament under FIFA branding rules.

While the stadium is one of the most impressive in the United States, it has drawn attention for two unusual features that could influence the game: its powerful air conditioning system and massive glass windows at both end zones.

Air conditioning blamed for 'surprise' goal

During England's group-stage win over Croatia at the same venue, commentator Jim Proudfoot suggested that the air conditioning may have affected the flight of the ball on Croatia's opening goal. England goalkeeper Jordan Pickford got a hand to Martin Baturina's long-range strike but could not keep it out, and Proudfoot speculated that cool air from the AC system could have caused extra movement, similar to altitude effects.

• England beat Croatia 4-2 in their opening match at AT&T Stadium.
• Croatia's first goal by Martin Baturina was a long-range shot that beat Jordan Pickford.
• Commentator Jim Proudfoot suggested air conditioning may have added movement to the ball.
• FIFA covered the stadium's huge glass windows at both ends to comply with branding rules.
• The glass windows are a signature feature of the Cowboys' home field, allowing outside views.

What's next

With a place in the World Cup final at stake, both France and Spain will be wary of any environmental factors that could decide a tight contest. The stadium's air conditioning and covered glass windows add an extra layer of unpredictability to what promises to be a thrilling semifinal.
