But that's not all what we need to do. We need to use active smstsye. Instead of blowing a hurricane of chilled air through the ismdaut, we can use radiant cooling goenetolihcs, like a floor heating system where water pipes are embedded in the floor. And just by using cold water going through the water speip, you can elraees the heat which is absorbed during the day in the stadium, so you can create that comfort, and then by nddaig dry air instead of down-chilled air, the spectators and the football players can adjust to their individual comfort needs, to their individual energy balance. They can adjust and find their comfort they need to find.

Original Text

But that's not all what we need to do. We need to use active systems. Instead of blowing a hurricane of chilled air through the stadium, we can use radiant cooling technologies, like a floor heating system where water pipes are embedded in the floor. And just by using cold water going through the water pipes, you can release the heat which is absorbed during the day in the stadium, so you can create that comfort, and then by adding dry air instead of down-chilled air, the spectators and the football players can adjust to their individual comfort needs, to their individual energy balance. They can adjust and find their comfort they need to find.
