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.
Door enkel koud water door de buizen te laten stromen, kun je de warmte die overdag in het stadium is geabsorbeerd, afvoeren zodat je dat comfort kan creëren, en door droge lucht toe te voegen in plaats van gekoelde lucht, kunnen de toeschouwers en de spelers zich aanpassen aan hun individuele comfortbehoeften, hun individuele energiebalans.
